3. OPERATING PARAMETERS
Parameter | Value / Range |
Recovery | Up to 96%; subject to design conditions |
Operating feed-water temperature | 4.4–40°C (40–104°F) |
Operating inlet pressure | ≤6.9 bar (100 psi); required pressure depends on downstream pressure requirements, flow configuration and stack pressure drop |
Pressure drop | 1.4–2.8 bar (20–40 psi) at nominal flow and 25°C |
Voltage | 0–300 VDC |
Amperage | 0–5.2 ADC |
Feed-water pH | 4–11 |
Feed-water source and particulate requirement | RO permeate or equivalent feed-water quality. If an open system is located between pretreatment and the stack, install a filter immediately before the stack |
Total exchangeable anions (TEA, as CaCO₃) | ≤63.6 ppm; table value is at minimum flow and maximum operating temperature. Confirm acceptability under the specific operating conditions |
Conductivity equivalent | ≤109 μS/cm |
Total hardness (as CaCO₃) | ≤1.0 ppm for standard counter-current operation; ≤0.1 ppm for co-current operation |
Feed-water silica (as SiO₂) | ≤1.0 ppm; the allowable limit decreases above nominal flow and is ≤0.5 ppm when feed-water hardness exceeds 0.5 ppm as CaCO₃ |
Total organic carbon (TOC, as C) | ≤0.5 ppm |
Total chlorine | ≤0.05 ppm |
Fe, Mn and H₂S | ≤0.01 ppm |
Boron | ≤1.0 ppm; ≤0.3 ppm as B when a silica guarantee or a resistivity guarantee above 10 MOhm-cm is required |
Oil and grease | None detectable |
Oxidizing agents | None detectable |
Color | ≤5 APHA |
Maximum hot-water sanitization temperature | 85°C (185°F); sanitization condition, not normal operating temperature |
Maximum hot-water sanitization inlet pressure | 2.1 bar (30 psi) |
Hot-water sanitization cycles | 160 cycles |
Feed-water limits and expected product-water quality should be verified for the specific design conditions using Veolia’s Winflows projection software and the E-Cell Stack Owner’s Manual.
4. Key Features & Benefits
Hot-water sanitization: The stack can be sanitized at up to 85°C (185°F) for 160 cycles, supporting systems that require a hot-water-sanitizable EDI stack.
Defined flow range: A nominal flow of 3.4 m³/h (15 gpm) and a flow range of 1.6–5.4 m³/h (7.0–23.8 gpm) provide sizing references for system design.
Counter-current operation: This configuration supports a feed-water hardness limit of ≤1.0 ppm as CaCO₃, compared with ≤0.1 ppm for co-current operation.
Product-water quality projections: A resistivity guarantee of ≥10 MOhm-cm may be available. Expected quality and guarantee availability must be verified for the design conditions in Winflows.
