Balmoral - SBR - About Balmoral SBR
The Balmoral Sequential Batch Reactor (SBR) combines the efficiency of activated sludge aeration with batch treatment to provide exceptional effluent quality even under extreme loadings.In common with all Balmoral products, no compromise is made with regard to quality or design and the advanced technology and materials used in the manufacture of the SBR will ensure a lifetime of reliable service with the very minimum of maintenance.
| How does it work...? Crude wastewater enters the Primary Settlement Tank (PST) (2) where gross solids settle out and the supernatant liquor remaining near the surface can be drawn off. Substantial “buffer” storage volume is provided in the PST to cope with even the most extreme peak flow loadings (3). A set volume (or batch) of the liquor is transferred to the Reactor Vessel (RV) by an “air-lift” pump (4) where it is mixed and aerated by a powerful air bubble diffuser (5) for a period of 4 hours. During this aeration cycle efficient oxygen transfer cultures a dense “soup” of bacteria (the active sludge) which feeds on the sewage liquor thereby removing most of the organic pollutants. After aeration, the bubble diffuser is switched off and there is a settling period during which the dense activated sludge sinks to the bottom of the RV leaving behind the clarified effluent, (7) which is then discharged into the drain by a second “air-lift” pump (9). All functions within the tanks are operated by air power which is supplied by an electric air compressor and the system is controlled by an integrated programmable unit which monitors the process to take account of flow conditions. | The Balmoral SBR has been designed and built by Balmoral Tanks in association with the University of Abertay, Dundee, Waste Water Technology Centre, who acted as external consultants. The university carried out an in-depth test programme during which the SBR was tested and evaluated alongside a leading competitors model. The aim of the development programme was to design a unit which was not only very robust and reliable but which would provide outstanding effluent quality without the need for expensive “add on” equipment and would also overcome technical problems - (such as peak surges through the bio-zone), which most current designs have failed to adequately address. The final report from the WWTC confirms that the Balmoral SBR out-performs its rivals in almost every respect and that it has the capability to meet even the most onerous effluent requirement. Key benefits... • Controlled batching of water treatment provides unrivalled effluent quality • Bespoke designs available to meet specific flow and load requirements • Completely separate control kiosk houses a modern PLC control system • No high voltage electrics within the tanks providing a safe design • Internal venting pipework • Tested and approved by the BBA?(Cert. no. 01/3786) and Irish Agrément Board (Cert. no. 02/0150) |
