UTILIZATION OF SEWAGE SLUDGE ON LAND - RATES OF APPLICATION AND LONG TERM EFFECTS OF METALS
Disposal of sewage sludge is an expensive and sensitive problem. Utilisation on agricultural land is a favoured outlet for sludge but it is important that the sludge is applied in accordance with crop requirements for nutrients and that contamination problems are avoided. The opening session of the Seminar deals with principles for rates of application of sewage sludge including the use of sludge in various agricultural situations and also in forestry and for the reclamation of derelict land. The second session is concerned with effects of metals and includes papers mainly from the Scandinavian countries which report results of long-term field experiments and other aspects of the metal problem. The most effective way to avoid contamination problems in sewage sludge disposal is to remove metals from industrial effluents before their discharge to the sewer. This is discussed in two Swedish papers in a final session on administrative measures to reduce cadmium in society, cadmium being a contaminant of major concern in sewage sludge.
