This treatment plant draws upon the advantages of normal aeration systems but with the benefits of a sequence batch reactor (SBR) to reduce energy use. It is easy to install, simple and trouble free to operate; and unlike most treatment systems does not need to run constantly. The plant is ideal for domestic and light commercial applications and available in three sizes up to a unit for 10 occupants.
The use of a piston compressor, housed in a waterproof capsule below the access cover, makes operation of the plant virtually undetectable to the ear. The piston compressor is close to where the air is required so less energy is used.
By using batch processing, the compressor only operates when needed to save energy. A level sensor can be fitted to automatically activate a “holiday mode” program. Alarm feature fitted as standard.
The piston compressor was originally developed for life saving medical applications. By housing it in the access shaft it is protected from extreme temperature fluctuation which prolongs the operating life of the compressor.
The shallow dig tank makes the plant easy to install and visually discrete. Concrete is not required for this strong 8mm thick, ribbed polyethylene tank even in poor ground conditions. Plant includes integrated sample chamber.
Accepted by the EA for exception from consent to discharge under the new EPP2 scheme. Cost effective
The unit only needs to oxygenate the water when a batch of effluent is discharged into the reactor chamber. This efficient processing means the operating cost is only £8-10 per person per year.
