Drinking water networks

The cleaning and disinfection of drinking water networks

The inside cleaning and disinfecting of water-supply systems is a recurring problem of system operators. The mechanical and hydraulic solution used so far are usually not economic, time consuming and the achieved results are not always the best. The
Our hydro gel  technology  can remove the residues from the pipeline easily and it does this in a cost effective manner. This environmentally friendly method can be applied in drinking water -supply systems, since it does not contain any harmful materials. 

Our patented technology is based on a special gel made from food industry ingredients and equipment for gel delivery.

The gel developed by NanoCleanWorld is a water based gel, which does not contain any hazardous materials, and it is completely environmentally friendly. Thanks to these properties it can be safely used to clean water-supply pipelines. The gel – as an effect of the water pressure – travels all along the pipeline as a plug and fully takes the inside shape of the line. It can even collect residues from the remotest little cracks.

According to the job to be performed we can use different types of gels: “pushing gels” removes the rough wastes, “collector gels” on the other hand collects the loosened particles. During the process of cleaning we create “gel-trains”, where the individual “carriages” can perform different jobs.

The gel-trains are always assembled to fulfill the given tasks for example it can contain different viscosity and functional gels, disinfectants or such small devices, which can exactly map the underground pipeline system. Using this new high technology we can deliver a complex solution to maintenance issues, even in one simple step. The cleaning job employing the hydro-gel is very simple, extremely cost effective, we recommend it to all system operators!

All this without breaking the system and the pipe network!

What we recommend to use:

The gel does not push the impurities in front of it, but collects them due to its turbulent rotation. During the implementation, we connect our mobile devices to the pipeline network of the given factory unit. A 30-70 meter long gel train is introduced into the system, consisting of successive hydrogel and disinfectant sections. The gel train moves forward under the effect of water pressure.

Advantages of our technology are:


What can you do with the Hydro-Gel and with the connecting technology?

The Hydro-gel and the connected new, Hungarian high technology can mainly be used to mechanically clean water-supply systems. Using this new technology it is possible to complete the pipeline cleaning and system upkeep procedures in a simpler and more economical manner, compared to the known techniques. A number of other jobs can be achieved with the Hydro-Gel, see below for details.

What are the component of the Hydro-Gel?

The Hydro-Gel is made of harmless components, which are also used in food industry as additional material to various foods.

How does the Hydro-Gel cleans?

The Hydro-Gel rubs off and collects the residual materials from the pipes and from the inner walls of pipelines. The gel itself has a huge surface, so it can collect almost all residue. The collected wastes exit the system along with the gel.

What is a “gel-train”?

We use different property gels for different cleaning purposes. For example, high viscosity “pushing gels” rub off rough wastes, the more diluted “pick-up gels” collects more loose materials inside. Between individual “gel plugs” we can deliver disinfectants, this way we complete the mechanical cleaning and the disinfection is one step! The different types of gel plugs travel inside the pipelines like the carriages of a longer train, this is called a “gel-train”.

How long is a “gel-train”?

The setup of the “gel-train” is always done according to local circumstances and needs. The usual length of the “gel-train” is 30- 70m. (Please note, that the length of a single sponge plug is minimal compared to the gel, approx.. 1m long.)

How does the Hydro-Gel behave if it encounters a diameter narrowing?

The Hydro-Gel – thanks to its positive viscosity and elasticity properties – fills the available space completely, and therefore takes on the shape of the pipeline at all times. It does not gets stuck at corners, at narrowing diameters or at the location of devices (imagine a half closed gate valve, for example).

What kind of pipeline diameters can be cleaned with the Hydro-Gel?

The Hydro-Gel can be used with the usual diameters of drinking water-supply systems: from the small diameter service pipes to largescale, crawlable transmission lines. In case of the mostly occurring diameters of DN25-300 mm the operation is a routine, and plans need to be done in case of bigger diameters.

How do you control the Gel inside the system?

The gel advances due to the effect of water pressure, navigation is achieved using the existing valves.

How fast the Gel travels inside the system?

The gel travels with the same speed as the water, depending on the applied water pressure. This is usually 0,5-1 m/s.

Is there a problem if the Gel gets inside the users’ subsystem?

Randomly it can occur, that during the cleaning operation – despite the prior notification of the users – someone opens some taps and the gel gets inside the local service line. Since the Hydro-Gel does not contain any harmful materials, this will not cause any problems at the end-user, will not cause any jamming, and after the cleaning process the user only needs to let the gel through the tap, until there is clear water flowing.

Where can you deposit the used Gel, are there any wastes generated which must be treated?

Since the used gel does not contain any harmful materials, it can be ejected to a public sewer. After the cleaning process is finished the gel will break up into pieces, and will not cause any jamming in the sewer In case there is no sewer available, the gel can be ejected to an open ditch or to an appropriate neutral area. The gel will decay within a few days, without leaving any waste that needs further treatment.

Does Hydro-Gel removes limescale from the pipeline?

The Hydro-Gel can primarily remove the loose, adherent contaminations (sediment, bacterial layer). In case of strongly adhered limescale and other mineral secessions it is expedient to use high frequency cleaning methods. Using this method it is possible to remove these strongly adherent residues from industrial heat exchangers without major structural works. This way we can save time and money! 

Can you disinfect the system using the Hydro-Gel?

Yes, the disinfectant can be diluted into the Hydro-Gel material, but we suggest using nano-fluids to disinfect. The nano-fluids can be transmitted between gel plugs (in a gel-train), and it has a proved bactericidal effect.

What additional technologies can be combined with the Hydro-Gel technology?

The Hvdro-Gel can be combined with technologies other than the nano-fluids. 

Another new development is the Pig+Gel technology, which can be employed during video surveillance of the inside of pipelines. During this operation a special type of pig is being moved with the Hydro-Gel at a constant speed, in order to achieve the best video quality. This technology can be used to economically and successfully provide the inside surveillance of hydrocarbon pipelines also.

The push gel breaks down the deposits inside the piping and the disinfectant kills the various pathogens lurking beneath them. The pick-up gel adheres to the elements thus broken down. At the point of discharge, the train, together with the collected dirt, can be freely released into nature, where it decomposes into completely environmentally friendly elements in a few days.
