This kind of treatment removes pollutants (such as suspended solids, metals, emulsions and color) through chemical reactions of coagulation and flocculation. The objective of the chemical-physical treatment is to change the state of the pollutants in the water into a form easy to be separated. Chemical addition causes the clumping of the particulate pollutants (such as turbidity particles, emulsion agents, etc.) into larger particles. Inorganic sludge is easily separated from treatment water by a setting unit.   Beside the common chemicals as lime and aluminum & iron salts, TDFC proposes other products specific for the application and the wastewater to be treated. TDFC also designs Fenton oxidative treatment plants, with strong chemical degradation obtained through H 2 O 2.          << Back
