Energy and biomass recovery from wastewater. Final report, December 1989--December 1990

PDF Version Also Available for Download.

Description

The goal of the project was to demonstrate in a large pilot study that domestic sewage could be converted to useful products, mainly substitute natural gas and clean water, using two low-cost biological processes -- a high-rate anaerobic treatment unit followed by a hydroponic plant treatment system. The anaerobic attached film expanded bed (AAFEB) and the Nutrient Film Technique (NFT) are two innovative technologies developed over more than a decade at Cornell University. Documentation of this biological system for 52 months at flows up to 40 s/d (greater than 10,000 gal/d) showed the system to be highly successful. This report ... continued below

Description

The goal of the project was to demonstrate in a large pilot study that domestic sewage could be converted to useful products, mainly substitute natural gas and clean water, using two low-cost biological processes -- a high-rate anaerobic treatment unit followed by a hydroponic plant treatment system. The anaerobic attached film expanded bed (AAFEB) and the Nutrient Film Technique (NFT) are two innovative technologies developed over more than a decade at Cornell University. Documentation of this biological system for 52 months at flows up to 40 s/d (greater than 10,000 gal/d) showed the system to be highly successful. This report covers the last 12 months of this jointly sponsored NYSERDA/GRI study. Efforts were made to document the empirical relationships between system loading rate and effluent quality. Although the sewage temperatures varied from 7{degrees}C to 28{degrees}C and little modification of reactor temperatures were made, low temperatures had minimal effects on the purification capabilities. Effluent quality was excellent (BOD and SS less than 5 mg/1) with plant nutrients removed to less than 1 mg/l for total nitrogen and total phosphorus at low hydraulic loadings (less than 3 cm/d). Sludge generation was less than at conventional primary plants and much less than at conventional secondary facilities. The economics of the hypothesized system appear promising.
