Pure Aqua manufactures industrial water filters that clarify water by removing sediment, turbidity, iron, unpleasant tastes, odors, suspended particles, or unwanted color commonly found in surface ground water. Pure Aqua manufactures media filters using stainless steel, or epoxy coated steel, or FRP tanks. Our industrial water filters can be used in a variety of applications including municipal, institutional and industrial water filtration applications. With the utilization of the correct pressure tanks, valves and accurate filter media choice Pure Aqua's industrial water filters can suit most industrial water filtration requirements. Our industrial water filter equipment can be designed to operate manually, semi- or fully-automatically and require very limited technical knowledge.
Multi-media water filter system represents a significant improvement over single-media filters. This is primarily due primarily to improved filter bed action based on the innovative use and selection of filter media. Multi-media filtration permits delivery of high quality filtered water at much faster flow rates, as compared to a conventional sand filter.
In a conventional sand filter, lighter and finer sand particles are found at the top of the filter bed, and coarser, heavier sand particles remain at the bottom after backwashing. Filtration takes place in the top few inches of the filter bed.
A multi-media filter is backwashed in the same manner as a sand filter, using reverse or upward flow of water through the filter bed. The various layers of media retain their stratification because each material has a different density.
All Pure Aqua steel and stainless steel industrial water filters include pressure tanks constructed of high quality welded steel designed for 100 psi working pressure and tested for 150 psi. Standard pressure tanks are equipped with inlet and outlet connections, top mounted loading port (either handhole or manhole), and a side filter media removal fitting. Due to the corrosive nature of certain filter media types, all carbon steel tanks are epoxy lined.
