The cost of single-use systems and the space they occupy are two important considerations for plants that must treat combined sewer overflow or sanitary sewer overflow (CSO/SSO) in wet weather. The dual-use WWETCO FlexFilter™ addresses both. In dry weather, it provides extra capacity for existing primary or tertiary systems. In wet weather, it efficiently and effectively helps prevent untreated waters from spilling directly into nearby waterways. The FlexFilter’s unique gravity-fed design has no internal moving parts and no media loss. It easily handles high-solids loading and supports automated operation, making it an ideal choice for plants that need an unattended satellite system.
