The new Roediger brochure on Vacuum Sanitation Technology in hospitals addresses the hygiene topic and shows how we achieve a considerably higher standard of hygiene with our Vacuum Sanitation System which is a proven technology in hospitals for more than 40 years. In the Federal Health Gazette March 2020, the RKI (Robert Koch Institute) published its âRequirements of hygiene for wastewater-carrying systems in medical facilitiesâ and described there that wastewater systems in hospitals are a major factor in the spread of pathogens. Multiresistant germs, but also dangerous viruses are distributed through the sewage systems via aerosols and droplets in the hospital rooms and represent a significant risk of infection.
