ANALYSIS OF METHODS OF TREATMENT OF SEDIMENTS PRODUCED IN PURIFICATION OF NATURAL WATER

The article discusses the methods of processing sludge from water treatment plants. From an economic and environmental point of view, the following main areas of treatment of tap water sludge were analyzed: sludge discharge into surface watercourses and reservoirs, burial in the open sea, sludge dehydration in natural conditions (sludge placement in storage ponds), sludge drying on sludge beds or freezing-thawing , sludge compaction in gravity compactors, mechanical dewatering of compacted sludge in belt filter presses or in centrifuges, discharge of sludge to sewage treatment plants and treatment of a mixture of water sludge together with sewage sludge, sludge incineration. It is noted that the treatment of sewage sludge on sludge sites is advisable to use in regions with warm and dry climatic conditions.
