Project Portfolio:

Project: Tedco Agri Makmur, Bandur Lampung

The project included the design, installation and commissioning of a closed lagoon anaerobic bioreactor on the settling lagoon of a cassava mill; the Tedco Agri Makmur in Bandur Lampung, Sumatra. The objective of the project was to treat the high levels of COD found in the mill effluent and to ensure that the methane gas produced could not escape to the atmosphere and contribute to the greenhouse effect. The project commenced with the design phase and a period of testing to ensure that all parameters of the wastewater and the location were known before investment in the plant began.

Key Project Data

Project Specification

The project was designed to treat the effluent produced from the production of cassava, one of the staple foods of Asia. The mill processes 200 tonnes of cassava a day and the lagoon was built to handle 50,000m3 of wastewater, with 3,600m3 being produced on a daily basis.

 It was designed to process over 1,000Nm3/hour of biogas, the equivalent of 2 MWe and enough energy to power the entire operation leaving an excess to export.

Project Budget

Project budget of USD $4 million.
Project delivered within the specified programme and on budget.
