High-quality PP. The plus in safety
Whether chamber surfaces, covers or frames – renovations to the wastewater infrastructure are an ongoing issue. The material is the problem. In the past, mainly concrete chambers were used. They are susceptible to biogenic sulphuric acid corrosion. Hydrogen sulphide, which forms from wastewater, escapes into the sewer atmosphere and diffuses into the concrete. On walls that do not come into contact with water, sulphuric acid develops, which in turn reacts with the concrete. Scientists at Graz University of Technology* have shown that this results in corrosion rates that can completely destroy the concrete components within just a few years. In contrast, high-quality polypropylene, used to make AWASCHACHT PP, among other things, resists biogenic sulphuric acid corrosion, so that it can even be used to drain aggressive industrial wastewater.

Made entirely of PP, AWASCHACHT has virtually no surface that biogenic sulphuric acid can corrode. The new hybrid support ring has now closed the last gap.
The new hybrid bearing ring stands out with its firmly interlocked inner surface made of polypropylene. This results in further advantages in addition to consistent corrosion resistance:
Available for AWASCHACHT PP DN 1000/800 and DN 600.
