Advanced Trickling Filter for Wastewater Treatment

reportActive / Technical Report | Accession Number: ADA018318 | Open PDF

Abstract:

A prototype advanced trickling filter unit using a foamed silica medium was designed, constructed, installed, and evaluated. The reduction in biochemical oxygen demand BOD and total suspended solids TSS were the parameters of most interest. The design hydraulic load of the unit was 700,000 gallons per day. The design organic load BOD was 80 pounds per 1000 cubic feet per day. The design solids load was 60 pounds per 1000 cubic feet per day. The assumed organic and solids concentrations were 40 mgl and 40 mgl, respectively. Laboratory data shows that the effluent BOD was reduced from 29 mgl to 18 mgl. The TSS reduction was from 64 mgl to 32 mgl. This indicates a reduction that will allow the upgrading of existing treatment plants to a level consistent with newer effluent limitations. The installation and operation of GaryGlas advanced trickling filters were economical. These filters demonstrated their effectiveness and efficiency as a wastewater treatment system.
