The Challenge 

Plastics, glass, packaging and sanitary items pollute our water courses. These items are discharged from sources such as Combined Sewer Overflows (CSOs). Litter accumulates on the highway and adjacent ditches and is then washed into the watercourses during rainfall events. We have to protect our environment to maintain a good quality of life for all — our drinking water must remain affordable and fish remain edible for future generations, too.

The Way

Sedimentation tanks, grit traps, separators, flow bifur-cation systems, baffle plates and screens are commonly used technologies for separating coarse debris, floatables and pollution. According to the A 112 guidelines compiled by the German Society for Water Management, Waste Water and Waste (ATV-DWA) dynamic separation can be used for combined and rainwater system treatment. The Steinhardt HydroTwister^® Vortex Separator combines the advantage of all well-known techniques.

The HydroTwister^® Vortex Separator combines 4 treatment methods into one compact system, utilising vortex energy for non-powered operation and self-cleaning of the screen face.

Four functions in one structure:

• debris and grit trap
• screen
• baffle plate
• dynamic separation
