Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its beneficial use to enhance nitrogen removal, which is otherwise typically unsatisfactory due to the lack of organic carbon to support denitrification. The project will provide strong support to the Australian water industry in their endeavour to achieve energy- and carbon-neutral wastewater services.

废水的直接厌氧处理将废水中的大部分有机物转化为甲烷，一种能源。然而，产生的甲烷中高达50%溶解在废水中。其随后在好氧处理中被剥离到大气中不仅导致显著的能量损失，而且还排放强温室气体。该项目旨在开发一种技术，不仅避免甲烷汽提，而且使其能够有益地用于增强脱氮，否则由于缺乏有机碳来支持反硝化作用而通常不令人满意。该项目将为澳大利亚水务行业提供强有力的支持，以努力实现能源和碳中性废水服务。
