WP440L-Series Reverse Osmosis System
Installation Instructions and User Manual
Page | - 6 -
Design Assumptions
• Systems rated at: 77°F (25°C) using 1000 PPM sodium chloride solution operating at 200 psi pressure.
• Minimum feed pressure to RO System: 40 PSI. System capacity changes significantly with water temperature. For
higher TDS a water analysis must be supplied and could result in modifications to the system.
• Chlorine must be removed if present in feed water prior to RO with a carbon filter or with chemical injection.
• Water must be pretreated with a softener or antiscalant injection to avoid scaling the membranes.
• Feed water turbidity: Less than 1 NTU; Feed water silt density index (SDI): 3 maximum. If exceeded, pretreatment with
media filter recommended. All pretreatment equipment and SDI test kits are available from Applied Membranes.
• Capacity Basis: 24 hrs/day.
Design Notes
1.
Pump flow/Feed flow:
The pump has been designed to include recycle flow (if any) coming back to the pump inlet
from the concentrate stream based on desired recovery. The sum of permeate flow, concentrate flow and recycle flow
(if any) will equal the pump design flow.
2.
Permeate flow:
Indicates design flow rate from RO membranes as product water for use.
3.
Concentrate flow:
Water flowing to the drain. Concentrate flow is critical for proper system operation. For proper
concentrate flows, refer to the system design information on pages 3-4.
4.
Recycle flow:
Flow stream that returns from the concentrate line back to the pump intake, rather than to the drain.
Note 1: Permeate flow should not exceed recommended flow.
Note 2: System pressure is a variable. It is important to adjust the pressure to get the correct
permeate and concentrate flows. The exact value of the pressure is not important.
Note 3: Permeate flow will increase at higher temperature.
