Glendon® BioFilters


Glendon® BioFilter Technologies and their affiliates currently market, design, construct, install, and service two models of residential wastewater treatment units. Both units are upflow media filters and are based upon the same patented principles, which involve the biological treatment of septic tank effluent as it flows upward through sequential layers of mineral filter media within an in-ground containment vessel and then out of the vessel through matric and gravitational forces. No separate drainfield is required as final treatment and effluent disposal occurs in the native soil surrounding the vessel. The effluent from the vessel is conveyed from the vessel to the prepared native soil through the cover sand material. This cover sand is the top layer of sand, which continues over the rim and out over the native soil at the perimeter of the containment vessel.

The two Glendon® BioFilter models share the same wastewater treatment components, incorporating pre-treatment (septic tank), dosed distribution (pump chamber, controls & mechanics), biological treatment (BioFilter), and treated wastewater disposal (perimeter absorption area). Many of these components exist with other treatment systems. Glendon® BioFilters are uniquely characterized by the shape, size, volume and setting of its containment vessel or basin, the treatment media inside, the dispersal / disposal medium surrounding the unit, and the hydraulic dosing pattern to the filter.
