The detection of SARS-CoV-2 RNA fragments in feces has paved the way for wastewater-based epidemiology to contribute COVID-19 mitigation measures, with its use a public health context still under development. As facilitate data comparison, this paper explores impact using alternative normalization approaches (wastewater treatment plant (WWTP) flow, population size estimates (derived total nitro...

The paper presents the results of an analysis of a two-stage pilot plant for the removal of toluene and benzene from the exhaust air of an industrial wastewater treatment plant (WWTP). The two-stage air process combines a water scrubber and a biotrickling filter (BTF) in sequence, and treats air stripped from the liquid phase compartments of the WWTP. During the experimental period, the pilot p...

Biological nitrogen removal (BNR) systems are increasingly used in the United States in both centralized wastewater treatment plants (WWTPs) and decentralized advanced onsite wastewater treatment systems (OWTS) to reduce N discharged in wastewater effluent. However, the potential for BNR systems to be sources of nitrous oxide (NO), a potent greenhouse gas, needs to be evaluated to assess their ...

In this paper, the reuse of reclaimed wastewater for irrigation of agricultural land and its effect on soil quality has been investigated in an arid region of Iran. For this purpose, two pilots of 2,000 m2 area with a variety of plants were selected near the effluent discharge of a wastewater treatment plant (WWTP) in Zahedan and Zabol cities in Sistan and Baluchestan Province. The wastewater t...

Sewerage systems-related solid waste accumulates in considerable quantities urban water systems, including rainwater drainage pipes, pumping stations, grease traps, grit chambers, and septic tanks. Traditional management methods, such as sanitary landfilling, incineration, composting, not only endanger the environment but also consume a significant amount of land. To address this problem, varie...

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...

In this study, the effluent reuse potential of 39 industrial wastewater treatment plants (WWTPs) in Taiwan was evaluated using grey relation analysis. A significant, consistent result was revealed. The WWTPs with the lowest reuse potential among 39 industrial parks were in the order: Gueishan, Tucheng, Nankang WWTPs. The WWTPs with highest reuse potential were as follow: Yungan > Tafa > Fongsha...

This study is carried out within the framework of requirements ensuring reliable operation Central Wastewater Treatment Plant Ulaanbaatar to increase treatment performance and mitigate adverse impacts current poor on nature ecology. The dynamic influent was studied in order find best-suited solution as a means improvement for WWTP. As an immediate fast-to-build solution, equalization tank pre-a...

The concentrations and removal efficiencies of various kinds of micropollutants were investigated and the relationships between the input sources of industrial wastewater and occurrence patterns of each micropollutant were identified at nine on-site industrial wastewater treatment plants (WWTPs). The distribution pattern of each compound varied according to the WWTP type and several micropollut...

Changes were assessed in urban wastewater treatment plant (WWTP) effluent quality during short-term storage in open surface ponds. Water quality was monitored over five years at the inlets and outlets of open storage ponds located at three biological nutrient removal plants. Pond influent temperature, rainfall and sewage inflow were not found to be major factors. However, there was a trend for ...
