C. Patel et D. Madamwar, BIOMETHANATION OF A MIXTURE OF SALTY CHEESE WHEY AND POULTRY WASTE ORCATTLE DUNG - A STUDY OF EFFECT OF TEMPERATURE AND RETENTION TIME, Applied biochemistry and biotechnology, 60(2), 1996, pp. 159-166
This paper describes the results of a study aimed at improving the eff
iciency of anaerobic digestion of salty cheese whey in combination wit
h poultry waste or cattle dung. Best results were obtained when salty
cheese whey was mixed with poultry waste in the ratio of 7:3, or cattl
e dung in the ratio of 1:1, both on dry weight basis giving maximum ga
s production of 1.2 L/L of digester/d with enriched methane content of
64% and 1.3 L/L of digester/d having methane content of 63% respectiv
ely. Various conditions such as temperature and retention time have be
en optimized for maximum process performance.
