The Ultra Filtration system, also referred to as the UF, is another variant of membrane based technology, used by Advanced Watertek. UF systems are capable of removing a high percentage of microbes from the feed water. The UF process has modest energy requirements and offers a simple, chemical free, user-friendly method of treating water.
UF is considered an advanced pretreatment method in case of open intake for sea water reverse osmosis plants where the conventional sand filtration may prove less effective. UF modules are also used to treat river water where feed water is prone to fluctuation in turbidity over seasons. We have successfully used this technology in our projects to produce drinking water from river water and other surface water bodies where the main challenge is not salt content, but other impurities which lead to microbial formation.
Several containerised Advanced Watertek UF units are under operation in remote villages in Africa where they remain the only safe and reliable source of fresh water for the entire community.
