Gelsenkirchen, Germany -- Specialist hose manufacturer Norres Schlautechnik has developed a new polyurethane tube diffuser for sewage-treatment plants, a recent company statement said.
Pro2Air, which will be added to the company's Environmental Solutions Business portfolio, is constructed from "premium" polyurethane and is free from any softeners to avoid hardening or embrittlement of the tube-diffuser membrane, Norres said.
Compared to traditionally used raw materials, "premium polyurethane provides increased flexibility and mechanical strength under dynamic loads," the statement said, adding that the PU diffuser also displays high tensile strength, tear resistance and longer service life.
A slit perforation also guarantees a uniform bubble pattern and optimal oxygenation efficiency across the complete specific air flow range, the German hose specialist added. (RD)
