Product Description
EDI STACK
EDI is an innovative approach to electrode ionization that replaces conventional mixed bed water treatment technology to delivery dramatic benefits for your operation. Its modular stack-and-rack design makes.
An industry leader in ultrapure and high purity water technology with up to 18 MOhm-cm resistivity
SUEZ’s E-Cell* electrodeionization (EDI) technology removes residual salts and ionizable aqueous species – such as carbon dioxide, silica, ammonia and boron – from your water sources. The EDI systems operate chemical-free, achieve 97% water recovery, and consume only electricity. They are ideal for multiple applications including: power generation for boiler feed and NOx control, semiconductors, microelectronics, food and beverage, and pharmaceuticals.
E-Cell technology dates back to 1978 and SUEZ has been innovating ever since to develop a reputation of high reliability and performance, while consuming less energy than the competition.
E-Cell EDI Benefits Versus Ion Exchange:
EDI requires no regeneration chemicals which simplifies environmental, health and safety concerns and reduces chemical costs
EDI operates continuously which minimizes risk of breakthrough from exhausted resin and simplifies operations by eliminating the need to take a system offline for regeneration
EDI reduces facility requirements by having a smaller footprint and lower height requirement than ion exchange, particularly when including supporting equipment such as chemical dosing systems
EDI has no hazardous wastewater discharge and wastes can be easily recycled without the neutralization systems needed for ion exchange

Notes:
1. Actual performance may vary based on site conditions. Refer to Winflows Prediction Software to verify expected product water quality and the resistivity, sodium and silica performance guarantees provided at design conditions. Contact us for boron or other guarantees.
2. Inlet pressure is determined by downstream pressure requirements for product and concentrate streams, choice of countercurrent or cocurrent operation, and stack pressure drop.
3. At nominal flow and 25°C. Refer to Winflows Prediction Software to verify design conditions.
4. Refer to Winflows Prediction Software and the E-Cell Stack Operating Manual to verify feedwater specifications at design conditions.
5. TEA (ppm as CaCO3) - Total Exchangeable Anions, this represents the concentration of all anions in the feedwater, including contributions from OH-, CO2 and SiO2. Winflows must be used to confirm that the feedwater TEA is acceptable at the given application operating conditions. Tabulated values are given at minimum flow and maximum temperature.
6. The 1.0 ppm feedwater hardness limit as CaCO3 is for standard countercurrent operation only. Under co-current operation, the allowable feed water hardness is reduced to 0.1 ppm as CaCO3.
7. At rates above nominal flow, the allowable silica limit is reduced. When feed water hardness exceeds 0.5 ppm as CaCO3, the allowable silica limit is reduced to 0.5 ppm.
8. When a silica guarantee requirement exists or a resistivity guarantee requirement is above 10 MOhm-cm, the boron feed level is limited to 0.3 ppm as B, as higher boron levels may affect performance. In the absence of these requirements, the limit is 1.0 ppm boron.
9. Reverse Osmosis (RO) or Equivalent Feed Water: RO provides feed water to the EDI that is essentially free of particulate matter, colloidal materials, and high molecular weight organic matter that could foul the ion exchange media. Because the EDI stack contains packed beds of ion exchange media that cannot be backwashed/fluidized to remove particulate matter, the quality of the RO permeate needs to be specified. Systems with an open system between the RO system (or other source) and the E-Cell (e.g., storage tank, decarbonator) must have a filter installed immediately before the E-Cell to protect the E-Cell from contamination by particulate matter. Generally, a 5µm absolute filter or 1µm nominal filter is acceptable.
APHA - Color standard/scale named after the American Public Health Association and defined by ASTM.
