Abstract Aquatic ecosystems worldwide are impacted by an influx of nutrients and sludge particles from wastewater treatment plant (WWTP) effluents, leading to a degradation benthic habitats loss associated macroinvertebrate taxa. Hence, in WWTPs, only few tolerant taxa remain. These detritivore play important role the organic matter, biotic interactions between these may either enhance or reduc...

The evaluation of activated sludge control strategies in wastewater treatment plants (WWTP) via mathematical modelling is a complex activity because several objectives; e.g. economic, environmental, technical and legal; must be taken into account at the same time, i.e. the evaluation of the alternatives is a multi-criteria problem. Activated sludge models are not well characterized and some of ...

This thesis presents a general model for the carbon footprints analysis of wastewater treatment plants (WWTPs), using a life cycle assessment (LCA) approach. In previous research, the issue of global warming is often related to traditional industries with high carbon dioxide (C0 2) emissions, such as power plants and transportation. However, the analyses of wastewater treatment plants (WWTPs) h...

Wastewater treatment plants (WWTP) located in regions far from a high-pressure grid can produce renewable biomethane, which partially substitute the natural gas locally consumed. However, economic viability of implementing biomethane WWTP has to be guaranteed. This paper uses discount cash flow method analyze producing Évora (Portugal). The results show that, under current conditions, it is unp...

The wastewater quality index (WWQI) is one of the most significant methods presenting meaningful values that reflect a fundamental characteristic wastewater. Therefore, this study was performed to develop prediction approach using WWQI for regional treatment plant (WWTP) in Melaka, Malaysia. system WWTP provides huge amount registered data due many parameters recorded daily. A multivariate stat...

Human-health relevant impacts on marine ecosystems are increasing on both spatial and temporal scales. Traditional indicators for environmental health monitoring and microbial risk assessment have relied primarily on single species analyses and have provided only limited spatial and temporal information. More high-throughput, broad-scale approaches to evaluate these impacts are therefore needed...

The introduction of food waste disposers (FWDs) has been discussed in various countries, and Korea, a method for utilizing FWDs considered. results the study show that use is more eco-friendly economical than other forms (FW) disposal. However, there are also studies showing worse, example, they aggravate water pollution deteriorate function municipal wastewater treatment plants (WWTPs). Theref...
