Water through the inlet branch pipe enters the aeration tank, where the main purification of wastewater with the help of microorganisms contained in the activated sludge from organic pollutants and nutrients takes place. In the aeration basin there is also a block of polymeric loading on its surface microorganisms grow in the form of biofilm. Due to the creation of local anoxic conditions in the biofilm the nitrate concentration in wastewater is reduced.
Aeration systemProvides saturation of sludge through aerators from compressor and lets microorganisms breathe, so that biological treatment can be possible.
Secondary settling tank
After the aeration tank, the sludge enters the secondary settling tank to separate the activated sludge. Gravity sedimentation makes it possible to separate wastewater from activated sludge. After that, biologically treated water is sent through the outlet pipe for further disposal in the ground through filtration holes or trenches.
Activated sludge recirculation airlift
Provides continuous biological treatment. Removal of activated sludge from the secondary settling tank into the aeration tank is provided by air supply through a pipeline.
Ventilation riser
Prevents accumulation of gases inside the unit and removes them outside. The cover can be made of fiberglass or aluminum upon request.
