The RO unit Includes the appropriate high-pressure pump, FRP pressure vessels, spiral wound thin film composite RO membranes, Sch 80 PVC low pressure feed piping, and high-pressure piping or hose. 

This RO system is skid mounted assembled, hydro-tested and functionally tested before leaving our factory.

The RO system supplied includes PLC based controls and is capable of automatic operation with minimal operator intervention. Safety devices are provided to protect the RO system and its components from common fault conditions.

Level controls, located in the owner’s permeate storage tank, will send a control
signal to the RO system control panel to begin the start sequence.

At the start signal the feed valve will open and membrane flush valves will open. At the end of the pre-flush cycle the membrane flush valve will close.

As water pressure builds in the RO high pressure feed pump suction line, a pressure switch senses the line pressure of the water entering the pump. This switch activates a timer which delays further start sequences until all water lines and pressure vessels reach normal start-up pressures. At the end of the time delay, a start control signal is sent to the RO high pressure feed pump starter.

The RO high pressure feed pump then starts and supplies the necessary feed water
pressure to the membrane array.

The RO feed water is split into two streams, permeate or purified water and concentrate or reject water. The RO permeate flows to the permeate water storage tank. The concentrate is disposed of in accordance with local environmental regulations or method of reuse. When the permeate storage tank is full the level switch sends the shutdown signal to the RO control panel and the system then begins it’s post-flush cycle which removes all concentrated contaminants from the system. Once complete, the system waits for the next start signal.
