example 1
[0148] In 2013-2014, the partial dredging of Lake Schafels in Berlin-Leinigendorf covered the lakeside area to a depth of 3.5 m. The lake has a maximum depth of 6-7 meters. The total area of the lake is 4.14 hectares. The area to be dredged occupies a portion of approximately 1.55 hectares. Therefore, if figure 1 As can be seen in , a large part of the 2.6-hectare lake (corresponding to about 63% of the total area) was not covered by the dredging process during the restoration works. Regarding this undredged area, it involves a stratosphere with a volume of about 50,000m3 and slightly less than 170,000m 3 1 / 3 of the total volume. Before the recovery, a water study carried out in July 2013 by Büro Wassmann from Borgsdorf showed a marked lack of oxygen in the deep waters (hemosphere). Relevant decay processes in the form of hydrogen sulfide products were confirmed by negative redox potentials. Furthermore, the reducing environment promotes the redissolution of nutrients ...

[0163] This example shows how the required CN concentration can be calculated, focusing on different parameters depending on the water flow rate, injection time period, etc., such as the variability of stock solutions, first dilutions, etc. There are various possible values for the starting concentration and the dilution, depending on the sum of different parameters, resulting in the final concentration of the water body (here Lake Schafels). Optimization and therefore measurement is required because the conditions for microbial processes will be different in each water body. It is also necessary to detect the appropriate injection time and measure the temperature, oxygen and redox potential in the depth profile. The appropriate injection time for stratified lakes is stable stratification, which begins with anoxic and, for shallow lakes, negative redox potential / anoxic. In addition, when it is different from the first calculation result, the control of nitrate and oxygen ne...
