A single-stage anaerobic lagoon treating dairy manure was studied for approximately four years (April 1987–April 1991). A portion of the lagoon was covered to gather data on biogas production and quality. Methane concentrations in the biogas exceeded 80% throughout the evaluation period. The following relationship between CH4 concentration and sludge temperature was determined: CH4 = 89·514e−0·00381T where CH4 is the per cent CH4 concentration and T is the temperature (°C). Influent and lagoon liquid concentrations for several parameters were monitored. The installation of a separator to process the waste stream going into the lagoon approximately one and a half years into the study reduced the vs loading rate by 17%. Chemical oxygen demand, total solids, volatile solids and volatile fatty acid reductions exceeded 80% (influent compared to lagoon liquid concentrations).
