Waste Water Treatment Plants

In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within ...
