<p>A water treatment process subjects raw water, for instance in a recirculating heat exchange, for instance cooling, system sequentially and immediately to an ion exchange step of a biocide step, the biocide step involving treatment in an electrochemical reactor. The biocide step contacts ion exchange water with a pair of electrodes in the presence of a catalyst, for instance platinum. The process provides efficient avoidance of microorganism build-up and minimises regeneration times. Water flows through inlet (1) downwards through a bed of ion exchange resin in ion exchange unit (2), directly into electrochemical reactor (3) comprising alternating corrugated anodes and cathodes connected by d.c. power supply (4) and out of outlet (5).</p> |
