COAGULATOR Russian patent published in 1998 - IPC

FIELD: equipment for recovery of metals and other impurities from sewage, process solutions; may be used in metallurgical, chemical, food and other industries. SUBSTANCE: coagulator has body installed for rotation with branch pipe for supply of solution to be treated and purified water, drive support and base. Located inside coagulator coaxially to its body are cylindrical holders for loading of reagents. Coagulator body has guide on generating internal surface and holders have mating recess. Holder height is multiple to body length and holder diameter equals 0.96-0.97 of inner diameter of coagulator body. Solution after purification is supplied through branch pipe and is passed successively through all holders filled with reagents. Qualitative and quantitative composition of reagents in holders may be different depending on the quality of solution. In this event, a number of electrochemical and settling processes take place to transfer impurities from solution into solid precipitate. Purified water is fed for filtering. EFFECT: reduced working costs; accomplishment of purification process in one stage and in one apparatus. 2 cl, 2 dwg
