Methods for Kinetic Analysis of Methane Fermentation in High Solids Biomass Digesters

Richards, Brian K.; Cummings, Robert J.; White, Thomas E.; Jewell, William J. (Pergamon Press plc, 1991-04)

Methods are presented for kinetic analysis of anaerobic biomass reactors. In some cases, assumptions implicit in kinetic analysis techniques developed for conventional dilute digestion modes are not applicable to systems ...

Starvation and Overfeeding Stress on Microbial Activities in High-Solids High-Yield Methanogenic Digesters

Hedrick, David B.; Vass, Arpad; Richards, Brian K.; Jewell, William J.; Guckert, James B.; White, David C. (1991-05)

ethane production from a high-solids digester was significantly decreased by both feedstock starvation and overfeeding. Both starvation and overfeeding also induced significant decreases in acetate turnover, acetate ...

High Rate Low Solids Methane Fermentation of Sorghum, Corn, and Cellulose

Richards, Brian K.; Cummings, Robert J.; Jewell, William J. (1991-12)

Sorghum, sorghum/alpha-cellulose mixture, and corn were anaerobically digested at 55°C at effluent solids contents of 8-12% total solids (TS), using trace nutrient supplementation. Volatile solids (VS) loading rates at ...

Odor Control from Livestock Waste Handling Systems

Koelsch, Rick (1993-02-24)

Odors originating from livestock wastes are often the source of irritation between agricultural producers and rural and suburban neighbors. Because individual tolerance for farm-related odors varies substantially and odor ...

In Situ Methane Enrichment in Methanogenic Energy Crop Digesters

Richards, Brian K.; Herndon, Frederick G.; Jewell, William J.; Cummings, Robert J.; White, Thomas E. (1994-01)

A simple in situ technique to enrich digester offgas, which normally contains 30-50% carbon dioxide (CO,) by volume, was developed to take advantage of the differing solubilities of CO, and methane (CH,). Dissolved CO, was ...

On-Farm Biogas Systems Information Dissemination Project

Campbell, Joseph; Koelsch, Richard; Guest, Richard; Fabian, Eileen (1997-03)

This dissemination project studies how three New York State farmers manage anaerobic digesters on dairy farms.

Anaerobic Digestion and Wetland Treatment Case Study: Comparing Two Manure Odor Control Systems for Dairy Farms

Wright, Peter (1998-07)

A comparison of two existing odor control treatments on dairy farms in NY shows the costs and benefits of each system. On one dairy farm an anaerobic digester is used to stabilize the manure and collect methane for the ...
