FILTRATION
Waterco Commercial Vessels can be configured to provide general filtration, multi-stage water
treatment filtration, chemical and odor removal, or demineralisation.
Designed for down-flow use, unfiltered water enters the vessel through the upper influent port.
Once entering the distribution header, the water flows through a hydraulically balanced system of
diverters strategically placed over the filter bed.
Even distribution of the water is achieved throughout the filter tank, which results in low levels of
turbulence and minimal differential pressure losses. Water flow paths are parallel and vertical at
the surface of the filter media bed resulting in flow capabilities up to 49m3/m2/hr or 20 US gpm/ft2
velocity without creating channeling within the media bed (depending on media type).
Water is passed through media in a downward direction where it is collected through the use of
“V” slotted laterals or nozzles designed to retain the small filter media particles. After entering the
collection header, the filtered water exits the tank through the lower effluent port.
