6000 litres per day reverse osmosis pure water system
Asset ID RO-002
FOR PURE WATER PRODUCTION IN HARD WATER AREA
This system can produce 6,000 litres per day of low TDS reverse osmosis water suitable for use in a wide range of industrial applications where demineralised or deionised water is specified.
This is a smaller system suitable for a window cleaning business or other industrial user operating in a hard water area
It includes inlet filter housings for where we install two carbon filters in series for dechlorination purposes. Where dechlorination is not required (e.g. non chlorinated borehole feed water) we would install plain 5 micron filters. It includes an antiscalant dosing system to prevent scale forming on the membrane surface.
Reverse osmosis systems are designed to remove dissolved minerals from the water into a concentrate stream that flows in contact with the RO membrane. The concentrate flow cannot be recycled to the appliance and is generally discharged to drain or put to other use (e.g. irrigation)
This appliance requires a good quality feedwater (mains or borehole) at a pressure of 1 bar to be connected to the inlet. A tank for the storage of the pure water is also required as well as a drain connection for the wastewater flow.

PROCESS DESCRIPTION
This system is designed for fully manual operation, although once started it can be left for unattended operation with a recommended visual check once or twice per shift.
It requires feed water with minimum pressure of 1 bar to be provided from mains supply or from borehole pump. This is passed through two cartridge filter housings and dosed with potable water approved antiscalant before it is boosted by the high pressure pump.
Pure water under pressure permeates the reverse osmosis membrane and the dissolved minerals (and antiscalant) are separated out into the concentrate or waste stream. There is no antiscalant in the pure water following treatment.
The pure water exits the membrane and is passed through a flow meter and exits the apparatus. Quality checking of the product water can be carried out manually by the system operator.
The concentrate water exits the system and is usually discharged to drain or soakaway. It is also possible to use this wastewater for irrigation in some circumstances.
The system pressure is manually regulated by hand valve to maintain the overall product recovery (i.e. % conversion of feedwater into purified product) at the specified value.
This system is not equipped for chemical cleaning so is not recommended for use on grey water or untreated surface water (e.g. river, lake, turbid spring)
This system provides an overall removal of dissolved minerals from the feed water of approximately 97%. This water can be used in a variety of industrial applications including window cleaning, aquariums, laboratories, food and drink manufacturing. RO product water is generally not used in potable water networks without some degree of remineralisation in order to maintain pH balance (please contact us for further details).
