PESA is a multivariate scale and corrosion inhibitor without phosphor or nitrogen, it has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride and silica scale. Compared to ordinary organophosphines, it has better effects. When it is compounded with organophosphates, the synergism effects are obvious.
PESA has good biodegradation properties, it can be widely used in circulating cooling water system of high alkalinity, high hardness and high pH value. PESA can be operated under high cycles of concentration. PESA has good synergism with chlorine and other water treatment chemicals.
