OVERFLOW WITH A SCREEN IN PARTICULAR FOR A RAIN RESTRAINT BASIN

摘要

The basin (1) is equipped with an overflow chamber (3) comprising two overflow devices (4) and an emergency overflow. The overflowing water is guided into a circular space (17) between a cylindrical outer part (10) and a perforated cylindrical filter (13) creating a chamber for collecting the dirt particles. A rinsing fluid is guided by a nozzle (23) accommodated in a spherical shell into the chamber and connected with its rear end to a pressure generator. The filter (13) is vertically rotated by an electric drive (31).
