This study presents an ion exchange unit designed for selective and comprehensive
wastewater treatment. The unit includes all technological processes: solution filtration, ion exchanger
loosening, sorbent regeneration and washing, which is a significant advantage of the proposed
technology and eliminates the need for additional devices. This significantly increases the overall
efficiency of the cleaning process, reducing costs and simplifying the operation of the system.
Experimental studies have confirmed the high efficiency and feasibility of using ion exchange units in
modern operating conditions, which makes them universal in application for various industries,
including metallurgy and chemistry. The main idea of the invention is to create domestic equipment
that provides high efficiency of wastewater treatment with minimal costs and a simplified design.
