Abstract: This invention provides an improved composition and method for dispersing high molecular weight polymers and copolymers used as flocculants for water and waste treatment by using, in combination with the polymer, a nonionic surfactant to retard polymer solubility, soda ash, a chelant, and a filler.
Abstract: This invention provides an improved composition and method for dispersing high molecular weight flocculant polymers and copolymers used for water and waste treatment by the combination of the polymer with an inert additive and a bonding agent.
Abstract: The invention disclosed relates to a method for using a new improved composition for inhibiting or preventing accumulation of scale or the like on heating surfaces in an aqueous system. The present composition includes an acrylic polymer, a water-soluble chelant, and an organophosphonic acid and/or their water-soluble salts. In a preferred embodiment, the composition is composed of sodium polymethylacrylate, nitrilotriacetic acid and hydroxyethylidene diphosphonic acid as its water-soluble salts.
