|Description:||The new structure for shared coarse screening is followed by the biological treatment in the old and the new part of the treatment plant. The biological treatment of the old part is located in the reconstructed biological filters. In one of these filters, the former stony material was substituted with the special plastic material SESSIL, the first time this filter medium for sewage water treatment was used in the Czech Republic. A two-stage biofiltration and nitrification make it possible to treat one third of the volume of sewage water. The remaining two thirds are treated in a new biological line equipped with all stages of treatment at up-to-date level , and featuring computer-controlled operation.|
