METHOD OF PURIFYING WASTE WATER FROM HEAVY METAL CATIONS Russian patent published in 2014 - IPC C02F1/48 C02F1/62

Abstract RU 2504518 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in treating electroplating wastes. The method of purifying waste water from heavy metal cations with a low-frequency pulsed field involves treatment in a heterogeneous medium formed by at least 12 mmol/l of calcium hydroxide, in an electromagnetic apparatus using energy of an alternating electromagnetic field formed by magnetic elements made of hard-magnetic material moving under the effect of said field.

EFFECT: invention increases efficiency of purification from heavy metal cations and cuts the duration of treatment.
