Moving Bed Biofilm Reactors (MBBR)
The Siltbuster range of Moving Bed Biofilm Reactors (MBBR) is designed to provide packaged plug and play aerobic biological treatment, easy to operate and easy to maintain.
Based on established fixed film biological treatment our MBBR uses media with a specific area of up to 800m2/m3, providing a substantial greater treatment capacity – up to twice the 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 – housing duty/standby blowers – delivers the airflow through a common manifold with the connection at ground level. A dissolved oxygen meter is supplied 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 often found with alternative technologies such as SAF. Media is retained within each compartment through screens and since it is fixed film growth on the media, the MBBR is very resilient to shock loading and can recover quicker than alternative aerobic processes, such as Activated Sludge or Membrane Bio-reactors (MBR).
Automatic anti-foam dosing can be provided to counteract the foaming that is common with biological treatment systems during seeding.
Our MBBRs can be provided as part of a packaged solution including Lamella Settlement Units and DAF (Dissolved Air Flotation) units enabling entire treatment plants to be taken offline.
