How They Work

August BioPro wastewater treatment technology satisfies the highest ecological requirements. We offer a logical and economical solution by with lower installation costs and maintenance expenses. The biologically treated water can be reused because of the high quality of the effluent.

All wastewater treatment processes are being performed in one single radial polypropylene container. First, the wastewater flows into a 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. At this point, using gravity, the wastewater flows into the anaerobic fermentation zone (3), mixes with activated sludge and flows into the denitrification zone (4), where the denitrification process begins. From the denitrification zone wastewater overflows into the aeration zone (5).

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