Abstract

Wastewater containing organic substances is usually treated by the activated sludge process. With the expansion of sewage systems, the amount of activated sludge increases vastly. In Japan, it becomes increasingly difficult to secure landfill sites for disposing the increase amount of excess sludge. Carbonizing activated sludge has been developed as one of the methods to reduce and/or recycle wastes. Carbonized activated sludge is useful because it contains phosphorus to be extracted from it, and to be a good adsorbent. The amount of the acid-soluble phosphorus in carbonized activated sludge was experimentally estimated in this study.
