1 to 55 person DM sewage treatment plant range
The DM sewage treatment plant is designed to serve both domestic and commercial properties that have no access to mains drainage. The DM sewage treatment plant 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 DM is a 2 stage extended aeration sewage treatment plant. There is NO first stage primary settlement tank, as with 3 stage sewage treatment plants like Klargester, Titan, etc. as the DM also digests the solids which would normally need to be tankered away on a regular basis.
The DM wastewater treatment range caters for between 1 and 55 persons.
The DM sewage treatment plant offers a very discreet solution to on-site wastewater treatment as the small lid is flush with the ground.
The DM sewage treatment plant itself is craftsman built, very robust, superb quality, with a thick GRP base and a polyethylene top section. Unlike fibreglass, this does not crack. It has an all-fibreglass internal construction with NO metal struts to corrode. For this reason it carries a LIFETIME process guarantee. Compare this with the competition. Unlike the Biodisc, the DM has NO internal moving parts.
Unlike 3 stage sewage treatment plants which settle the solids out in the primary settlement tank for regular emptying via tanker, the DM 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 DM 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 DM sewage treatment plant works
Air from the compressor, housed next to the unit,, 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 DM sewage plant 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 DM 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 DM sewage treatment plant 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 plant can be adapted at the build stage to suit any The DM also has the ENXXXXXXXXXX new certification for wastewater treatment units and has undergone extensive testing in Germany for 10 months. The effluent is tested every day under strenuous conditions and the DM passed every test. Some extended aeration units have NEVER been tested by anyone and are merely copies of the extremely successful DM tank, but without any certification. BEWARE of copycat units which claim to be 'designed to' a certification standard rather than actually having the standard itself as they have either never been tested by anyone or have failed to attain the certification!
Installation
The DM is simple, quick and cheap to install as it has the option of NO concrete for the installation if desired. They are usually installed in under 3 hours. 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 and a 2 day job.
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 kiosk beside it, buried in the ground, which is designed to keep it safe and dry.
High Water Table Installation
1. The DM sewage treatment unit can be held down via 4 simple metal ground anchors which take 10 mins. to install. Backfill with soil/sand/gravel.
