Process water treatment - Manufacturing, Other
Process water covers the wide range of boiler feed water, cooling water for heat exchangers or engine, chemicals dilution, etc. It should typically have a conductivity ranging from 0,1 to 50 uS/cm, with little to no hardness to avoid scaling in heating system. Oxygen and carbon dioxide should be removed to prevent corrosion. Depending on your application, the water quality requirements can vary: Boiler feed water characteristic. Cooling water quality. Tap water or fresh groundwater are the most widely used source of water to produce process water.
Once demineralised, process water should be conditionned according to manufacturer's specification, usually up to pH 9 by adding caustic soda or ammonia.
