The product is made of bentonite and organic/inorganic modifier. It has swelling property, ion exchange ability and absorption capacity and so on. The modification of bentonite makes its carbon content increased, improves hydrophobic properties and the ability of organisms removal. Inorganic modifier transforms the mineral single crystal into associative structure in column and leads to a larger space among particles, which changes the dispersion state and properties of bentonite in water and improves the ability of absorption, ion exchange and integration. Usage This product is used for the advanced treatment on heavy metal wastewater (mainly in the industry of electrolysis, electroplating, metal mines, smeltling and so on). WP206 Powder is used with gap method adsorption process. The rational dosage is two to six times amount of heavy metal. Stir and disperse for 10 to 30 minutes. Frame filter and centrifuge can be used as separation equipment, and may be settled in sedimentation pool. The waste mud could be used in raw mix and clinker in cement production, or let professional solid waste companies to handle it.
