SBR SMALL SEWAGE SYSTEMS

The AquaPur SBR-system is a fully biological sewage system for domestic wastewater from 4 to 50 p.e. (population equivalent), developed and approved in accordance with the latest guidelines of the European Standard EN 12566, part 3. AquaPur has received the latest approvals from the German Institute for Building Engineering in Berlin and can be installed in concrete or various PE tanks. Plants for over 50 p.e. can likewise be delivered without any problem. Installations are also possible for hotels, restaurants and many other commercial enterprises.

Guaranteed easy!
Installation of the plant is easy and quick. All components are prefabricated and the individual parts just need to be connected up. Removal of the control unit from the tank is easy. With PE tanks it is pre-fitted.

What is SBR-technology?

The AquaPur system is a biological small-scale sewage treatment system in accordance with tried and tested principle of SBR technology (Sequencing Batch Reactor). The treatment is completed in only six hours. SBR-technology means that the inflowing wastewater (influent) is treated in batches. The plants are fitted with an emergency overflow. Aeration is achieved by an aeration pump which creates an even level of compressed air. The aeration pump and control unit technology are safely housed away from the wastewater in a cabinet or on a console. Hoses from the switch cabinet to the small scale sewage treatment system supply the individual elements with air. The control unit is ready to plug in i.e. all you need for the installation is a 230 volt socket. Simply plug in and off it goes! The plant runs automatically. All parameters are pre-set.

4 Phases of clear water

Phase 1: Feeding phase
The wastewater in the pre-treatment is fed into the SBR reactor (activation). It is fed out from the sludge-reservoir at a pre-determined height, with the quantity being limited. An air lift pump is used for this purpose.

Phase 2: Aeration phase
In this phase the wastewater is aerated in the activation basin. The biology is optimally supplied with oxygen and ideally mixed. The disc or pipe diffusers on the ground are used for the aeration.

Phase 3: Sedimentation phase
In this stage neither feeding nor aeration takes place. During the sedimentation phase the activated sludge separates from the clear water. A layer of sludge forms on the floor of the chamber, while a clear water zone forms in the upper area.

Phase 4: Extaction phase
The biologically treated water is fed from the upper area of the basin into receiving waters, pond or drainage. The sludge on the basin floor is transported back to pre-treatment. Air-lift pumps (Mammoth pumps) are used for the extraction, without any pumps being in the water.
