These land based, non sea water Reverse Osmosis (RO) systems can be categorised as two types; mains towns water system typically running on low pressure and brackish water type, where typical uses would be ground water or in desert areas, where feed water quality is largely inconsistent due to differing aquifer levels brought about by heavy or no rainfall.
We have supplied, installed and commissioned pre-treatment filtration, RO with triple sequence pumping arrangement and chemical dosing equipment to various oil and gas companies in The Algerian oilfield. These bespoke systems have proved over the years to deliver good quality drinking/site water and have proved they can operate very successfully in desert conditions. The sites utilise a ring main type distribution system.
Brackish water RO systems tend to be larger and more robust than the tap water models due to the extra pressures required to desalinate the water with higher levels of total dissolved solids (TDS).
These economical low pressure tap water, 'plug and play' off the shelf ROs are aimed at the small to medium market where an improvement on mains drinking water quality is a given however, these can be used in the production of demineralised water (DI water) used for battery top up or window cleaning spot free rinsing, by increasing the life of the DI resin substantially.
