One of the main problems in Russia is an acute shortage of free land for the disposal of solid domestic waste and sewage sludge. The treatment and removal of precipitation is a major problem in wastewater treatment. Urban sewage treatment plants were built on model projects in the 1970s, in which natural dehydration on silt areas was provided. Sludge dehydration on silt areas of sewage treatment plants of medium and high capacity is impossible due to the lack of free land areas. The major drawback of this method is the rejection of significant land areas, contamination of the geo-environment, the release of pollutants into the air, as well as the loss of land resources. In sludge processing and utilization, it is necessary to achieve minimum damage to the environment and to increase the possibility of using it on behalf of the national economy. The adoption of new technology and processing of sediments allowed to reduce the initial amount of precipitation by 4 times and to reduce the humidity from 97% to 83%, the amount of sludge formed at the treatment facilities will decrease by 6 times (from 300 m3/day to 50 m3/day) as a result of dehydration of the filter presses, the will be a reduction in the surface concentrations of pollutants in the atmosphere from 5,4 tons per year to 2,9 tons per year.
