Invited review: Anaerobic fermentation of dairy food wastewater

Possibilities of anaerobic fermentation of food waste on municipal wastewater treatment plants

In presented work, long-term operation of a laboratory anaerobic reactor processing food waste is discussed. Food waste is potentially well available municipal bio waste with light biodegradability and with year-long production mostly in big cities. About 200 days of laboratory work were focused on characterization of tested food waste quality as well as on feasibility of biogas production from...

Aerobic /anaerobic biodegradation of beet molasses alcoholic fermentation wastewater

A study of the aerobic degradation of beet molasses alcoholic fermentation wastewater diluted to 50% (chemical oxygen demand, COD: 82 g/l) was carried out using the following fungi: Penicillium sp., Penicillium decumbens , Penicillium lignorum and Aspergillus niger . These four microorganisms produce a decolorization of the wastewater from the first day of incubation, achieving the maximum deco...

Anaerobic-aerobic Treatment of Dairy Wastewater with National

A short term solution for the treatment of dairy waste water is discussed. Discharge rate'is 500 m3lday with a high organic load (2,750 Kg CODlday). Low capital investment (US $ 330,000) and operational (US$ 0.55lm3) costs were required which ought to be competitive with current market prices but within the official environmental norms imposed by the national agency SEDESOL. The problem was sol...

Anaerobic fermentation of lysine.

Invited review: Sustainability of the US dairy industry.

The US dairy industry has realized tremendous improvements in efficiencies and milk production since the 1940s. During this time, farm and total cow numbers have decreased and average herd size has increased. This intensification, combined with the shift to a largely urban public, has resulted in increased scrutiny of the dairy industry by social and environmental movements and increased concer...
