METHOD AND SYSTEM FOR REVERSE OSMOSIS DEHYDRATION OF CONCENTRATE DURING TREATMENT OF WATER FLOWS Russian patent published in 2025 - IPC B01D61/02 B01D61/08 B01D61/58 C02F1/44 

FIELD: water treatment.

SUBSTANCE: present group of inventions relates to a method and a system for reverse-osmosis dehydration of a concentrate when treating water streams. Method consists in the formation of a number of successive cycles, to the first of which source water is supplied, obtaining at the output of the cycle a permeate and a concentrate, wherein the permeate of each cycle is sent to the consumer, and the concentrate from each previous cycle is sent for processing in the next cycle, wherein process of cyclic water treatment on each of successive cycles includes using a separate reverse osmosis filter unit on each cycle, pressure at inlet of which in each cycle increases to a level providing effect on hydrate complexes with higher energy than hydration energy, wherein process is repeated until such number of successive cycles, until flow of permeate through reverse osmosis filter element on corresponding cycle stops, then, after absence of permeate consumption is recorded at appropriate cycle, it is considered to be the last one to direct dewatered concentrate from the last cycle for disposal. System comprises a number of series-connected modules (M₁…M_n) for cyclic treatment of a water stream, where each module (M₁…M_n) for cyclic treatment of water flow includes pipeline circuit (1) with shutoff and control (2) and measuring equipment (3) providing the fluid flows in the circuit and at its outlet complex control, reverse osmosis filtering unit (4), fluid medium accumulators (5), High-pressure pump (6) generates pressure at inlet of reverse osmosis filtration unit sufficient for reverse osmosis process.

EFFECT: high degree of purity of source water.
