Process water treatment
Process water safety during inspections
View future health department inspections with peace of mind. The hydrophysical water treatment technology of the VA-Hydro effectively removes microorganisms
from your piping system, keeps the water hygienically stable, and prevents recontamination.
Environmentally friendly and effective, the VA-Hydro removes legionella and biofilms from water supply systems.
NO CHEMICALS - NO ENVIRONMENTAL POLLUTION
Cooling and process water treatment
Biological contamination in cooling installations is prevented by the hydrophysically treated water of the VA-Hydro. Biofilms in the pipelines are broken down and subsequent algae and
algae and biofilm growth is prevented. The cleaning effort is reduced, and costs for biocides are saved.
Industrial cleaning systems
The treated, soft water of VA-Hydro improves the washing and cleaning performance of industrial applications of all kinds. Organic contaminations and odour formations are effectively
eliminated. Cleaning costs and the use of detergents can be significantly reduced, and the service life of alkaline solutions, cooling lubricant emulsions and cleaning baths can be
Fire fighting water tanks and sprinkler systems
Fire fighting water tanks and sprinkler systems mostly use external water, which may contain microorganisms such as Legionella. The treated water of VA-Hydro frees the pipes of sprinkler
systems from these microorganisms. In addition, faster and deeper absorption into fire sources is made possible due to the reduced surface tension of the treated water.
Swimming- and hot pools, sports facilities
The VA-Hydro gives you the security and prevention of a legionella-free hot water supply in wet and shower areas. In the event of a seasonal shutdown or a specific case, such as the
Corona pandemic, there is no legionella risk in unused mains or pipes, thanks to the VA-Hydro.
Irrigation systems and ornamental fountains
In irrigation systems and ornamental fountains, the VA-Hydro reduces unsightly algae infestation. In addition, it prevents encrustations and odour problems caused by bacteria and moulds.
New infestation due to organic contamination no longer occurs thanks to the hygienically stable water from the VA-Hydro. Additionally your cleaning effort is significantly reduced since
only treated water flows through the piping system.
Easy installation and high quality materials
You can quickly and easily retrofit the VA-Hydro into existing infrastructures and circulation lines. Depending on specific water volumes and applications, there is a suitable VA-Hydro
system. A performance overview of the VA-Hydro systems can be found in the respective datasheet. All water-bearing components installed in the VA-Hydro are made of materials tested
according to DIN 1.4571. The materials comply with DVGW requirements and are suitable for installation in drinking water and cooling water systems.

The VA-Hydro ensures operational sanitary safety without biocide (chemical)
use, only through hydrophysical functionality when used in process water installations and circulation pipes.
Application sample of the VA-HYDRO
Symbolic illustration in a cooling water system
The heart of the VA-Hydro is similar to a cyclone. In the chamber, water is extremely accelerated so that very high flow and cavitation forces are generated, which mechanically destroy bacteria.
2. Cooling tower
The VA-Hydro keeps process water in cooling towers and heat exchangers free of microbiological contamination and hygienically stable. Existing infestation and insulating biofilm coatings are
successively broken down, lowering your operating costs and reducing your maintenance effort.
3. Collection Tank
The VA-Hydro is integrated into existing water circuits for cooling water or hot water circulations. If this is not possible, a separate treatment circuit must be created via a collection tank.
4. Pressure boosting
A high-pressure pump feeds water into the reaction chamber of the VA-Hydro to make optimum use of the hydrophysical water treatment effect.
5. LEGIONELLa colonies
One effect of hydrophysical water treatment with the VA-Hydro is reducing the surface tension of the water by up to 40 %. The water infiltrates and dissolves biofilm deposits (which contain
legionella colonies) to destroy them in the reactor chamber after that.
Without the addition of chemicals, the cell walls of for example e.g. legionella, are broken down in the water. The microbiological matter is mechanically destroyed. Oxygen dissolved in the water
subsequently oxidize the mechanically destroyed cell material.
7. Branch lines
Due to a lack of flushing processes, unused pipes and branch lines are an ideal breeding ground for legionella. Such branch lines can also be flushed with the VA-Hydro to remove legionella
from them to counteract this.
Requirements and certification
All valves and seals used in the VA-Hydro are approved for drinking water and comply with the DVGW (German Gas and Water Association) requirements according
to DVGW W 270. Since there are no moving parts in the VA-Hydro, and it only works with the shear forces known from nature (cavitation principle), no lubricants or preservatives are used.
The VA-Hydro system does not endanger or impair drinking water, according to DIN EN 1717. Thus the application of the VA-Hydro corresponds to category 1 according to DIN EN 1717 .
