Electro deionization is a process that deionizes water through applied current. It effectively removes dissolved inorganic matter. It is widely used in pharmaceutical industries or where <1 PPM TDS is required. EDI doesn’t require chemical regeneration, so there is no need to shut down the plant during regeneration. This helps to reduce operation costs. Feedwater limiting conditions are strict in the case of EDI, so only RO or DM treated water must be used as feedwater for this process. This makes electro deionization water treatment systems ideal for high-purity applications.
