“August ir Ko” UAB wastewater treatment technology satisfies the highest ecological requirements. We can offer logical and economical solution by installing the wastewater treatment complex with lower installation and exploitation expenses. The biologically treated water can be reused because of the high cleaning parameters.

All wastewater treatment process is being performed in one single radial polypropylene content. At first, wastewater flows into non-aerated zone, where mechanical pretreatment takes place (2). The non-aerated zone is divided by several internal dividing walls, where internal circulation is established. Further, using gravity, the wastewater flows into anaerobic fermentation zone (3), mixes with activated sludge and flows into denitrification zone (4), where proceeds denitrification processes. From the denitrification zone wastewater overflows into aeration zone (5) .


The compressed air through single-bubble aeration elements – diffusers (6)- is incorporated into aeration zone and into airlifts for circulation and re-circulation of the activation mixture. The air supply is from the only mechanism in the system – air blower (9). In the aeration zone proceed wastewater oxidation and nitrification processes. Further, the mixture of activated sludge flows into bottom of sedimentation section (7), where activated sludge by airlift is recycled into denitrification (non-aeration) or nitrification (aeration) zone of plant.
