Abstract

Wastewater treatment processes employed today are many decades old and often do not follow emerging criteria of sustainable development promoting resource recovery as well as smaller environmental footprint while ensuring nutrient reuse and stakeholder involvement. Based on various performances reported and field observations of various poorly operating STPs in South India, it is proposed that an intermediate concept of anaerobic upwelling sludge bed reactor (USB) is proposed to operate with no OandM interventions like a septic tank but providing potential for methane and nutrient recovery at rates and HRTs as practised today, namely HRT < 24 h, loading rates 1-2 kg BOD/m3/d, 70-80 BOD removal, 1-3 years of attention-free operation and moderate effluent turbidity. Some field scale evidence of such function at various locations is provided, and its proposed operation is discussed. © Springer Nature Singapore Pte Ltd. 2020.
