What Is Polyaspartic Acid (PASP)? Green Scale Inhibitor
Polyaspartic acid (PASP) is a biodegradable, phosphorus-free polymer used as a green scale and corrosion inhibitor and dispersant for calcium carbonate, sulfate and phosphate scale in cooling water, RO and oilfield systems.
Properties
PASP is readily biodegradable, non-phosphorus and non-nitrogen-polluting, effective over a wide temperature and pH range, and also works as a fertilizer-efficiency and scale-control agent in agriculture.
Uses
Green cooling-water and RO antiscalant, oilfield scale control, and where discharge limits restrict phosphonates. Pairs with PESA for phosphorus-free programs.
Frequently asked questions
What is PASP used for?
As a biodegradable, phosphorus-free scale and corrosion inhibitor and dispersant in cooling water, RO and oilfield systems.
Is polyaspartic acid environmentally friendly?
Yes — PASP is readily biodegradable and phosphorus-free, making it a 'green' alternative to phosphonate antiscalants.
