Product Description

Fast installation/reasonable maintenance:  These unique filter orifices in the pyradeck media create an ideal condition for colloidal flock to accumulate. 

The flock forms a blanket which acts as a polishing filter.

All of this is made possible by controlling the velocity of the water.

B.O.D. and suspended solids of less than ppm WILL BE MET with reasonable maintenance.

Typical Specification:

One reinforced precast concrete fixed media filtration tank shall be supplied to remove suspended solids and B.0.D. from the effluent from a secondary sewage treatment plant. This filtration process is an upflow design through a uniform grid. As the liquid flows upward through the uniform grid (Pyradeck), a velocity change takes place that causes the solids to settle on top of the grid. When the solids are dropped out of suspension, a solid blanket forms on top of the media to further enhance the filtration process. As the suspended solid removal rate increases, a B.O.D. reduction takes place that further purifies the effluent. The unit can be cleaned by lowering the liquid level below the media and having the solids fall through the media to the bottom of the tank. Lowering the water level is accomplished by turning on the backwash pump. Complete cleaning of the tank is done by running the backwash pump until the tank is emptied. The filtration tank shall consist of two cells operating in parallel each having capacity for 500 gal/day/Sq.Ft. if using Flow Equalization or 250 gal.day/Sq.Ft. without Flo.
