FAQ Section
Is PESA considered a "Green" water treatment chemical?
Yes, absolutely. PESA is a phosphorus-free and nitrogen-free scale and corrosion inhibitor. It is highly biodegradable, making it the ideal choice for cooling water systems located in environmentally sensitive areas or regions with strict Total Phosphorus (TP) discharge regulations.
Under what water conditions does PESA perform best?
PESA excels in conditions of high alkalinity, high hardness, and high pH. Unlike traditional phosphonates, it maintains excellent scale inhibition (especially against Calcium Carbonate) even when the water concentration cycles are high, reducing water discharge.
Can PESA be mixed with other chemicals for a formulation?
Yes, PESA showcases a strong synergistic effect when compounded with phosphonates like PBTCA or HEDP. When used in a formulation, it enhances the overall scale inhibition performance and allows for a reduction in total chemical dosage, offering a cost-effective solution for industrial cooling water systems.
How stable is PESA in the presence of Chlorine?
PESA has good compatibility with chlorine and other oxidizing biocides. Unlike some polymers that degrade quickly upon contact with chlorine, PESA maintains its structural integrity and performance, ensuring continuous protection of your system.
