Jul 31, 2008Sewage gas generated from the sludge treatment facility in the Higashinada Sewage Treatment Plant (Higashinada ward, Kobe, Hyogo Prefecture) was mainly used as a boiler fuel, but 30 percent of the gas was burnt off as waste. The city of Kobe has succeeded in purifying this waste sewage gas for use as a fuel for natural gas vehicles.

One crucial element of our stone wastewater treatment systems is our innovative Hy-Pack filter presses, which provide an effective means of dewatering sludge. Waste goes into the equipment as liquid sludge and then can be removed as dry, compacted filter cake that meets all landfill requirements, making disposal far easier than it would otherwise be.

all the sludge produced by the proposed wastewater treatment plant at McMurdo could be dewatered in a 10- by 16-m by 2-m-deep freezing bed. Sludge would be frozen by pumping it into the bed in 8- to 10-cm layers during the months of March through September. The total depth of frozen sludge by the end of this period is estimated to be 1.5 m.
