FLUID CLEANING SYSTEM Russian patent published in 2017 - IPC C02F1/00 B01D36/00 

FIELD: wastewater treatment plants.

SUBSTANCE: invention relates to fluid purification systems, preferably water, used in domestic and/or potable water supply in household and/or industrial conditions, on suburban and garden plots. Fluid purification system comprises initial fluid source, purified fluid supply line to consumer, liquid purification unit, including liquid-liquid type container, consisting of housing and device, forming cleaned fluid collection chamber and displacement cavity, located inside housing, at least one liquid cleaning device, drain line and fluid flows control system, including initial fluid supply unit and purified liquid supply unit. In liquid cleaning unit fluid flows control system is made with initial fluid distribution unit with possibility to maintain fluid pressure in displacement cavity, preferably, for initial liquid container higher, than atmospheric pressure. Initial fluid distribution unit is made according to fluid motion counter-flow scheme and comprises initial fluid re-circulation line, connected at one end to displacement cavity for container initial fluid and at other end is with initial fluid source and initial fluid supply unit. Either initial fluid distribution unit is made according to two-track scheme in form of initial fluid inflow line into displacement cavity for container initial liquid, at inlet connected to initial liquid source, and at outlet is with displacement cavity for initial liquid container, and initial fluid displacement line from container displacement cavity, connected at inlet to container displacement cavity and at outlet is with initial fluid supply unit.

EFFECT: technical result is improving fluid cleaning system reliability and simplifying its design while improving its operating properties, including provision of cleaned liquid supply to consumer at any moment of fluid treatment process and after its completion.
