“…Although it is true that, for Spain, quite a few have been published in this regard over the last few years. See, for example, Molinos-Senante et al [17][18][19], Lorenzo-Toja et al [20], Hernández-Sancho et al [5,21,22], Sala-Garrido et al [23][24][25], Hernández-Sancho and Sala-Garrido [26,27]. On the international level, mention should be made of the research carried out by Mahmoudi et al [28] for Iran, or De Jong et al [8], Kemp [29] for the Dutch WWTPs and Gerrini et al [15] for the Danish water services and WWTPs.…”

Abstract:The growing economic and environmental importance of managing water resources at a global level also entails greater efforts and interest in improving the functioning and efficiency of the increasingly more numerous wastewater treatment plants (WWTPs). In this context, this study analyzes the efficiency of a uniform sample of plants of this type located in the region of Valencia (Spain). The type of efficiency measure used for this (conditional order-m efficiency) allows continuous and discrete contextual variables to be directly involved in the analysis and enables the assessment of their statistical significance and effect (positive or negative). The main findings of the study showed that the quality of the influent water and also the size and age of the plants had a significant influence on their efficiency levels. In particular, as regards the effect of such variables, the findings pointed to the existence of an inverse relationship between the quality of the influent water and the efficiency of the WWTPs. Also, a lower annual volume of treated water and more modern installations showed a positive influence. Additionally, the average efficiency levels observed turned out to be higher than those reported in previous studies.

“…Sustainability measures for wastewater treatment processes were studied by many authors, e.g. Balkema et al (2002) [5], Muga and Mihelcic (2008) [1] and Molinos-Senante et al (2014) [6]. Balkema et al (2002) [5] presented an overview of indicators used for comparison of wastewater treatment systems, while Muga and Mihelcic (2008) [1] provided indicators for holistic assessment of the sustainability of wastewater treatment.…”

“…Molinos-Senante et al (2014) [6] attended assessment of wastewater treatment plants by using economic, environmental and social indicators. In case of Molinos-Senante et al (2014) [6], social sustainability was addressed by using qualitative measures for indicators such as odors, noise, visual impact, public acceptance, and complexity.…”

A Modified Bio-Ecological Process for Rural Wastewater Treatment

Limited water resources and ensuring access to clean water are critical environmental challenges, especially for the developing world. In particular, rural domestic wastewater has become a significant source for the pollution of freshwater bodies. A modified bio-ecological A2O-wetland system for rural wastewater treatment consisting of a biological unit (anaerobic baffled reactor, anoxic tank and oxic unit, A2O) and an ecological unit (horizontal flow constructed wetland) was developed, and key performance indicators were identified. The bio-ecological treatment system showed high removal efficiency for pollutants, successfully achieving 91%, 85%, 78%, and 92% removal efficiencies for chemical oxygen demand (COD), ammonium (NH 4 -N), total nitrogen (TN), and total phosphorus (TP), respectively. The concentrations of pollutants in the effluent from the system were lower than the Class 1 A regulated values of the Chinese National Standard GB18918-2002. The system offered high removal efficiency, simple operation, and low energy consumption. The A2O-wetland is a good alternative for rural wastewater treatment systems.
