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.

Our process water treatment plant can combine various technology, depending on the purity required:

Source Quality required Technology applied
500-2000 uS/cm 5-20 uS/cm Reverse Osmosis
< 5 uS/cm 2-pass reverse Osmosis
< 1 uS/cm 2-pass reverse Osmosis + Mixed bed
< 500 uS/cm < 5 uS/cm Ion exchange
< 1 uS/cm Ion exchange + Mixed bed

Once demineralised, process water should be conditionned according to manufacturer's specification, usually up to pH 9 by adding caustic soda or ammonia.

More information on demineralised water

Further demineralisation is also possible to obtain ultra-pure water quality
