WL-BFG bead filter is closed pressure filter, not only designed with nice and modern apperance, but also minimize the size of filtration system compare to the traditional one. The installation and operation is very simple, and function is very complete. It provides mechnical filtration and biological filtration at a single unit, with bobbin-wound fiberglass reinforced tank, 6-way multiport valve, piping, circulation pump, air blower, control box and base.
When the water flows through the filter tank, large particles will be trapped by the filter media, small particles will be also blocked by the linked filter media. After certain time, these particles will be accumulated and the pressure inside the tank will increase, then the filter can be backwashed to clear the accumulated particles and release the tank pressure.
By breeding beneficial bacteria inside the filtration media in the filter tank, the beneficial bacteria can convert into non-toxic substance and digested.
