Standard Range: 100-500 persons in a single tank

The Biodigester Standard Range is a bespoke system for the treatment of sewage / waste water for populations or Population Equivalent (PE) up to 2000 or higher using a suitable primary settlement tank or tanks followed by Biodigester Bonus waste water treatment units in parallel.

The second option is Design & Build on site using the Biodigester EK system which consists of all the components required to install an operational Biodigester into locally constructed tanks. Burnham Environmental Services can either supply the Biodigester EK components or undertake the whole project.

Each project is assessed for loading, which may be from sources such as domestic housing, hotels, inns, restaurants or caravan sites. The specific effluent quality required is the second design factor to be included.

Each Biodigester Standard has a four stage process the first two of which are for the primary settlement of solids. The third stage is a Submerged Aerated Filter (SAF) fed with a supply of air so that naturally occurring micro-organisms degrade the waste water to a high degree in the presence of oxygen. The final stage of the treatment process is settlement of the secondary solids which are generated within the aerated filter process. These solids are automatically returned to the primary settlement chambers for storage. The sludge return system also has the important function of recycling effluent throughout the Biodigester.

The Biodigester Standard is normally installed underground. Each Biodigester Standard has a substantial retained volume that allows the advantage of extended emptying intervals. The process design ensures the suitability of the Biodigester 'Standard' for variable loadings.

Further details can be found in the 100-2000 population Biodigester Brochure.

Have had the Biodigester for eight years and it is working very well.

We are very pleased with it.
