Abstract

This study is conducted to provide useful fertilizer or soil conditioner of sludge from nightsoil treatment plant. Several possibilities present themselves. The major sink for disposal of waste sludge is the land, and in this case values will be measured primarily in terms of agricultural benefits. According to the result of sludge drying experiment, the drying rate with mixing once a day was more increased by three times than the state without mixing. And in sludge, N was 7-9%, P was 0.85-4.14%, and coliform groups in dried sludge were 75 MPN/gr.
