Notes on the E-Cell MK-3MiniHT Stack:
1. Actual site conditions may affect the performance of the system. It is recommended to use Winflows projection software to confirm the expected water quality, resistivity, sodium, and silica performance guarantees under the specified design conditions. For boron or any other guarantees, please contact Veolia for further details.
2. The inlet pressure is determined by several factors, including the downstream pressure requirements for both the product and concentrate streams, the choice of counter-current or co-current operation mode, and the pressure drop across the stack.
3. Nominal flow rates and a temperature of 25°C are the reference conditions. It is advisable to refer to the Winflows projection software for verification under the actual design conditions.
4. Please refer to the Winflows projection software and the E-Cell Stack Owner’s Manual to ensure that the feed water specifications are suitable for the design conditions of the system.
5. TEA (Total Exchangeable Anion) represents the total concentration of anions in the feed water, including contributions from OH-, CO2, and SiO2. It is essential to use Winflows to confirm that the feed water TEA is acceptable under the specific operating conditions of the application. The table value provided is based on minimum flow and maximum temperature.
6. The feed water hardness limit of 1.0 ppm as CaCO3 applies specifically to standard counter-current flow operation. However, when operating in co-current flow mode, the allowable feed water hardness decreases to 0.1 ppm as CaCO3.
7. The allowable silica limit decreases when the flow exceeds the nominal value. Additionally, the limit further decreases to 0.5 ppm if the feedwater hardness is above 0.5 ppm as CaCO3.
8. The boron feed level is capped at 0.3 ppm as B whenever there is a requirement for a silica guarantee or a resistivity guarantee exceeding 10 MOhm-cm. Higher boron levels could potentially affect the system's performance. Without these requirements, the limit is extended to 1.0 ppm boron.
9. Reverse Osmosis (RO) or an equivalent process is recommended for providing feed water to the EDI system. RO effectively removes particulate matter, colloidal material, and high molecular weight organic substances that can foul the ion exchange media. Since EDI stacks contain packed beds of ion exchange medium that cannot be backwashed/fluidized, it is crucial to specify the RO permeate quality. Systems with an open loop between the RO system (or other source) and the E-Cell (e.g., a tank, decarbonator) must incorporate filters immediately preceding the E-Cell to protect it from contamination by particulate matter. Generally, a 5 µm absolute or 1 µm nominal filter is considered acceptable.
10. APHA color standards/scales are named after the American Public Health Association and are defined by ASTM D1209. These standards help measure and classify the color of water, which can be an indicator of water quality.
