Solid wastes water-soluble polymers

Cationic monomers are used to enhance adsorption on waste solids and facilitate flocculation. One of the first used in water treatment processes (5) is obtained by the cyclization of dimethyldiallylammonium chloride in 60-70 wt % aqueous solution. Another cationic water-soluble polymer, poly(dimethylamme-co-epichlorohydrin). prepared by the step-growth...

Silicones find practical application in different membrane unit operations for treating gaseous and liquid mixtures. This is due to their solubility controlled transport, which allows the selective separation of organics from air or from water. Polymer blending, polymer grafting, addition of different solid fillers or ionic Hquids, are the most effective strategies for improving the stabihty as well as the selective transport of silicones. The industrial applications of silicone-based membrane systems present environmental benefits such as reduced waste and recovered/recycled valuable raw materials that are currently lost to fuel or to the flares.
