The 'T' range Biodigester is a 'Total Aeration' sewage / waste water treatment plant manufactured in glassfibre (GRP) for simple underground installation. A small air blower is used to provide a supply of air so that naturally occurring micro-organisms grow and degrade the waste water including solids. The final effluent produced is a clear odourless liquid suitable for discharge into a watercourse or a system of soakaway trenches.


The 'T' range Biodigester has the significant advantage of continuous recirculation without any underground moving parts. No septic sludge is stored and as a result the Biodigester product has a unique 'Odour Free' operation guarantee. A Biodigester treatment plant provides the modern environmentally friendly alternative to malodorous septic tanks and cesspools. The substantial retained volume of 'T' range Biodigesters provides a class leading prolonged emptying interval of typically 3 years. The Biodigester product is entirely suitable for variable loadings.
