SETTLEMENT WATER SUPPLY SYSTEM WITH PHYSICAL-CHEMICAL TREATMENT WORKS Russian patent published in 2012 - IPC C02F9/14 

FIELD: process engineering.

SUBSTANCE: invention relates treatment and decontamination of whatever effluents and may be used in treatment plants of minor settlements, cottages and camps, educational and medical centers, etc. Proposed system comprises settler with thin-layer modules, high-rate trickling filter with granular packing, plasma chemical reactor with HV pulse generator with pulse repetition frequency of 0.1-0.2 Hz, wells communicated with pipelines, manifolds and sewage pump station, grids, sand trap, catalytic electrochemical reactor, biological pond with compressor and botanical site with higher aquatic vegetation, clean water pump station, manifolds to feed cleaned water into filtration trenches. Catalytic electrochemical reactor is composed of standard high-rate trickling filter with distribution and collection system. Filter packing represents alternating and screen-isolated electrically negative granulated material, for example, manganese-alumina catalyst AOK-7541 and electrically positive carbon-bearing granulated material, for example, active carbon AC-3.

EFFECT: closed-circuit nonpolluting water supply system, reduced power consumption.
