Pretreatment Module: Media Filtration


Water pretreatment is the process of removing impurities and contaminants from raw water. And Media Filtration helps to ensure that the water quality is consistent, regardless of external factors such as weather or pollution. These processes remove particles and ions from the water to produce purified water. Water pretreatment has several benefits, including extending the lifespan of reverse osmosis membranes, ensuring a dependable water supply, and reducing costs.

Rotek manufactures a large range of media filtration systems for a wide variety of applications including whole-house filtration, reverse osmosis
pre-treatment and post-treatment, and commercial industrial uses. Our filtration systems are equipped with automatic or manual control valves for hassle-free regeneration and backwash cycles.
