Sewage lifting unit with solids separation system

 

Application

The DrainLift FTS solids separation system is a sewage lifting unit for the drainage of commercial buildings and blocks of buildings (e.g. hotels, department stores, etc.).

Raw sewage that cannot be piped to the sewer system through the use of natural inclines and sewage from below the backflow level are to be piped to the public sewer system by means of an automatic lifting unit in accordance with DIN EN 12056/DIN 1986-100. Sewage containing mineral oils or explosive admixtures must be guided through oil precipitators and/or petrol precipitators; those containing fatty substances must go through grease traps and those with sand through grit chambers.
