Cooling Water
Treatment

Our high-quality IVG-CT cooling water solution makes it easy for you as a water consumer to cool 100% chemical-free and circular.

Industrial Vortex Generator

To control microbiological growth, scale formation and metal corrosion, water in cooling towers must be treated. Three processes take place in the Industrial Vortex Generator: the crystallization of minerals, the removal of unbound gas such as micro bubbles, and fighting microbial growth by damaging the cell wall. Soluble forms of calcium (such as calcium (bi)carbonate) are converted to calcite and aragonite. The cavitation forces produce crystals that do not adhere to pipes, nozzles, heat exchangers or other surfaces.

  • Reduces viscosity by 12-20%
  • Improves heat transfer by 3-5% for optimal cooling

Spinning Disk Filtration

Spinning Disk Filtration continuously filters the cooling water is in a recirculation loop with a flow rate of 40-50 m3/hour. The SDF filters the water with fast rotating movements to keep the suspended particles in the cooling water as low as possible.

  • Improves the capacity of the UV-C reactor
  • Reduces the chance of microbiological growth

SDF removes abrasive particles from the water for a longer service life of materials and pumps, and prevents sedimentation and blockages in pipes and heat exchangers.

Ultra Violet Type C Radiation

Where water is used, biofilm can form. Fungi, yeasts and bacteria that live in biofilms pose a health and safety hazard. UV-C is invisible radiation with a wavelength between 100 and 280 nm. Rays of this wavelength damage the DNA of microorganisms. The UV-C light neutralizes the micro-organisms and prevents them from reproducing. This takes place in the recirculation circuit with a flow rate of 40-50 m3/hour.

PAthema DESinfect

In large cooling water systems it is necessary to introduce a disinfectant to the water, in addition to the IVG and UV-C. The PaDes system (PAthema DESinfect) disinfects water by electrolyzing it without adding chemicals. The treated water contains free chlorine produced from the chloride already present in the cooling water or in the form of table salt. This way we keep the pipes, exchangers and the cooling water basin free of contamination such as bacteria or biofilm. Salt electrolysis is based on the conversion of dissolved salt into temporary chlorine by means of a low voltage direct current. After the free chlorine has done its disinfecting work, it is converted back into dissolved chloride and oxygen.
