Mechanical treatment of wastewater

Summary

The selection of equipment for mechanical wastewater treatment is an important stage in the reconstruction or new construction of the treatment facilities that determines their efficiency and reliability in terms of the technology and operation. The examples of the currently widespread technical solutions for designing filtering cloth of the screens for mechanical wastewater treatment are given. The effectiveness of these solutions is compared. On the basis of studying wastewater treatment facilities in Germany, a comparison of the debris retention efficiency depending on the applied filtration grade, i. e., two-dimensional (perforation) and one-dimensional (bar spacing) is presented.
