Application of polyelectrolytes obtained by radiation processing to potable and waste water treatment

Comparative results obtained by using classical treatment with electrolytes and combined treatment with electrolytes and polyelectrolytes (acrylamide copolymers) for potable water and waste water from vegetable oil plants and slaughter houses are presented. The polyelectrolytes used are obtained by combined electron beam and microwave-induced polymerization. They are available in a wide range of molecular weights and charge densities as well as with very low residual monomer content (under 0.02%).
