Pretreatment Filtration

Pretreatment filtration is vital to most water purification systems and removes contaminants that can affect final water quality or downstream treatment processes. Pretreatment equipment includes multi-media turbidity filters that remove particulates and other suspended solids to approximately 25 microns; carbon filters that remove chlorine, chloramines and organics; water softeners that remove hardness ions; filters that remove iron; and bag or cartridge filters that remove more nominal or absolute micron sized particulates. These filtration components can be used separately to address specific site treatment requirements or designed into water purification systems to eliminate premature fouling of reverse osmosis membranes and to minimize interference with the ion exchange process.
