• The highest individual weight is 115 kg
• No crane is required on the building site
• Continuous and worry-free operation

The SBR system works with activated sludge, but when compared to standard extended aeration systems the efficiency is much higher, due to the equalised peak flow.

How your SBR sewage treatment plant is delivered

The ClearFox® SBR small sewage treatment plant is fully biological and ready to connect. It is a compact, modular sewage treatment plant with high quality, clog-free airlift-pumps. The system has an integrated energy-saving mode and monitors overfilling with fully automatic pressure measurement.
No calibration is required, as the system does this automatically. The system has an air manifold with high quality and noise-free actuators. The hose connections are made of high quality stainless steel ensuring reliability, as these do not break.

The complete control unit is integrated into the ventilated manhole pit, which saves laying cables etc. Only an inlet, outlet and a power cable (earth cable 3×1,5mm2) must be connected and no further connection work is required! The inlet and outlet openings are prepared for KG DN100 (high-quality EPDM-gaskets are already integrated in the tank).

The monolith tanks are made of high-quality PE. They are manufactured by rotational moulding, which produces a one piece seamless tank without additional work required (as would a screw-connected tank on the contrary). The vertically positioned rib structure of the tank ensures stability, as well as good and ergonomic blending in the reactor. The tanks are equipped with additional internal stainless steel reinforcements.

In their basic configuration the tanks are equipped with a manhole pit extension for an inlet depth of ~78 cm. The tank covers (load-bearing up to 200 kg) are screw-tightened (childproof version). The plant is CE conform and includes DIN EN 12566-3 test certificates for efficiency, water-tightness and fracture resistance. The plant consists of two interconnected tanks which can be placed into the building pit as one piece.

All technical components of the plant are pre-assembled in the factory and are ready to be connected (plug and play).

QuickOne+ Function

The Clearfox® QuickONE+ is one of our most popular small scale sewage treatment systems and for good reason. It produces the best effluent quality on the market but with the lowest energy consumption of any sewage system available. We can prove this with our CE declaration independent test certificate and the DIN EN12566-3 test. It meets local and national wastewater rules and regulations. The ClearFox® QuickONE+ is a pre-assembled small wastewater treatment plant made of stainless steel reinforced polyethylene. The control module and housing is integrated in the (ventilated) manhole shaft above the biology chamber. For installation, only the inlet, outlet and a power cable needs to be connected.

The biology chamber and sampling point are easily accessed by the manhole. Maintenance is simple, as there are no moving parts and installation errors are avoided as it is plug & play.

How does a Clearfox SBR Wastewater plant function?

SBR refers to sequential batch reactor. This technology is a controlled wastewater treatment process. Batches of wastewater undergo treatment in sequence. This control process allows each batch of wastewater to undergo treatment for any required time frame. This enables the achievement of any level of treatment as a result.

In brief, the typical steps in the SBR process are as follows:
The activated sludge treatment plant with SBR has an upstream coarse separator that serves as storage for the primary and secondary sludge and to buffer the inlet water. Sludge filling and Clearwater extraction are effected by means of airlift pumps. The plants control system recognises four main states in the Normal cycle.

1. Filling phase: the sewage enters the first chamber and any large solids are retained. The filling pump then conveys waste water into the second chamber which is the biological reactor.
2. Purification/Aeration stage: The waste water is circulated in the SBR reactor using air fed by the membrane plates and the bacteria are supplied with oxygen, thus supporting the actual biological treatment by microorganisms. Short aeration and non-aeration stages (for denitrification) alternate and are controlled by the computer software. An activated sludge grows with millions of microorganisms which completely break down the wastewater.
3. Sedimentation/settling stage: A rest phase follows. The activated sludge sinks (sedimentation) to the bottom of the water column. This allows a clarified water zone to form at the top of the reactor chamber.
4. Clearwater extraction stage: A Clearwater pump conveys the purified waste water that remains above the “Clearwater discharge point” to the plant outlet, lowering the water level in the reactor. The settled activated sludge is then transferred back into the first chamber and the process repeats with the next batch of wastewater.

A complete purification cycle takes approximately 7 hours

Energy-saving cycle: The purification cycle programme continues running unabated, but with a shorter aeration phase, which reduces the amount of energy required. Depending on the inlet quantity to the prechamber, the programme then decides fully automatically, whether the energy- saving cycle should continue, or whether it should switch back to normal operating mode.
