TP25-06 Advancements in the DevelopmentThe scale and corrosion inhibition programs for industrial cooling water systems have relied on inorganic phosphate, organophosphate, zinc, and azole based chemistries for decades. Traditionally, organophosphate based chemistries are dosed as scale inhibitors along with phosphate based corrosion control programs. The phosphate based cooling water treatment programs replaced chromate and zinc based corrosion inhibitors for mild steel and stainless
