Overview of Electrodeionization (EDI)
An EDI plant is designed to produce high-grade demineralized water with low conductivity, potentially reaching as low as 0.06 µS/cm, given proper pretreatment. This system offers continuous operation without the need for chemical regeneration, eliminating downtime and the need for handling acids and lyes. The compact design of EDI systems also removes the necessity for large chemical storage tanks.

Applications
The EDI system is typically used after reverse osmosis (RO) to further polish demineralized water, reducing conductivity, silica, and total organic carbons (TOC). It employs ion exchange membranes, resins, and electricity to achieve high-quality water without regeneration downtime. Key customer groups include heat and power plants, the pharmaceutical industry, electronics industry, hospitals, laboratories, and the chemical industry.

Specifications
The document provides detailed specifications for various EDI models, including flow rates ranging from 125 to 10,200 liters per hour. Standard connections are made using PVC, and the frame dimensions are consistent across models, with variations in inlet, outlet, and drain sizes. The dimensions for all models are 800 mm in width, 1880 mm in height, with depth varying between 500 mm and 1200 mm depending on the model.
