Electrodeionization, referred to as EDI, also known as the continuous electrolytic desalination technology, which scientifically the integration of electrodialysis and ion exchange technology, through the choice of anion and cation through the role of ion exchange resin and the exchange of water ions , Under the action of the electric field to achieve the directional migration of ions in the water to achieve the depth of water purifying desalination and hydrogenation of water through the electrolysis of hydrogen ions and hydroxyl ions on the resin for continuous regeneration resin, , Alkaline chemical regeneration can be continuously made of high quality ultrapure water, it has the advantages of advanced technology, compact structure, easy operation, can be widely used in electric power, electronics, pharmaceuticals, chemicals, food and laboratory areas, water treatment Green revolution in technology. The utility model is characterized in that the electrodialysis technology and the ion exchange technology are ingeniously integrated, and the high-quality pure water is continuously prepared without acid and alkali. The emergence of EDI is a revolutionary progress in water treatment technology, marking the water treatment industry eventually fully into the ranks of the green industry. EDI features 1. Sustainable production of qualified ultra-pure water in line with user requirements, water stability 2. No chemicals for regeneration, no chemical emissions 3. Compact structure, small footprint, low cost of water debugging device debugging before leaving the factory, on-site installation and commissioning simple 4. Operation is simple, low labor intensity, easy to train EDI unique 1. Unique advanced structure, smooth flow path, pressure drop 2. Fully enclosed design, completely eliminate leakage, routine maintenance, easy maintenance Special material shell, good insulation, lightweight and beautiful, easy to change 3. Unique components and membrane shell detachable structure, easy replacement of resin and components 4. Wider water index, more adaptable 5. Modular combination, easy to adjust the system water 6. Low operating voltage, low energy consumption Ultra-pure water to remove a deep layer of salt water, so that the purity of water increased. Treatment system uses booster pump, UV sterilizer, microporous filter, EDI device, pure Water Tank, pure water pump, polishing mixed bed, terminal filter. EDI device is the application of reverse osmosis system, instead of mixing ion exchange bed mature technology with stable quality of water production, low operating costs, easy operation and management. Small footprint and no harmful waste water emissions and other advantages. The development direction of ultrapure water preparation technology has been adopted by major water treatment engineering companies all over the world. Especially in the pharmaceutical, semiconductor, power and optoelectronics industries have been very widely used. EDI pure water equipment advantages Overall there are six advantages: ①do not need acid-base regeneration; ② continuous production: ③ do not need to deal with waste acid and alkali; ④ low operating costs; ⑤ system design and installation is simple; ⑥ water quality and stability. Polymer Concrete Cells For ER/EW Processing Of Nonferrous
Long-term impermeability, free of corrosion, 20+ years warranty
The structural core of electrolytic cells is bolstered with sturdy external seismic reinforcement blocks confining its floor supports, and includes a robust, internal bidirectional, pultruded FRP bar mesh reinforcement which positively maintains integrity should the cell fail due to catastrophic events. Electrolytic cell installation protocols call for lateral wall collaboration between cells,thus reducing stress levels of cell around 40% under normal operating conditions.

Electrolytic cells are designed, built and installed to satisfy the most stringent requirements requested by tankhouse operators worldwide. In most cases their main request is to guarantee full operating availability throughout the plant's lifespan, maximizing production of high-purity metal (copper, zinc, nickel, cobalt, lead or other nonferrous metals) with absolute safety for people and the environment. Additionally, cells must accommodate changes for continuous improvement of the electrolytic process, integrating efficiently with upgrades of complementary equipment such as anodes, cathodes, cap, boards, overhead crane electrolyte agitation systems, acid mist control devices, thermal insulation among many others.
The Internal layer is a monolithic tank made with multiple layers of fiber-reinforced vinyl ester resin (FRP) complying with chemical barrier international norms that assure long-term impermeability and corrosion resistance.
The Intermediate layer is the structural core made with polymer Concrete, with a patented formulation to achieve a low coefficient of thermal expansion, providing long-term structural integrity with low thermally-induced stresses
The External layer is a standard seal layer of FRP that further protects the structural core from electrolyte splashes and spills. Optionally,this external seal may be specified with multi-layered oriented fiber reinforcements to guarantee trouble-free operation in unusually extreme operating environments.
Benefits of electrolytic cells
Our monolithic internal tank manufactured with multiple layers of fiber-reinforced premium vinyl ester resin. It has continuous service without leakage, free of corrosion and structural flaws which operating under normal conditions as specified for each project.
Swift, accurate and less costly installation
Electrolytic cells include features that allow reduction of 25% or more in time needed for cell erection, alignment and leveling compared to time required with conventional polymer concrete cells. Dimension tolerances for electrolytic cells are consistently tight, simplifying installation in the most demanding applications,including plants with automated crane systems.
Minimum cleaning time and water consumption
The rounded internal shape,optional sloped cell floors,and smooth,flat finish of the internal tank,facilitate water sweeping and drainage of heavy sludge,with reduced water usage and accelerating return to service after each cleaning.
Minimum maintenance cost
The robust, virtually impervious internal tank that is chemically bound to the polymer concrete structural core during molding is tolerant to operating abuse its smooth,non-stick surfaces minimize adhesion of contaminants.
Maximum operational safety
