A Continuous Aeration Plant (CAP), is desigfned to provide full tratment to crude sewage in a normal domestic enviroment. The CAP teats sewage to a higher standard than a septic tank, but does no offer the same degree of control available from a Sequential Batch Reactor (SBR) The standard of effluent discharged from a CAP is such that it does not need to be passed through a soakaway and can be discharged directly to a watercourse.

The balmoral Sequential Batch Reactor (SBR) has proven, beyond doubt, to provide the highest standards of efflient quality in the market-place. The Balmoral CAP, while not designed toi rivel the SBR in terms of effluent quality, offers an efficient, economic and enviromenally freindly alternative to either septic tanks or premium sewage treatment plant.

Technical information

The Balmoral CAP is a biological aeration type treatment plant designed to produce a moderate quality of final effuent in addition to overcoming several of the common problems associated with small packaged domestic sewage treatment units.

Common problems which can occur are:

• "Fixed film" types, which have a "media" matrix can suffer from media blockage because of excessive bacteria growth. Replacment/maintenance of the media material may be required at regular intervals.
• Mechanical/eletrical components within the tanks are difficult to maintain and can be a safety risk
• The liqur is not spread evenly over the avaible bacteria preventing an adequate oxygen supply.

The balmoral CAP overcomes these problems becauses:

• There is on "fixed" media within the CAP to become blocked up - it operates in the "activated sludge" principal whereby the bacteria floats in suspention in tjhe reactor cessal and forms an "active soup" of "mixed liquor"
• There are no moving parts or eletrical components within all the tanks. All the functions within the tanks are operated by air power generated by a small compressor housed in a remote chamber, allowing maintenance to be carried out safely and easily.
• The bacteria reeives a high quality air supply and is completely mixed and aered by the high volume fine bubble diffuser.
