1 to 20 person sewage treatment unit range
The Bio-Pure sewage treatment unit is designed to serve both domestic and commercial properties that have no access to mains drainage. The Bio Pure sewage treatment unit is designed in accordance with BS 6297: 1983 in order to clean the final effluent to a standard of 20mg/l Biological Oxygen Demand (BOD) and 30mg/l Suspended Solids on a 95 percentile basis.
The Bio Pure is a 2 stage extended aeration sewage treatment unit. There is NO first stage primary settlement tank, as with 3 stage sewage treatment units like Klargester, Titan, etc. as the Bio Pure also digests the solids which would normally need to be tankered away on a regular basis.
The wastewater treatment range caters for between 1 and 20 persons,
The Bio Pure sewage treatment unit offers a very discreet solution to on-site wastewater treatment as the small lid is flush with the ground and unlike its rivals; the compressor is housed in a dry safety chamber under the lid, with no visually intrusive kiosk. This ensures that no child or animal can fall in should the lid be removed!
The Bio Pure sewage treatment unit itself is craftsman built, very robust, superb quality, using thicker fibreglass than its rivals and an all-fibreglass internal construction with NO metal struts to corrode. For this reason it carries a 25yr guarantee on all parts of the tank. Compare this with the competition. Unlike the Biodisc, the Bio Pure has NO internal moving parts.
Unlike 3 stage sewage treatment units which settle the solids out in the primary settlement tank for regular emptying via tanker, the Bio Pure digests the solids as well as the organic material in the liquid part of the effluent, achieving 95%+ Total Solids Digestion. This means that the emptying interval is extended up to 5 years, even for the 15 to 20 person units which typically have to be emptied every 3 months when using 3 stage sewage systems.
The Bio Pure sewage treatment system is the answer if you are looking for a top quality, discreet unit with low running costs. It offers outstanding value for money when compared to many other sewage systems.

How the Bio Pure sewage treatment unit works
Air from the compressor, housed under the lid, is piped to a diffuser in the draft tube. Raw sewage enters the aeration chamber and air surging up from the draft tube aerates the sewage, causing an aerobic bacterial colony to establish and digest the organic matter, including the solids. As more raw sewage enters the chamber, an equal amount of effluent displaces through the open bottom of the aeration chamber into the clarifier. The quiet conditions in the clarifier allow all the suspended solids sink to the base of the clarifier and they are drawn back up the draft tube by the upward flow of air for further digestion in the aeration chamber. The clear effluent rises to the top of the clarifier and passes over a weir into the outlet pipe. The Bio Pure sewage system constantly recycles the wastewater via gravity and achieves nearly total solids digestion. Most sewage treatment units consist of three chambers, the first one being a Primary Settlement Tank where the solids form a septic sludge. They require regular emptying by tanker. Because the Bio Pure is digests the solids as well as the organic matter in the liquid, the unit has a much longer emptying interval than any three stage unit. The interval is 4 to 5 years
The Bio Pure sewage treatment unit is designed in accordance with BS6297:1983. It is designed to produce an effluent of 20:30mg/litre BOD/SS on a 95percentile basis
The sewage treatment unit can be adapted at the build stage to suit any inlet or outlet level
Installation .
The Bio-Pure is simple, quick and cheap to install as it has the option of NO concrete for the installation if desired. It requires only soil/sand/gravel as backfill as it is a robust, quality tank. Most other sewage treatment units require a concrete base and a min. 300mm concrete backfill, which makes the installation much more expensive
The sewage treatment unit itself is installed in two halves and the top is eye-bolted to the bottom before the tank is leveled, backfilled with the soil/ gravel and filled with water. The compressor sits in a chamber under the lid, which is designed to keep it safe and dry.
If you have a high water table, there are two installation options.
1. The Bio-Pure sewage treatment unit can be held down via 4 simple metal ground anchors which take 10 mins. to install. Backfill with soil/sand/gravel.
2. A small amount of concrete can be used to cover the anti-floatation Lugs, then backfill with soil/sand/gravel. Full installation manual available
