Belgian separations technology company PuriTech announces IONEX, an ion exchange system based on a new rotating multi-port valve. The liquid adsorption separation technology improves liquid-resin contact efficiency while reducing plant operating costs and capital expenditure. It uses a single, multi-port distribution valve, creating a process system for continuous, countercurrent ion exchange. The patented valve distributes different flow streams to several resin cells and determines whether the resin is in an adsorption, regeneration or rinsing cycle. The process disk within the valve rotates around a central axis and distributes the different flow streams to the cells containing ion exchange resin or other adsorption materials. During a full rotation, each cell is subjected to an entire sorption cycle.www.puritech.be
