Tehran south WWTP is the biggest WWTP in Iran.In the course of extensive enhancement of module 5 & 6, two biofilter systems from Tholander each with a capacity of 30.000 m3/h to eliminate practically the entire odour emissions, was installed and are in operation. The enhancement of the plant includes cleaning of the waste air from the new sludge drying facility and the liquid way.
Benefit from the advantages of the biofilter and of the counter current scrubber in one single system. Thanks to the high specific surface of the packing material and the controllable irrigation a demanding concentration of contaminants like H2S can be treated in a compact system.
Similar to the biofilter, the biotrickling filter is a biological odour control with the difference that the sorption of contaminants takes place in a trickling bed instead of a filter bed. This packing is in its construction similar to the one in a packing scrubber. The difference is that it is loaded with a much lower irrigation density.
