Efficient wastewater treatment is one of the most important engineering tasks for enterprises, municipal infrastructure and various production facilities. The stability of the treatment facilities, the resource of subsequent equipment and the quality of treatment of incoming wastewater depend on the correct choice of the technological scheme. The modern cleaning complex is not a separate machine, but a sequence of interrelated processes, each of which performs a specific function.
Pre-mechanical cleaning is a particularly important step. It is here that large debris, fibrous inclusions, sand and other contaminants that can damage pumps, pipelines and process equipment must be removed from the stream. Such engineering solutions are developed and manufactured by the company TECHMETMASH, specializing in equipment for water treatment and wastewater treatment at https://texmetmash.ru /.
Why do we need mechanical wastewater treatment?
Wastewater entering wastewater treatment plants can contain a variety of contaminants. In municipal systems, these are household waste, textile and fibrous materials, sand and other solid inclusions. In industrial enterprises, the composition of pollutants depends on the characteristics of the technological process.
The ingress of large particles directly into pumping or more complex cleaning equipment can lead to clogging, accelerated wear and emergency stops. Therefore, mechanical cleaning usually becomes the first barrier that takes on the largest contamination.
Grilles of various designs are used to detain them. Depending on the operating conditions, the equipment may differ in the method of cleaning, the size of the gaps, the performance and the principle of movement of trapped waste. Automation of this stage makes it possible to reduce the volume of manual operations and ensure more stable operation of structures.
Grates and crushers as part of sewage treatment plants
Mechanical gratings are designed to filter the flow and separate solid inclusions. In practice, rake, chain, screw, drum, step and other structures are used. The choice of a specific solution depends on the flow rate of the liquid, the nature of the contamination, the size of the channel and the requirements of the flow chart.
In some systems, it is advisable not only to retain waste, but also to grind it. Grate crushers and specialized crushing equipment are used for this purpose. Such installations help to reduce the size of solid inclusions and organize further passage or processing of crushed material in accordance with the provided technology.
