The Bio Euro Clean System
How it works
The Bio Uro Clean Wastewater Treatment System utilises a Sequential Batch Reactor (SBR) process to treat domestic wastewater from dwellings to a very high standard.
Treatment
Treatment is carried out in two phases, in the primary chamber and secondary treatment chamber, as follows:
Primary chamber
Domestic wastewater enters the primary chamber, which has adequate capacity to accommodate and
balance out peak flows (eg morning or evening).Here, heavy solids settle out on the base of the
compartment, where they remain until desludging. Lighter debris and grease rise to the surface to form a crust. At regular intervals, a predetermined volume of the settled liquid is transferred by airlift pump, to the treatment chamber.
Secondary treatment chamber
The liquid from the primary chamber is aerated, enabling the cultivation of colonies of aerobic bacteria (biomass), which break down the organic matter. Following a settling period, the clarified effluent is pumped for discharge to the percolation area. The treatment cycle then recommences, providing there is sufficient volume of wastewater in the primary chamber to constitute a batch.
When there is insufficient inflow of wastewater to the primary chamber within the cycle time, the unit
switches to an alternative cycle or ‘holiday mode’. This cycle continues until adequate volume of wastewater is detected in the primary chamber and normal operation resumes.
