PESA Zero Phosphorus Biodegradable Antiscalant

 PESA Polyepoxysuccinic Acid is a fully biodegradable zero-phosphorus green scale inhibitor, which is the mainstream replacement product of traditional phosphorus-based scale inhibitors for enterprises carrying out phosphorus-free water system transformation. Since the molecular structure does not contain any phosphorus element, it completely eliminates the risk of excessive total phosphorus in wastewater discharge, and enterprises do not need to invest additional phosphorus removal equipment to meet environmental standards. The multi-carboxyl molecular structure of PESA has excellent chelating capacity for calcium and magnesium hardness ions, and its scale inhibition performance against calcium carbonate and calcium sulfate is close to mainstream organic phosphonates, with ultra-high calcium tolerance suitable for high-hardness raw water. It has mild auxiliary corrosion inhibition performance, and can form a better composite protection system when matched with azole metal corrosion inhibitors such as BTA and TTA. PESA can be completely degraded by microorganisms in water without residual accumulation and secondary pollution to water environment, which meets the production standards of green factories and zero-discharge industrial parks. It is widely applicable to food processing workshops, photovoltaic production lines, municipal reclaimed water recycling systems, reverse osmosis pure water equipment and closed circulating cooling water. By choosing PESA to build a full phosphorus-free water treatment system, enterprises can get rid of the strict supervision of phosphorus emission indicators, smoothly pass environmental assessment and green factory certification, and realize sustainable recycling of industrial water resources.
