Water purification through reverse osmosis
Medium to large applications
We offer medium sized reverse osmosis units to handle water volumes of between 300 and 500 litres per hour.
Three hundred litres per hour RO units
We show here, the specifications for two of these units. Please enquire for other models and volume capacities.

Most water requires some type of treatment before use, even water from deep wells or springs. The extent of treatment depends on the source of the water. Appropriate technology options in water treatment include both community-scale and household-scale point-of-use (POU) designs.
The most reliable way to kill microbial pathogenic agents is to heat water to a rolling boil but this requires abundant sources of fuel and is very onerous on the households, especially where it is difficult to store boiled water in sterile conditions. Other techniques, such filtration, chemical disinfection, and exposure to ultraviolet radiation (including solar, UV, RO) have been demonstrated in an array of randomized control trials to significantly reduce levels of water-borne disease among users in low-income countries, but these suffer from the same problems as boiling methods.
Over the past decade, an increasing number of field-based studies have been undertaken to determine the success of POU measures in reducing waterborne disease. The ability of POU options to reduce disease is a function of both their ability to remove microbial pathogens if properly applied and such social factors as ease of use and cultural appropriateness. Technologies may generate more (or less) health benefit than their lab-based microbial removal performance would suggest. Reverse osmosis is one very practical solution as it filters at the elemental level, so excluding all pathogens.
