Electro deionization is one of the most advanced technologies for ion exchange. With this technology, (ultra) pure water can be produced continuously. Electro deionization plant is also known as EDI Plant in our industry. An EDI plant is used after reverse osmosis process for polishing of demineralized water to procure low levels of conductivity and silica. EDI is an alternative to a conventional mixed-bed polisher. The quality of the product from an EDI plant depends on the incoming feed water quality to the electrodeionization system. EDI technology is higher in demand wherever there is requirement of highly pure water. Power plants, pharmaceutical industries, manufacturing process, chemical and laboratory industries require this ultrapure water. EDI plants can be highly effective at these places and processes.
Flow rates of these plants are up to 60 m3/h. WATERTEC EDI Plants are offered as standard modules as well as custom-made as per customer requirements. EDI Plants with a capacity of 60 m3/h completely demineralized the water with a very low conductivity and silica acid content for producing boiler water for high pressure steam turbine. The pipe system for treated water is made in PP (Polypropylene) connected by welding and each takes around 15-20 minutes to make.
EDI plants include:
All components can be operated with a single controller.
WATERTEC EDI plants are in high demand because of their powerful assembly, high performance and trouble-free operation & installation. Electrodeionization is a continuous process with chemical-free regeneration, that is why the regeneration downtime is eliminated and storage and handling of acid and lye are avoided. These plants are space-saving because of very compact design. The plants offer highest quality, require low maintenance, and their operational reliability is very high. The WATERTEC EDI Plant is superior to a conventional mixed-bed deionization system both in ease of operation and maintenance. In addition, no chemicals are used for regeneration. The EDI Plants are modular, so they can be designed for various capacities and easily expanded when required.
EDI Plants come complete and are also skid mounted. All plants are tested before delivery. The main components included are:
Selection of a plant depends on application, water quality and water consumption. Our water experts are at your service to ensure the best customized solution.
