Abstract
Investigation of dewaterability and applicability of UASB sludge to ag ricultural lands were the objectives of this study. Under laboratory c onditions, 90% of sludge moisture percolated in 4 days. Desorption of metals such as copper and lead did not occur under normal conditions. Desorption of metals occurred only at pH I or less. UASB sludges have strong affinity for metals. The nutrient value of these sludges are sm all compared to commercial fertilizers. (C) 1998 IAWQ. Published by El sevier Science Ltd.
