The primary purpose of using poly-electrolytes in the pre-treatment stage of a desalination plant is to enhance the coagulation and flocculation processes, which are crucial for removing suspended solids and colloidal particles from the feed water. Coagulation is the process of destabilizing these fine particles, allowing them to begin clumping together. These particles often have a negative surface charge, which prevents them from aggregating and settling out of the water. Poly-electrolytes are ....
