Pristine Water Electrolytic Scale Removal system is a chemical  free scale removal system that not just descales the heat exchangers of any cooling water circuit but also simultaneously disinfects the water so that algae, bio Fouling, and growth of microorganisms is prevented.

Electrolytically removing scale involves developing an environment of high pH around the cathode, the reaction is as follows:

2H2O + 2e → H2 ↑­+ 2OH

O2 + 2H2O + 4e → 4OH

The calcium hardness precipitates in the form of CaCO3 and of the magnesium hardness precipitates in the form of Mg(OH)2 in an alkaline environment.Ca2+ + HCO3 + OH → CaCO3↓  H2O

Mg2+ + 2OH→Mg (OH)2 ↓

In addition to the above reactions, the chloride ions if present in the water will get converted to active chlorine at the anode.

2Cl→Cl2 ­↑+ 2e

The introduction of hydroxyl ion (caustic) to recirculating cooling water results in conversion of bicarbonate to carbonate, fostering calcium carbonate precipitation. Electrolysis can provide the caustic to promote precipitation, capture, retention and removal mechanisms necessary to create a fully functional treatment strategy.

Pristine Water has designed and manufactured an Electrolytic Scale Removal System which provides a proper environment for not only capture and fixation of calcium and but also produce required chlorine from the chloride present in the water. All this is done in a simple, easy-to-maintain system without the requirement of chemical introduction or handling.

The system can be installed in the existing cooling water pipework without any major modification.

The system are most of the time installed as an side stream descaling arrangement.
