SBR Reactors
The way of working of our biological treatment plants (SBR) is based on low loaded active sediment without oxygen stabilization of sediment together with biological nitrification and denitrification. Those treatment plants consist of single container, where the same processes as in typical treatment plants ( flowing type) take place, but without initial and secondary settler.
In the SBR system we can distinguish two basic stages of the process, namely phase of supply and gathering sewage in reactor and sedimentation phase. The worked out system of time control assures the right course of successive phases of the cycle i.e. aeration together with circulation of biomass in the reactor and blending when aeration is on. During the blending the amount of inserted oxygen to the reactor is controlled and adjusted to the demand through the oxygen probe. After specific time for the gathering sewage phase or after reaching the maximal filling of the container, which is recorded by the probe, the SBR reactor moves on to sedimentation phase. In this stage distinct border between sediment and treated sewage is being formed. When the time designed for the sedimentation phase has passed the phase of piping off the treated sewage to the receiver begins.
- treatment of municipal sewage coming from:
- individual households,
- small service structure, as hotels, pensions, schools, kinder gardens, social help house,
- housing estates,
- small and medium industrial plants…
- treatment of industrial sewage usually as a next stage of treatment after pre-treatment, for example mechanical or chemical.
