Description

For new SWRO desalination plants, Nano-composite membrane elements have demonstrated a 50-100% increase in permeability compared to the current installed base of RO membranes. The inherent properties of nano-composite membranes require less driving pressure to produce the same amount of water, thus lowering a plant’s energy usage by up to 20%.

• It protects the RO high-pressure pump and lead-end RO membrane elements from debris. 200 GPM rating. 2 No.
  
• Membrane Housing: Codeline/Protec fiberglass housing, 8″ diameter, holds 5 membranes, 1000 psi rated pressure vessel, 4No.
  
• Membranes: Energy Saving, nanocomposite seawater membranes, 20 No. 8″x40″
  
• High-pressure RO Pump: super duplex axial piston pump with 8000 service intervals, oil-free, requires the least amount of maintenance in the industry.
  
• Direct Pressure Exchange Device: Included.
  
• High-Pressure Pump Motor (50Hz/380V): 39 kW, 3 Phase, TEFC. The absorbed power is 20.2kw
  
• Direct pressure exchange motor (50hz/380V): 7 kW, 3 Phase, TEFC. The absorbed power is 3.8kw
  
• High-pressure side piping material: 2205 duplex Stainless Steel
  
• Low-pressure side piping material: Schedule 80 PVC
  
• Water quality monitor: feed water and product water TDS meter
  
• Flow meters: Panel Mount Flow Meters for feed water and product water.
  
• Pressure Gauges: Feed Water Pressure, working pressure, Concentrate
  
• System controls (automatic operation): PLC control to provide start/stop, sequential, and alarm control.

RO System starts permissible conditions:

1. Power On
   
2. Start button pushed
   
3. Low-pressure switch closed
   
4. Permeate water tank level below low level (low and high-level switches are on open position)

Five conditions will cause the RO to shut down the machine:

1. High working pressure
   
2. Low inlet pressure (<20 psi)
   
3. Starter overload trip
   
4. Product water storage tank level high
   
5. Emergency shut-down button pushed.

• Low Feed Pressure Shut Off with indicator light
  
• High-pressure shut-off switch
  
• Product Water and raw water Tank level control
  
• System On switch with light
  
• Power On switch with light
