This paper provides a brief review on wastewater treatment system and the application of life cycle assessment (LCA) for assessing its environmental performance. An extensive regarding geographical relevance LCA WWTPs, evaluation sustainable by in both developed developing countries are also discussed. The objective is to identify knowledge gap, improvement methodology WWTPs. A total 35 publish...

MOST SEWAGE COLLECTION and treatment systems in the U.S. are 30 to 100 years old [EPA(b)] with a total estimated value exceeding $1 trillion [EPA(a)]. EPA estimates that in the year 2000, more than 1.2 billion gallons of raw sewage poured into waterways due to overflow, blockage, leakage or other system faults [EPA(b)]. The construction projects needed to correct these problems will be many and...

Endocrine-disrupting compounds (EDCs), such as estrogen, are known to be present in the aquatic environment at concentrations that negatively affect fish and other wildlife. Wastewater treatment plants (WWTPs) are major contributors of EDCs into the environment. EDCs are released via effluent discharge and land application of biosolids. Estrogen removal in WWTPs has been studied in the aqueous ...

The aim of wastewater treatment plants (WWTPs) is to clean before it discharged into the environment. Real-time monitoring and control will become more essential as regulations for effluent discharges are likely stricter in future. Model-based soft sensors provide a promising solution estimating important process variables such chemical oxygen demand (COD) help predicting performance WWTPs. Thi...

Treating municipal wastewater is a complex and costly process. With rising energy costs sustainability targets, treatment plants (WWTPs) are looking for alternatives to reduce operating carbon dependence. Anaerobic digestion the most common established technology used in WWTPs treat sludge since it can potentially improve recovery sewage costs, mainly due generation of biogas. Biogas renewable ...

Energy recovery, according to circular economy and sustainable principles, has established itself as an inevitable field of action in wastewater treatment plants (WWTPs). costs are forcing the optimization processes increases development applicable waste-to-energy (WtE) technologies. This study aims analyze existing knowledge on WtE research municipal WWTPs using a systematic literature review ...

The direct release of nitrous oxide (N2O) and methane (CH4) from wastewater treatment plants (WWTP) is important because it contributes to the global greenhouse gases (GHGs) release and strongly effects the WWTP carbon footprint. Biological nitrogen removal technologies could increase the direct emission of N2O (IPCC, 2006), while CH4 losses are of environmental, economic and safety concern. Cu...
