To carry out these works, a temporary wastewater holding system and a temporary screening plant are required. This consists of suitable pumps that convey the incoming wastewater from the grit trap and route it into a mobile container with screens. From there, the pretreated wastewater is supplied via the existing channel outside the screening building to the sand trap. The new screening plant consists of 2 screening lines, each with one bar screen bypass and one screenings washing press. One screening line can pass through up to 500 l/s under normal operation. In the case of inspection/maintenance, one screening line should be able to clean an incoming wastewater flow of 1000 l/s. The two bar screen bypasses each have a screenings washing press assigned to them. The pressed…
