polluted water treatment Germany

...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.
