Optimized Polymeric Membranes for Water Treatment ... - MDPI

Conventional polymers, endowed with specific functionalities, are extensively utilized for filtering and extracting a diverse set of chemicals, notably metals, from solutions. The main structure of a polymer is an integral part for designing an efficient separating system. However, its chemical functionality further contributes to the selectivity, fabrication process, and resulting product

Role of Polyelectrolytes in the Treatment of Water and

Natural non-ionic polyelectrolytes are starch, cellulose derivatives, gelatins and glues. Their structure, molecular weight, biodegradability and ease of dissolution are found to be different. Synthetic polyelectrolyte namely non-ionic PAM has also been used in water treatment (Selvapathy and Reddy 1992 ).

polyelectrolyte treatment - an approach for water quality

POLYELECTROLYTE TREATMENT - AN APPROACH FOR WATER QUALITY

These phenomena of coagulation and flocculation are effectively dealt with by the use of organic polymers called polyelectrolytes. The spectacular contribution of the polyelectrolyte family of compounds in raw water treatment programmes overcomes the various operational difficulties imposed by metal coagulants such as alum or aluminium sulphate.

Addressing water scarcity: cationic polyelectrolytes in water

Polymers for flocculation and coagulation in water treatment are water soluble to allow interactions with impurities. Depending on solvent and pH, the positively charged moiety and anionic counterions dissociate, thus enabling the polymer backbone to repel itself, adopting a ridged-rod conformation and allowing interactions with other
