What Is Polyelectrolyte Membranes?

Polyelectrolyte membranes used as a separator in the VRFB have the important task of separating efficiently the half cells and conducting anions or protons to equilibrate the ionic strength during the charge and discharge procedures.

What is the purpose of polyelectrolyte?

They are thus often used as thickeners, emulsifiers, conditioners, clarifying agents, and even drag reducers. They are used in water treatment and for oil recovery. Many soaps, shampoos, and cosmetics incorporate polyelectrolytes. Furthermore, they are added to many foods and to concrete mixtures (superplasticizer).

Why is polyelectrolyte used in water treatment?

The main applications of organic polyelectrolytes in potable water production are in coagulation and flocculation, and in the dewatering of treatment plant sludges. ... Polymers have been utilised in coagulation/flocculation processes for water purification for at least four decades (Kawamura, 1976).
