This increased oxygen supply accelerates the activity of the naturally occurring micro-organisms which degrade the sewage to a clear effluent and a non toxic sludge. Septic tanks Provide minimum treatment and must now discharge to a soakaway only. They can take up large areas of ground and may be expensive to build. The biodigester is a great example. This represents the level of activity by micro-organisms naturally present in the effluent.

The energy produced by the generator will then be used to power the community and can be sold to the city in order to alleviate its energy shortage. Sometimes we unnecessarily increase complexity. Anaerobic digestion has a defined process flow that consists of four distinct phases. These are often used where the ground conditions and water table are unsuitable for traditional methods of effluent dispersal.

Biogas produced is either combusted or upgraded and then used to displace fossil fuels. If an effluent is too strong for a receiving aquatic environment then oxygen will be naturally depleted in the same process. Putting a steel rod or bamboo pole through the centre of the roll facilitates the extraction of the required length of tube. In pre-treatment, wastes may be processed, separated, or mixed to ensure that they will decompose in the digester. It has several positive impacts.

Discharges to a

The collected methane gas will be channeled through a filtration system and ultimately connected with a methane powered generator. Septic Tanks and Sewage Treatment Plants Soakaways or sub-irrigation systems for dispersal into the ground. The rolls should be protected, especially the edges, and should be stored and manipulated in a horizontal position.

Discharges to a water course may be direct or in-direct. Join Our Team Bio-Digestor The bio-digester utilizes the biodegradable waste in the landfill community by decomposing it to generate methane, and ultimately converting it into electrical energy. The ceramic pipe is inserted to one half of its length in the interior of the plastic tube and the plastic tube is folded around it. The structure of the bio-digester will have a large tank that will hold the waste and specific bacteria which will help to decompose the waste.

Through a chemical process, methane gas will then be an end-product of the decomposition which will then be collected. Where there is a commercial kitchen Hotels, Pubs etc a grease trap must be fitted to the kitchen drainage only. During digestion, waste products are broken down by bacteria and biogas is produced and collected. It would be better to compost this waste.
