Moving Bed Biofilm Reactors (MBBR)

Siltbuster’s range of Moving Bed Biofilm Reactors (MBBR) are designed to be plug and play solutions to integrate with the existing Siltbuster range of packaged treatment solutions.

Based on established fixed film biological treatment our MBBR uses media with a specific area of up to 1000m2/m3. This leads to the MBBR providing a greater treatment capacity within the same footprint when compared with traditional mobile treatment solutions, such as Submerged Aerated Filters (SAFs).

The aeration system uses multiple diffusers within each compartment to provide an even air distribution for mixing energy whilst also maximising the oxygen transfer efficiency. A blower skid delivers the air flow through a common manifold with the connection at ground level. The air flow rate is controlled by a dissolved oxygen meter for optimisation of biological treatment whilst minimising energy consumption.

The MBBR uses a plastic carrier media with a large specific surface area which provides an optimal attachment surface. The movement of the media allows for the regulation of biomass accumulation, thus avoiding the need for scour cycles. Media is retained within each compartment through screens.

Automatic anti-foam dosing can be provided to counteract the foaming that is common with biological treatment systems during seeding. The system utilises a sensor that detects whether foam is present and stops dosing when foaming has been stopped.
