Balmoral SBR technical information
The SBR is an advanced biological aeration type treatment plant designed to produce a very high quality of final effluent in addition to overcoming several of the common problems associated with packaged domestic sewage treatment units.
Common problems which can occur are:
• Peak surges flow (ie. mornings and evenings) can force effluent through the plant before it has had sufficient treatment time
• “Fixed film” types, which have a “media” matrix, can suffer from media blockage because of excessive bacteria growth. Replacement/maintenance of the media material may be required at regular intervals
• Mechanical/electrical components within the tanks are difficult to maintain and can be a safety risk
• The liquor is not spread evenly over the available bacteria preventing an adequate oxygen supply
The Balmoral SBR overcomes these problems by:
• Operating on a storage and batching system - storing the effluent at peak times in the primary settlement tank and treating it in small batches throughout the rest of the day - thereby ensuring that each batch receives the full treatment time
• There is no “fixed” media within the SBR to become blocked up - it operates on the “activated sludge” principal whereby the bacteria float in suspension in the reactor vessel and form an “active soup” of “mixed liquor”
• There are no moving parts or electrical components
within the tank. All functions within the tank are operated by air power generated by a small compressor which is housed in a remote kiosk, allowing
maintenance to be carried out safely and easily
• The bacteria receives a high quality air supply and is completely mixed and aerated by the high volume bubble diffuser.
Holiday mode
If no sewage enters the primary settlement tank in the time taken to complete a cycle – when the sensor in the primary settlement tank does not detect any flow – the unit alternately switches between two hours aeration followed by a two hour settlement period. This cycle continues until the sensor in the primary settlement tank detects sufficient volume to supply one batch at which time it will revert to the normal fill, aerate and discharge cycles.
Holiday mode is designed to keep the bacteria as healthy as possible under zero flow conditions while ensuring the compressor is not running needlessly and wasting energy.
