Stacked High-quality Ultrapure Water Reverse Osmosis EDI Module For Water Treatment

Stacked High-quality Ultrapure Water Reverse Osmosis EDI Module For Water Treatment

MK-7 is designed to

• Provide ultrapure water for industrial applications including power and general industry.

• Produce mixed bed quality water on a continuous basis.

• Require no caustic or acid for regeneration of ion exchange resin within the stack.

• Be leak free, guaranteed.

• Eliminate brine injection and concentrate recirculation, simplifying system design.

description and use

MK-7 are high flow electrodeionization (EDI) stacks which use electrical current to deionize and polish reverse osmosis (RO) permeate water. MK-7 product water is at an ultrapure level required in today’s most demanding applications.

Notes:

1. Actual performance may vary depending on site conditions. Reference Winflows projection software to verify expected product water quality as well as the resistivity, sodium, and silica performance guarantees that are offered for the design conditions. To obtain boron or other guarantees, contact Veolia.

2. Inlet pressure is determined by the downstream pressure requirements for the product and concentrate streams, the choice of counter-current or co-current operation, and stack pressure drop.

3. At nominal flow and 25°C. Reference Winflows projection software to verify for design conditions.

4. Reference the Winflows projection software and the E-Cell Stack Owner’s Manual to verify feed water specifications for the design conditions.

5. TEA (ppm as CaCO3) - Total Exchangeable Anion, this represents the concentration of all of the anions present in the feed water including contributions from OH- , CO2 and SiO2. Winflows must be used to confirm the feed water TEA is acceptable at the specific applications’ operating conditions. Table value is at minimum flow and maximum temperature.

6. 1.0 ppm as CaCO3 feed water hardness limit applies to standard counter-current flow operation only. Allowable feed water hardness decreases to 0.1 ppm as CaCO3 in co-current flow operation.

7. Allowable silica limit decreases above 5 m3 /h flow. Allowable silica limit decreases to 0.5 ppm with feedwater hardness above 0.5 ppm as CaCO3.

8. The boron feed level is limited to 0.3 ppm as B whenever there is a silica guarantee requirement or resistivity guarantee requirement above 10 MOhm-cm, as higher boron levels could impact performance. Without these requirements the limit is 1.0 ppm boron.

9. Reverse Osmosis (RO) or equivalent feed water: RO provides EDI feed water that is substantially free of particulate matter, colloidal material and high molecular weight organic substances, which can foul ion exchange media. RO permeate quality is specified since EDI stacks contain packed beds of ion exchange medium that cannot be backwashed/fluidized to remove particulate matter. Systems with an open system between a RO system (or other source) and E-Cell (ex. tank, decarbonator) must be fitted with filters immediately preceding the E-Cell, to protect the E-Cell against contamination with particulate matter. Generally, a 5 µm absolute or 1 µm nominal filter will be acceptable.
