Abstract
The problems of improving the hardware design and increasing the efficiency of neutralization stations for wastewater of galvanic production related to the combination of methods of galvanocoagulation and intensive hydromechanical separation of ferritic suspension using new modifications of flow-through apparatuses of precipitation and filtering types developed by MSUIE: two-stage hydrocyclone modules and centrifugal microfiltration unit are considered. The method of microfiltration with the flow of separated suspension over the membrane has recently been widely used in deep water treatment at various environmental facilities. As applied to the hapivan-coagulation technology of waste water decontamination, flow-through microfiltration at the finishing stage also provides additional purification of water from low-concentrated dissolved contaminants.
