Screening is designed to trap more or less bulky materials and all kinds of waste contained in the inlet channel of a hydraulic structure or at the pretreatment stage of domestic wastewater, agricultural wastewater or industrial wastewater, to allow their extraction, storage in a bin and evacuation to a treatment pathway. One or more float level switches regulate the water level upstream or downstream of a screening system, which makes it possible to determine the fouling level of the screen. |
