Balmoral - CAP - About Balmoral CAP
The Balmoral CAP is a biological aeration type treatment plant designed to produce a moderate quality of final effluent in addition to overcoming several of the common problems associated with small packaged domestic wastewater treatment units.| How does it work...? Crude wastewater enters the main outer chamber (1) where the initial settlement takes place, with the heaviest solids sinking and the floating matter rising. The liquor from the main section is transferred to the central chamber (2) where it is continuously aerated by the fine bubble diffuser (4) which encourages bacteria to provide the second stage of treatment. The mid section of this treated effluent is then removed from the chamber through a calming pipe (5) which allows a further brief settlement before discharge (6). The air compressor (7) runs continuously. It is contained within the neck of the tank and is accessible for maintenance if required. Easy access is available to both chambers for desludging which is an annual operation. Key benefits... • Impact resistant body moulded in one-piece polyethylene • Wide base for stability and ease of handling and storage • Sturdy lifting eyes for easy handling and installation • Achieves Royal Commission standards for effluent quality under normal domestic conditions • Powered by a small, near silent air compressor • Corrosion resistant • The Balmoral CAP is tested and approved by the Irish Agrément Board (Cert. no. 02/0148) | Common problems which can occur are... • “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 CAP overcomes these problems because... • There is no “fixed” media within the CAP to become blocked - it operates on the “activated sludge” principal whereby the bacteria floats in suspension in the reactor vessel and forms an “active soup” of “mixed liquor”. • All functions within the tank are operated by air power generated by a small compressor contained in the neck of the tank, 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 fine bubble diffuser. |
