Cleaning of drains

Wastewater treatment is a set of sanitary and technical measures aimed at removing or neutralizing harmful substances contained in wastewater. These substances may be of chemical or microbial origin. Chemical pollution can be caused by the use of various chemicals in industry, agriculture and other industries. Microbial contamination can arise from the use of wastewater to irrigate crops or the discharge of waste into waterways.

Wastewater treatment is necessary to protect the environment and human health. It helps prevent pollution of reservoirs, rivers and lakes, and also reduces the risk of the spread of infectious diseases. Wastewater treatment can be carried out using various methods such as mechanical, chemical and biological treatment.

Mechanical cleaning involves removing large particles such as sand, stones and other hard materials. Chemical treatment involves the use of various reagents to remove harmful substances from wastewater. Biological treatment is carried out using microorganisms that decompose organic substances and neutralize harmful microorganisms.

An important stage of wastewater treatment is its removal of harmful substances. This can be achieved by using various methods such as filtration, coagulation, sedimentation and others. Also an important step is the removal of odor and color from wastewater, which can be done by using special reagents.

In conclusion, wastewater treatment is a necessary measure to ensure a safe environment and prevent the spread of infectious diseases. Various treatment methods remove harmful substances from wastewater and ensure its safety for humans and the environment.

Wastewater treatment is a set of sanitary and technical measures aimed at eliminating microbiological and chemical pollution of wastewater, as well as replenishing consumed oxygen for the normal functioning of microorganisms. Wastewater is obtained after human life processes and the functioning of industrial enterprises and agricultural organizations. Due to the fact that pollutants entering water bodies contribute to the emergence of acute and chronic diseases, standards are established for domestic and industrial wastewater that determine the safe degree of pollution for water bodies of a particular type.

If in urban or rural centralized sewerage systems there is a clear lack of nutrients to maintain the ecosystems of reservoirs, then wastewater standards are tightened. The main way to eliminate pollution is the construction of treatment facilities. After the construction of treatment plants, a number of processes occur that require additional energy and resources. .Environmental problems can be solved using a closed cycle, in which treated wastewater is returned to enterprises that support the livelihoods of the population. The basis is a closed cycle of water circulation, which allows you to preserve natural resources and eliminate environmental pollution. When dirty water is discharged , the creation of barriers is required. Desalinated water is discharged into the river in order to protect other water management facilities, in particular utility networks and reservoirs. There is a global approach to the problem of wastewater discharge into rivers, called efficient water use. The purpose of using this technology is to reduction of pollution. The main environmental requirement is that the amount of recycled water be equal to the volume of contaminated waste. Clean water is used several times in this process, preventing the entry of contaminants and bacteria. An important role is played by high-quality water intakes, which do not affect the reduction of the concentration of pollutants substances entering local treatment facilities.
