Small scale tapioca industry in Bogor uses simple technology and equipment with a production capacity around 5 tons per day. The tapioca industry uses large amount of water to process the raw materials and to produce a large amount of liquid waste. The tapioca production consists of various processes, such as washing, extraction and settling process which produce a lot of liquid waste. This liquid waste contributes to the environmental pollution because it contains a lot of organic materials. The wastewater of tapioca industry generally has a high BOD, COD and TSS materials. The objective of this research is to calculate the potential waste water recycling in small scale tapioca industries in Bogor. Recycling this waste water can be done in two ways such as onsite recovery (reuse of waste water in the same process) and reuse (waste water uses for other process). Small scale tapioca industry in Bogor has an average production of 2.5 tons per day and produces liquid waste of 5070 litres/ton cassava. The identified potential usage of recycling waste water is recycling waste water for other process such as washing, milling, settling process and the conversion of waste into valuable product such as methane as a fuel. With this waste water recycling process, the tapioca industry will have a benefit in form of cost saving, and environmental benefit.
