Summary of the subject: The discipline "Treatment and utilization of sewage sludge" is important for the specialty "Construction and civil engineering". Today, for many cities, settlements and industrial enterprises, the problem of treatment and disposal of sediments, which are formed during water purification, is very acute. Often, for tens of years, sediments in their untreated form flowed onto overburdened silt sites, dumps, tailings storage facilities, quarries, which led to a violation of environmental safety and the living conditions of the population.
