Prefabricated Systems for Low-Cost Anaerobic Digestion
This paper outlines the development of a low-cost anaerobic digestion plant which accrues the cost benefits of standardised components within a prefabricated structure. The examination of process and cost sensitivities has resulted in a revised plant design using non-conventional (within the U.K. Water Industry) materials and construction techniques. The development of such plants allow digestion provision for much smaller plants than previously considered, thereby reducing overall sludge tankering requirements.
The plant described shows two particular advantages over its conventional counterpart namely cost: at £6/person compared with £4O/person and rapid construction: with erection and commissioning within 18 working days.
