20 m3/day reverse osmosis system

Asset ID RO-001

FOR PURE WATER PRODUCTION

This system can produce 20,000 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.

It is installed in a stainless steel frame on heavy duty sanitary casters so that it can be moved easily to its point of use.

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.

Reverse osmosis systems are designed to remove dissolved minerals from the water into a concentrate stream that flows in contact with the RO membrane. Therefore we recommend that the feed water is soft or dosed with a suitable antiscalant to prevent the membrane becoming clogged with hard water scale.

SPECIFICATIONS

PROCESS DESCRIPTION

Pressurised feed water is provided from mains supply or from borehole pump. This is passed through two cartridge filter housings before it is boosted by the high pressure pump.

Pure water under pressure permeates the reverse osmosis membrane and the dissolved minerals are separated out into the concentrate  or waste stream.

The pure water exits the membrane and is passed through a flow meter and quality checker on route to its point of use or storage facility.

The concentrate water also exits the system via flow meter and is usually discharged to drain. It is also possible to use this wastewater for irrigation in some circumstances.

The system pressure is 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 and the membrane production will naturally decline over time if the membrane becomes scaled. For this reason we recommend that the feed water is softened or dosed with a suitable antiscalant (contact us for further details).

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 food and drink manufacturing. RO product water is generally not used in potable water systems without some degree of remineralisation to avoid corrosive conditions (please contact us for further details).

The system includes two auxiliary relays that can be used for level switches in associated tanks.
