METHOD OF AND DEVICE FOR EXTRACTION OF SILVER FROM WASTE WATER

摘要

FIELD: chemical and photographic industry; reclamation of silver. SUBSTANCE: waste waters are treated simultaneously by constant magnetic field and infralow frequency pulsed magnetic field with subsequent settling and separation of sediment. Treatment is carried out at continuous circulation of one and the same amount of water. For this purpose device with housing with inlet and outlet branch pipes is furnished with anode and cathodes installed for rotation. Device has also constant magnetic field system with permanent magnets and infralow frequency pulsed magnetic field system with corresponding generator and coil coupled with generator and installed on perimeter of housing. Inlet and outlet branch pipes are interconnected by pipeline in which pump is installed. permanent magnets are installed on cathodes, housing and above-indicated pipeline. EFFECT: reduced time of settling, improved conditions of separation of phases, increased capacity at reclamation of silver. 1 dwg
