polluted water treatment Germany

...These microorganisms use the air pollutants as substrate and nutrient medium and convert them into naturally formed decomposition products such as CO2, water, and biomass. Here, the washing water is continuously regenerated and used in a closedcircuit water treatment system. TYPICAL APPLICATION AREAS These plants are primarily used for watersoluble ingredients of the exhaust air. The usual pollutants that are filtered from the exhaust air with the help of bio scrubbers include aldehydes such as formaldehyde, alcohols, ketones and other hydrocarbon compounds.

...In a polluted lake, the dynamic balance is so disrupted that there is an overproduction of organic material. This results in a greater demand for oxygen, which the lake must supply. A critical situation arises, putting all biological life in the lake at risk. To protect the lake, an increase in oxygen input must be achieved. Diffusion aeration represents an effective treatment for increasing the oxygen concentration in shallow lakes, ponds, rivers, and canals.
