RO System

The construction of the membrane is a Thin Film Composite (TFC). It is the highest quality membrane available in the industry. The reverse osmosis pressure vessel is a heavy-duty housing made of corrosion resistant fiberglass.

  • Pre-Filtration System: PVC housing, 5-micron cartridge type sediment filter further reduces suspended solids in the feed water stream to RO system. It protects the RO high-pressure pump and lead end RO membrane elements from debris. 20 gpm rating. 1 No.
  • Membrane Housing: fiberglass, 4" housing, holds 1 membranes, 1000 psi rated pressure vessel, 6 No.
  • Membranes: Dow Filmtec or equivalent , 6 No. 4"x40"
  • High pressure RO Pump: Super Duplex Stainless Steel.
  • Energy Recovery Device: Not-included
  • Motor (60Hz/230V): Danfoss 7.5 HP, 3 Phase, TEFC. or
  • High pressure side piping material: 316 Stainless Steel
  • Low pressure side piping material: Schedule 80 PVC
  • Concentrate control valve: 316 Stainless Steel
  • Water quality monitor: 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 start 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

Pre-Treatment Systems

Anti-scalant Dosing System
One metering injection systems will be supplied for controlling different elements in the feed water of the RO plant. The metering pump will allow controlling of different functions such as the stroke length and percentage rate. The Antiscalant Dosing System prevents the membrane from scaling.

Multi-Media Filter
A multimedia filter is designed to make better use if the bed depth in the removal of a greater volume of suspended solids. This is achieved by loading larger media granules of lower density at the top of the bed, with at least one layer of smaller media granules of higher density below it. The larger granules remove the larger suspended particles, leaving the smaller particles to be filtered by the finer media. Three depth multi-media filtration system is used to filter sand and sediment (turbidity) down to approximately 20 Microns. Automatically backwashes when clogged. Saves replacement filter cost. Filter size is 9"x48" , with high performance composite & fiberglass tank. 1 .No.

Membrane Cleaning and Flushing Systems 

Permeate Water Flush
The Permeate Water Flush function purges the salt water out of the system by pumping permeate water into the membrane housing before each shut down. This maintains product water quality and extend the membrane life time.

Miscellaneous 

Feed Water TDS Meter 
The Feed Water TDS Meter provides real time salinity reading for the feed water. Range is between 0-100 PPT (parts per thousand).

Feed Water Delivery Pump 
This is a submersible type pump. It has minimum discharge pressure of 40 psi. Pumping rate is 12 gpm. 220V/60hz/single phase. 316SS material.
