COMPOSITION FOR WASTEWATER PURIFICATION Russian patent published in 2012 - IPC C02F1/28 C02F1/52 B01J20/20 C02F103/16 

FIELD: chemistry.

SUBSTANCE: composition of wastewater purification includes sorbent, coagulant based on chlorides of iron, aluminium, mineral complex based on alkaline ashes and polyakryl amide. Content of mixture of oxides of alkali earth metals CaO+MgO in mineral complex constitutes not less than 40%. As sorbent used is oxidised or extended crystalline or cryptocrystalline graphite with the following content of components in composition, wt %: sorbent 10-20, coagulant 15-30, polyakrylamide 1-5, mineral complex based on alkaline ashes - the remaining part. In preferable version of composition ratio of mixture of alkali earth metals CaO and MgO in mineral complex constitutes 3:1.

EFFECT: increased efficiency of wastewater purification.
