Domestic wastewater treatment

Since fiscal 1987, Panasonic has been working on sewage treatment in rural communities. Sewerage systems in agricultural village areas are generally not as advanced as in urban areas, so we have been pursuing a small-scale dispersal type sewage treatment facility. By fiscal 2007, we had delivered 85 units, mainly in Hyogo Prefecture.
   The greatest challenge in sewage treatment is the large amount of sludge generated during the sewage treatment process. To resolve this problem, we developed a sludge reduction plant called EcoSludge. By breaking down the sludge using ultrasonic waves, the plant can reduce the amount of sludge by 75%.
