Situation
Noggerath® rotary drum screen
Hechingen, Germany
A drum screen - about 20 years old and in need of repair - at the Hechingen waste water treatment plant had to be replaced. The new machine should conform to the state of the art and take over fine screening behind the coarse screen as before.

The innovative new product development of Passavant-Geiger GmbH, the Noggerath® rotary drum screen RSI, is subject to a longterm performance test with purchase option.
Städtische Werke Hechingen agreed upon checking the Noggerath® rotary drum screen RSI for a period of several weeks in the first instance and subsequently to decide on whether to buy the drum screen.
Solution
In the course of half a year the drum screen RSI mastered various rain and thunderstorm events and periods of drought to the complete satisfaction of the customer who consequently purchased the machine.
Advantages
- Screen drum can be swiveled
- No screenings prone to clogging in the discharge area
- Higher DS content
