]]>We want to give some tips on how to think about choosing the best nozzle for the job.
In the video, you see a comparison with a "normal" sewer nozzle with many water jets, compared to our BL Swiper® with few water jets.
The number of water jets
What are the advantages and disadvantages of many outgoing water jets compared to fewer jets in a nozzle?
The number of times we divide the water flow rate available, the thinner each water jet will be.
A good rule of thumb is to choose a nozzle with fewer water jets to make them as thick and powerful as possible. The disadvantage of fewer jets is that they can create "strips" in the pipe. This usually happens when the material in the pipe is on the sides and is hard packed. If there is any drainage material in pipe, such as loose sand or gravel, these types of nozzles may also create a "strip effect".
Conclusion:
• Fewer jets are always more effective when moving material in pipe, compared to many smaller water jets.
• If pipe needs to be cleaned all around (360˚), more water jets are preferred.
• To be able to adapt to every project, you should always have both options of nozzles available on the jetting truck.
Angles of the water jets
How should one think about the angles of the water jets coming out of the nozzle?
To simplify, we divide the angles of the water jets into three different categories.
Cleaning nozzles with 0–12-degree rear thrusting jets are designed to move material in the pipe. The lower the angle, the more efficiently the material will be transported in the pipe.
At a lower angle, the distance from when the water leaves the nozzle until it reaches the pipe is longer. This is where the inner design of the cleaning nozzle comes in. An optimal water-conducting design keeps the jets together significantly longer behind the nozzle and therefore gives the opportunity to work at lower jet angles and still clean all the way out to the pipe wall. Nozzles with poor internal design will not do the job in larger pipes.
Cleaning nozzles with thrusting rear jets in an angle between13-30 degrees are normally call universal cleaning nozzles. Nozzles in this category often have more rear thrusting jets in different angles. They normally can move material in pipe if there is not too much and are quite efficient. They are also able to clean the inner pipe wall effectively if it is not too hard or greasy material.
Nozzles with thrusting rear jets in an angle between 31-90 degrees is for pure pipe wall washing or descaling. Rotary nozzles are widely used in this nozzle category, but there are also Bomb or Grenade type of nozzles where 50 % of the water jets have an angle of up to 45 degrees and the jet inserts are of the type of fan jets intended for pipe wall cleaning or descaling. These types of nozzles are not designed to move large amounts of material in pipe. If the pipe contains a large amount of material, start by cleaning out the material with a more efficient 0–12-degree cleaning nozzle. After the cleaning is done, run with the 31-90 degree “pipe wall washing nozzle”.
Take care of your water pressure and your wallet
For the nozzle to work effectively, it is important to choose a nozzle that has as little internal turbulence as possible. Turbulence inside a cleaning nozzle creates pressure losses. This means losses of energy, energy for which you paid dearly (diesel/water). The turbulence also produces jets of water with significantly less power. Turbulent water also results in a shorter length of the water jets, which makes the nozzle work inefficiently.
The less turbulence the internal design of the nozzle creates, the more efficient a nozzle is. Then you do not have to throttle up the jetting unit as hard and thus reduce wear and tear on the pump, driveline, and clutches, while saving a lot of diesel, water, and money. This is a No Brainer.
]]>The function of an ejector is based on using an assisting medium at a high speed that creates a negative pressure which drags material along. The most common media used in our industry are water and air.
The water can be pressurized using a High-Pressure water pump and this creates a high-speed flow that creates the desired negative pressure. When using an air compressor, you will not reach the same high pressure as with a water pump, but in return the air expands leaving the ejector nozzle.
Suction ejectors are used to shorten suction time emptying large spaces holding sand, sludge, and other heavier material. They are also used to increase the possible lifting height. An ordinary compressor can lift material about 7 meters (25 ft), theoretically. Normally, the use of an ejector in combination with an air compressor, create a total lifting height of approx. 13 meters (45 ft) and up to 20 meters (65 ft) using pressurized water.
AquaTeq® has a variety of suction ejectors suitable for suction hoses 1 ¼” up to 4”.
See all standard versions here + our mini version.
Cleaning Nozzles with Ejector action/Ejectors
We at AquaTeq® have our patented cleaning nozzles with ejector action/ejectors; BL SWIPER® and SWEAGLE®. When the BL SWIPER® was introduced to the market, the efficiency of this cleaning nozzles revolutionized the industry with its ingenious design. The BL SWIPER® nozzle was originally conceived as an air ejector at low to medium water levels in the pipe. It quickly turned out that you could also clean pipes extremely efficient also at a high-water level by using higher pressures than the normal recommended operating pressure of 40 - 60 bar (600-900 PSI) at the BL SWIPER®.
BL SWIPER® has a big advantage compared to a "standard" ejector nozzle. A standard ejector nozzle has zero degrees on the water jets mounted inside an or alternative two pipes, which creates a good ejector action. The disadvantage is that none of the water jets can reach the sediment on the sides of the pipe, so this normally remains after cleaning.
BL SWIPER® is available in a variety of variants for pipe dimensions 100 – 1200 (1500) mm (4”-48” (60”)).
This year we launched SWEAGLE®. SWEAGLE® has three built-in "real" ejectors. It has drastically increased the efficiency of the cleaning nozzle used under water with as low pressure at the SWEAGLE® as 60 bar (900PSI) (for BL SWIPER® +100 Bar (+1500PSI)). SWEAGLE® also works with an elevated level of efficiency in "dry" pipes or pipes with low water level using the same low operating working pressure as in waterfilled pipes. The angle of the water jets also cleans the sides of the pipe. If you are interested in a demo - get in touch!
Thanks to the revolutionary external and internal design of booth the BL SWIPER® and SWEAGLE®, with extreme high efficiency, they are assisting many of our satisfied customers saving time, water and a lot of diesel. There are documented cases where diesel consumption has been reduced from 55 liters (15GPM) of diesel per hour to 35 liters (less than 10 GPM) per hour with increased efficiency! We are talking environmental considerations and BIG SAVINGS!
]]>Looking at the word efficiency in general, it’s usually explained by:
Efficiency - Taking care of a specific matter in the correct way, means doing it in the most preferable, quickest and cheapest manner possible. In other words, it’s all about finding the most productive way.
A positive aspect of doing things in a productive manner is that most often the burden on the environment will be reduced.
If we dive deep into the significance of the word efficiency when it comes to our industry, we would like to highlight three areas that can be directly improved at each individual pipe cleaning project.
WATER CONSUMPTION - Each cleaning nozzle use a certain number of liters per minute/ Gallons per minute, depending on the jet insert size set-up. The water consumption per minute will be less if the cleaning nozzle is set up for less liter per minute. But there are other essential areas that will affect the efficiency and the Total water consumption.
TIME - The number of passes a nozzle must do in the pipe to clean it requires time. It’s obvious to everyone that the result of having to do fewer passes means saving precious time. A cleaning nozzle that is more efficient but use more liter per minute will at the end save a lot of water totally since it needs fewer passes to clean the pipe.
In addition, each pass requires the creation of water under pressure and to do so, power must be extracted from an engine. Finally, there is a third area that we can influence which is:
DIESEL - To create water under pressure, a certain speed is required on the engine, which in turn, operate the water pump. The engine mostly consumes diesel. An average jetting truck consumes between 25-50 liters of diesel (7-13 GPM) per hour depending on its capacity and construction.,
But how do we reduce our consumption of valuable time, water and diesel?
The cleaning task is performed by the nozzle. The cleaning nozzle is the very key to reducing the consumption in all the three mentioned areas above. But how can we achieve this?
1. One of the most essential factors is to make sure that each nozzle used on the jetting truck is set up and adapted to the truck and its mission.
2. It’s of the outmost importance to use the correct cleaning nozzle for each individual job. All types of nozzles have their specific assigned areas of work, which means that it’s essential to choose the right nozzle for each task. A nozzle used for clogged pipes is not suitable, nor efficient, when it comes to cleaning a pipe from sand, gravel, sludge etc. A descaling nozzle should be used to remove deposits in pipes or, for example, finer roots. It’s not intended for moving large amount of material in pipe.
3. Work with the correct pressure. Different pipe cleaning nozzles each have their optimal working pressures, that is where they operate most efficient. Furthermore, the water flow should at this optimal working pressure, be adapted to the size of the pipe. It requires fewer liters per minute to clean a smaller pipe compared to a larger one. This is also something that should be considered when adapting the cleaning nozzles to the jetting truck.
If you use an efficient cleaning nozzle to remove material in pipe, it can be operating at a much lower pressure than if the assignment is to open clogged pipes, milling or descaling.
At AquaTeq® we possess an extensive knowledge of all our products and how they in the best way possible can be optimized for each jetting truck. We help our customers on a daily basis with streamlining their cleaning projects. This is done by making a thorough analysis of the most common cleaning assignments and in which pipe dimensions they are done. We equip both new and existing jetting units as well as providing advice and information on the best usage of each individual nozzle or cutter.
Class 2 or Tier 2 as it is called internationally is, as you know, a slightly simpler design inside the nozzle without internal control of the water in the chamber but with exchangeable jet inserts instead of simple drilled holes in the nozzle body. Then all Tier 2 nozzles should be equally good? That is certainly not the case. The inner chamber, jets, number of jets, angle of jets, size of the jets… There´s a lot of parameters that can make a big difference in the efficiency of a Tier 2 nozzle.
MULTI GLOBAL®, is one of the best Tier 2 nozzles on the market. It´s available in sizes from 3/8 "to 1-¼" hose thread connection and can be used for many different jobs and assignments. The short and round body makes it easier to get through bends and offsets.
Depending on the setup, you can use the nozzle for different projects, such as:
• Cleaning (pulling or moving materials) - Plug all four front jets and let all the water flow out the back. We recommend about 60 Bar (900PSI) at the nozzle for best results. A tip is to use an extender pipe to prevent it from going in to branches and prevent it from turning in the pipe.
• Universal nozzle, easier clogs - Equipped with three plugs in the front and just one front jet in the center, to open blockage. We put slightly smaller jets at the rear of the nozzle to let the nozzle run at higher pressure. We recommend at least 100 Bar (1450PSI) at the nozzle.
• Ice / heavier clogs - equipped with three jets in the front that are angled towards each other (as a focal point) and a plug in the center. The same principal as above, slightly smaller jet inserts are mounted at the rear to ensure the recommended pressure of at least 100 bar (1450 PSI).
• Cleaning before root cutting or difficult blockage - all four front jets and rear jets are used. By using a setup like this, we get a lot of water in many different angles that are effectively clean up rocks and gravel, paper, sludge, etc. that is stuck in the roots and makes the job difficult for the root cutter and creates unnecessary wear on the cutter. When we use this nozzle to open up a boring path, we use more water directed forward than normal because the propulsion on these occasions is not as important as it is generally shorter distances for nozzle to travel in pipe. Here we set up the nozzle to work at higher pressures, at least 100 bar (1450 PSI).
GOBLIN® GRENADE - If you prefer a heavier but still flexible class 2 / Tier 2 nozzle that is lying in the bottom of the pipe and is mainly used for moving material out of the pipes, we recommend our series GOBLIN® GRENADE, they are available with 1/8 "to 1" threads. The 1” can also be used for 1-1/4” hose with an adapter. Its high weight means that, in both smaller and larger pipes, it tends to tip down and avoid getting stuck. But as always, we recommend the use of an extender pipe whenever possible to minimize the risk of the nozzle turning or going into branch pipes etc.
It is mainly set up with only rear jets but can of course also be used supplied with a front jet for easier blockages. It is set up to work at a pressure around 60 Bar (900 PSI) at the nozzle.
]]>Regardless of the cleaning nozzle used, whether the nozzle is of poor design or a very efficient design, the cleaning effect increases with up to 50 % when nozzle is mounted on a sled (skid) or is lifted from the bottom with the help from a wear body. Efficiency increases and costs decreases by saving both water and diesel. In addition, the time required to clean each pipe, is reduced. Simple math!
Why does a cleaning nozzle operate much more effective when lifted from the bottom of the pipe? By lifting any cleaning nozzle up from pipe bottom the water jets travel further behind the nozzle. Longer and stronger water jets move debris faster and further by increasing the water velocity in pipe. All together this will result in more material moved in fewer passes. It may also decrease need of step cleaning. Longer water jets also distance the material in pipe further behind the cleaning nozzle, which minimize the risk of nozzle leaving material behind in pipe.
Lifting any cleaning nozzle from the bottom of the pipe using a sled or wear body also allow lower jet angles. More effective cleaning nozzles ‘(Tier 3 and Tier 4) are in most cases able to throw strong water jets all the way out to pipe wall, meaning no material is left behind, even in larger pipes. Lower jet angles increase the speed of the water in pipe more effective than nozzles with higher jet angles. Same physical laws as travelling to the moon. You will never reach the moon if the jet beam leaves the rocket at a high angle. Low jet angles also increase the thrusting capacity of the cleaning nozzle, saving time, water, and diesel.
Summary:
“Mounting any cleaning nozzle in a sled or in a wear body increases the cleaning effect by up to 50%, compared with same nozzle positioned at the bottom of the pipe.”
JAWS® cleaning nozzle should always be mounted in a sled, but also JAWS®RC, Grenades/Bombs, rotating nozzles* and slow rotating nozzles* are suitable for mounting in a sled.
* A sled for a rotating nozzle, fast or slow, should preferably be mounted behind the nozzle to avoid damaging the sled runners from the waterpower.
The developing part of the world have the privilege of having access to both clean water and toilets, but we can and will do much more to protect our water.
Unfortunately, there are still many who live by the motto "if you can´t see it, it does not exist “and flush rubbish down the toilet.
One might easily think that toilet paper is the same thing as kitchen paper, but it is not. Toilet paper is easily broken down, while kitchen paper takes much longer.
Another major problem is washcloths and wet wipes that do not break down, which causes major problems for treatment plants and pumping stations.
The only things to flush down the toilet are feces, urine and toilet paper - nothing else!
A simple but smart invention in our sewer system is the water trap that prevents bad smells, diseases, and vermin from passing through.
We at AquaTeq have previously written how to reduce the risk of blowing toilets. Learn more: https://aquateq.com/blogs/news/minimize-risk
]]>We therefore wanted to present this topic in our November Newsletter, considering we are, like it or not, entering the cold season with snow and ice in many countries. Below is some experience we would like to share that we have gathered through the years in the business.
To start with, it is important to use a cleaning hose with low friction on the outer layer, both when using hot and cold water to remove ice plugs. A good choice is Parker's 5-2605 (3/16”) and 5-2606 (¼").
The next thing to consider is what nozzle to use. Preferable for ice blockages is a nozzle that effectively open the ice and is properly balanced between the forward hydropower and the reverse thrusting power. The thrusting power needs be high to allow the nozzle to pull the hose up the line, especially when the distance to travel is long. To minimize the pressure drop in hose, it is more effective and resource saving, using a nozzle with less water consumption (LPM or GPM). The FIR® series is good alternative of a nozzle for ice blockages. The FIR® was developed in collaboration together with one of our customers, struggling with ice plugs and in need of a solution.
A small portable hose reel makes it is easy to store both the hose and nozzles. The design should be made to minimize the pressure drop when water is flowing through the reel. The reel is also easy for the operator to handle. All in one place.
If you use hot water for ice blockages, the water temperature should never exceed 35˚-40˚C (95˚- 105˚F). Water at higher temperatures freeze faster and once frozen the ice becomes harder.
When it comes to severe clogs in sewer pipes and stormwater pipes, most operators use the hose mounted onto the jetting truck, unless the pipe is very small, then a smaller hose normally is connected to feeder hose. The most common nozzle used for opening clogged pipes is a Chisel Nozzle.
Chisel nozzles are supplied with four front jets, meaning a high percentage of the used water flow rate are directed forward. The angles of the forward jets create a wide impact on the clog. This makes chisel pointed nozzles efficient on ice plugs and other clogs. The pyramid shape and length of the Chisel Nozzles may cause difficulties when needed to pass bends and joints in pipe. The usage of high volume of water directed forward also decrease the thrusting power of the nozzle. This prevents the nozzle to travel further in pipe. The GLOBAL™ ICEBEAR and MULTI-GLOBAL® series of nozzles are preferred working in pipes with bends, joints, and long distances. They pass efficiently through obstacles in pipe, due to their spherical shape. The balance between thrusting power and forward working force makes them travel farther in pipe. GLOBAL ™ ICEBEAR (Tier 1) series of nozzles are supplied with three front jets. MULTI-GLOBAL® (Tier 2), supplied with exchangeable jets, can be set up with up to four front jets. The front jets, on booth types of nozzles, have a design where the front jets have an intersection point ahead of the nozzle. This makes them extremely powerful also at breaking severe clogs. Booth the GLOBAL™ ICEBEAR and MULTI-GLOBAL® are made available in sizes from ¼” hose connection up to 1 ¼” hose connection
For severe clogs in larger pipe sizes (150-500mm/6”-20”), the FIR®POINTED and GLOBAL™ SP often are an effective choice. Booth these nozzles are Tier 2 nozzles.

]]>Tier 1 pipe cleaning nozzles was designed around 1950. Tier 1 types of nozzles are normally called standard or conventional nozzle and the thrusting jets are normally angled between 20-40 degrees from the cleaning hose inlet.
Tier 1 nozzles have no internal water conductive design, just a hollow chamber, and the jet outlet holes are drilled in the nozzle material. The turbulence in a Tier 1 nozzle creates a pressure drop in the nozzle of 35-55 %, the reason for the substantial drop is the that the water basically must turn on itself somewhere between 140-160 degrees in order to exit the nozzle.
Tier 1 nozzles are still very common, mainly because of the low purchase cost. They do have their place when it comes to simple and easy pipe cleaning, clogged pipes or when a smaller sized nozzle is the only option to enter a pipe.
Tier 2 pipe cleaning (storm, sewer) nozzles have no internal water conducting design but are equipped with replaceable jet orifices. Tier 2 types of nozzles are normally called standard nozzles.
The interior design of a Tier 2 nozzle is a hollow chamber, same as Tier 1. Correctly designed replaceable jet inserts improve the performance. With jet inserts of good design, the pressure drop in the nozzle is around 20-30%.
Tier 3 pipe cleaning nozzle was firstly designed by one of the founders of AquaTeq®, already 1973. He quickly realized the waste of lost energy by using a Tier 1 or Tier 2 nozzle and therefore designed the GOBLIN® series – the Tier 3 nozzle was born.
Tier 3 pipe cleaning (storm, sewer) nozzles have water-conducting designs and are equipped with replaceable jet orifices for easy adaptation to different pump capacities.
Tier 4
1983 The Swedish Environmental Protection Agency a granted money for a scientific test to set fort what was the important factors for cost efficient pipe cleaning. One of the founders of AquaTeq® was invited.
Pipes were built above ground. For each test the lines were filled with 400 kg sand, gravel and stones divided over the length of the pipe. Different nozzles were tested to determine the nozzle designs impact on cleaning time and total water consumption.
This was the first time the Tier 4 - AquaTeq® High-End design was introduced. The JAWS® was born.
AquaTeq® High-End cleaning nozzles have an advanced water inner conductive design, reducing turbulence inside the nozzle. Compared with Tier 3, Tier 4 - AquaTeq® High-End nozzles have double efficiency in terms of total water and fuel consumption and time spent cleaning the pipe.
The JAWS® nozzle has been the no. 1 cleaning nozzle worldwide for many years. The past 10-15 years we have added the JAWS®RC, BL SWIPER®, C-RAY®, MANTA® and will shortly introduce the SWEAGLE® in the Tier 4 group of nozzles.
]]>
In a pipe, there are often several service lines connected from housing, which are affected by the air flow created when cleaning a pipe. The result may be what we normally call the "blowing toilet effect" and in many cases, is due to the fact that the ventilation on the houses are too small in relation to the air created and pushed into the system when cleaning a main line.
To understand the relationship between pressure and flow in the cleaning nozzle and how it affects the exaction of the nozzle in pipe and the nozzles ability to effectively clean the pipe there are two main rules:
How does "blow toilet effect” occur and how is it prevented?
The first critical operation to push water out of the water locking system in toilets etc (blow toilets) occur when the nozzle is thrusted up the pipe. Then an overpressure occurs behind the nozzle. At the same time, the air currents increase around the nozzle, meaning that around a larger nozzle the airflow will be higher compare with a smaller nozzle.
To minimize the risk of blowing toilets, the following measures should be taken:
BL Swiper® is a series of nozzles that are advantageously chosen to reduce the problem of blowing toilets.
The so called “Antiblast” nozzles normally uses an extra ring of jets with a high angel to reduce the overpressure behind the nozzle and decrease the pressure in front of the nozzle, by creating a blocking wall of water for the air to pass. However, due to the high-angle jets, efficiency is poor and results instead of poorer cleaning efficiency and therefore becomes an expensive and ineffective solution.
Conclusion; Cleaning of pipes involves the understanding of cause and effect to be able to use the resources in a cost-effective manner.
