|A well-developed sewerage system contributes to the ecological and sanitary safety of the surrounding area. Waste disposal of human activities has long been a serious problem.
One of the main procedures that allow maintenance of the condition of all sewerage elements in proper condition is the cleaning of the sewage system. Depending on the type of pollution, it is realized in several ways. According to the generally accepted classification, there are three: mechanical, thermochemical and hydrodynamic. Manually, with the help of mechanical tools (peaks and cutters), it is easiest to remove outside dimensional objects that fall inside the pipe. In some cases, the implementation of such a method can be problematic. Especially if the pipes lie at a great depth.
The thermochemical method shows the greatest efficiency when removing stale fossilized blockages by the total action of water heated to high temperatures and aggressive chemical compounds. This method is used most often when other ways to soften and eliminate sewage sludge failed.
Sewage cleaning with a high head of water, passing through a special nozzle, is usually called a hydrodynamic method. It is realized by a channel washing machines. Due to its efficiency and simplicity, it enjoys the greatest popularity and is in high demand when removing blockages at various sites.
Sewage cleaning above the indicated methods should be carried out taking into account the features of the object and the type of contamination. The final choice always rests with the performers; therefore, it is necessary to attract specialists with sufficient level of professionalism to the works on sewerage maintenance. Attempts to self-clean the sewer are fraught with unpredictable and sometimes financially costly consequences. Remove the blockage itself is possible only in extremely rare cases, and even then at an early stage of its occurrence. This is evidenced by many years of practice.
