Ultrafiltration is an advanced pre-treatment method. First of all is the system excellent in cases of open intake for seawater reverse osmosis plants, since the conventional sand filtration may prove less effective in these conditions. Ultrafiltration modules are also used to treat river water, due to feed water prone to fluctuation in turbidity over seasons.
We use this technology successfully in our projects. Most noteworthy, we have produced drinking water from river water and other surface water bodies. Here the main challenge is impurities that lead to microbial formation.
Several containerised Advanced Watertek ultrafiltration units operate in remote villages in Africa, where they are the only safe and reliable source of fresh water for entire communities.
