I would like to know the difference between biocides that used for cooling water system and washing water system in terms of types, functions and mechanisms, especially with Sulfate-reducing bacteria (SRB).
Cooling towers are closed systems and the quality of the water is usually high so you only need to prevent Bacteria from growing. In this case a bio-state can do best to protect ( CMIT/MIT for example).
For Wash Water you need to to reduce the bacteria count as the quality of the water is relatively lower , here you will need to use fast killers like THPS , Glutral , formaldehyde or benzalkonium chloride
