Anaerobic filter treatment of wine distillery waste
… COD of 24 000 mg/l) are stabilized by the anaerobic contact process. This process requires fairly close operational control, and a degree of technical competence which is often tacking in many small plants. McCarty has recently developed the submerged anaerobic fitter as an effective means …

Feasibility study of upflow anaerobic filter for pretreatment of municipal wastewater
Feasibility Study of Upflow Anaerobic Filter for Pretreatment of Municipal Wastewater SUMMARY Anaerobic reactors have been successfully installed in full-scale plants world-wide for treating high-strength industrial wastewater over the years. Recently, there has been significant interest in …

Treatment of a glucose-starch waste by the anaerobic filter process
… in Bel lvi lie could be treated by means of. an anaerobic filter. At present the waste 1s being treated anaerobically in two clarigesters. An experimental anaerobic filter was bui It and 0 operated for 129 days at an average temperat~re Qf.34 C and for a further 52 days at a reduced average …

Modeling of Biological Activity in Expanded-Bed, Anaerobic Activated Carbon Filters
… were developed and verified for expanded-bed, anaerobic activated carbon filters. The concepts of liquid-layer mass transport, biofilm molecular diffusion, and Monod kinetics were incorporated in developing the models. Acetate was the single-stage substrate studied while phenol was examined in …

Anaerobic Digestion of Separated Cattle Slurry
… at a 5 day RT (35oC) from SCS in an upflow anaerobic filter than a conventional digester. This was attributed to the retained biomass preventing overloading in the upflow anaerobic filter.<br/><br/>

Treatment of food processing industrial wastewater using two stages anaerobic system
… and suspended solid. In wastewater treatment, anaerobic process is favorable due to its low cost, biogas production, low sludge production and more. In this study, upflow anaerobic sludge bed (UASB) and hybrid-UASB (HUASB) reactors, were combined with anaerobic filter (AF) bioreactors forming …

Monitoring the Stability of Anaerobic Digestion Using a Novel On-line Bicarbonate Alkalinity Monitor
… pH buffering capacity, or alkalinity. In anaerobic digesters the bicarbonate levels should be within 10 to 50mM to ensure stable operation. Bicarbonate concentration in wastewater treatment processes is routinely measured off-line by titration with standard acid to a set pH value. However …

Anaerobic/aerobic pretreatment of blue crab (Callinectes sapidus) cooker wastewater
… creates local DO depletion in receiving waters. Anaerobic treatment of this wastewater was studied for the reduction of COD. Nitrification was studied for the conversion of ammonia, present at levels above 1,000 mg/L NH3/NHA4-N, to nitrate for possible denitrification. COD reductions averaging …

Hydrogen production via dark fermentation of carbohydrate-rich substrates
… stage could be fed to a second anaerobic digestion stage to recover more energy as methane and to stabilise the effluent. Although anaerobic digestion is well established, fermentative hydrogen production is not.<br/><br/>This work evaluated the feasibility of hydrogen production …

Dairy Manure Flushwater Treatment by Packed-Bed Anaerobic Digesters
… performance of three pilot-scale packed-bed anaerobic digesters with walnut shell medium was researched for treating dairy freestall barn flushwater. Reciprocation mixing was evaluated as a means to lessen channelization in the media bed and to improve biogas production and organic matter …
