Chapter 6 Evaluation of Combined Heat and Power Technologies for Wastewater Treatment Facilities 6.2.1 Digester Gas Treatment The JWPCP’s anaerobic digesters are operated at mesophilic temperatures and produce about 7.5 million cubic feet per day of digester gas. Prior to combustion, the digester gas receives minimal treatment, primarily to dry the gas. The first step in the digester gas treatment process is particulate removal by venturi scrubbers. Coalescing filters and cooling coils, located immediately downstream of the venturi scrubbers, dry and chill the digester gas to remove moisture upstream of the combustion turbines. Following treatment the digester gas enters a low pressure (5 to 7 inches WC) blending tank where a small amount of natural gas mixes with the treated digester gas. Natural gas is added as a fuel pressure control measure to ensure that the combustion turbines receive a constant supply of fuel. Digester gas production at the JWPCP is somewhat variable and generally increases throughout the week. Early in the week, about 7 – 10 percent of the total fuel volume is comprised of natural gas. Over the course of a typical week the natural gas supply tapers off as the digester gas production increases. By the end of the week, when digester gas production has stabilized, the natural gas supply is shut off. Likewise, as digester gas production tapers off early in the week, natural gas is again added to the system and the cycle repeats itself. Figure 6-2.
