Maximum chlorides in cooling water
As part of an existing cooling water system we have a number of equipment made of carbon steel, SS304L and SS316 that has been passivated. Biocides, algaecides and chlorine are some on the chemicals added at the cooling tower for water treatment purposes. Due to high levels of chlorides on make up water we have to purge huge amounts to operate bellow 200 ppm chlorides at 45°C max. and pH 7.3-7.5.
Could you let me know if we can operate above 200 ppm chlorides taken into account our material spec.?

Yes, you can operate up to 250 ppm chlorides depending upon your passivation chemicals/treatment. On further information on passivation treatment process, parameters can be told.ANJUM SHARIF
