Disinfected water for your safety

High levels of viruses and germs in water bodies.

The biologically treated wastewater from small WWTP is often discharged into surrounding bodies of water or used directly to irrigate the garden. However, the hygienic quality of the biologically treated wastewater from a small wastewater treatment plant is not suitable for safe reuse. The wastewater still contains pathogens such as bacteria of the species "Escherichia coli" (E. coli) and the group of "intestinal enterococci". 

In order for you to enjoy your bathing pleasure in natural waters or to be able to reuse your treated domestic wastewater, the wastewater must be disinfected. This irreversibly inactivates pathogens.

Biological wastewater treatment by the SBR cleaning processes Batchpur or AERO serve as a preliminary stage and specifically prepare the domestic wastewater for treatment in the UV-module.

In the upstream clarification process, bacteria gradually break down biodegradable substances from the domestic wastewater (such as carbohydrates, fats, proteins). Easily degradable carbon compounds can be completely degraded to CO2 and water or incorporated into the cells of the bacteria. As a result, biomass is built up. The biologically treated clear wastewater is then extracted from the clear water zone and passed directly through the UV module. The UV module contains a UV-C radiation source that emits light with a effective wavelength at 254 nm. The biologically treated wastewater flows through the UV module whereby genetic information of the bacterial cells is damaged by the UV-C radiation. Enzymatic mechanisms to repair the cells no longer achieve sufficient effect, stopping cell proliferation. A sufficient UV dose ensures reliable killing of all bacteria in the wastewater. The largely standardized plant technology ensures that the customer benefits from high quality as well as optional water reuse.
