Wastewater treatment by ion exchange method: a review of past and recent researches

摘要

Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. Ion exchange can be a process of purification, separation and decontamination of aqueous or ion containing solutions. Ion exchange resins are used in wastewater treatment process plants to interchange one ion with another to fulfill the purpose of demineralization. In this assignment, we look at the working principle, equipment design, advantages and disadvantages, and industrial applications of ion exchange as a water pollution remediation technique.
