摘要
Various forms of energy are used during a wastewater treatment process like electrical, manual, fuel, chemical etc. Most of the earlier studies have focused only on electrical energy intensity of large-scale centralized wastewater treatment plants (WWTPs). This paper presents a methodological framework for analysing manual, mechanical, chemical and electrical energy consumption in a small-scaled WWTP. The methodology has been demonstrated on a small-scale WWTP in an institutional area. Total energy intensity of the plant is 1. 046 kWh/m3 of wastewater treated. Electrical energy is only about half of the total energy consumption. Manual energy also has a significant share, which means that the small-scale treatment plants offer significant employment opportunities in newly industrializing countries and replaces fossil fuel-based energy with renewable. There is a lack of sufficient data in the literature for comparison, and few studies have reported values that vary significantly due to the difference in scale, scope of the study and the choice of the treatment technologies. Replication of similar studies and generation of data in this area will offer directions for decision on choice of the scale of wastewater treatment process from the considerations of energy and climate change mitigation strategies. © 2012 The Author(s).
