The paper presents the sensitivity and uncertainty analysis of an integrated urban drainage model which includes micropollutants. Specifically, a bespoke integrated model developed in previous studies has been modified in order to include the micropollutant assessment (namely, sulfamethoxazole – SMX). The model takes into account also the interactions between the three components of the system:...

The potential for in situ biodegradation of 4-nonylphenol (4-NP) was investigated in three hydrologically distinct streams impacted by wastewater treatment plants (WWTPs) in the United States. Microcosms were prepared with sediments from each site and amended with [U-ring-(14)C]4-n-nonylphenol (4-n-NP) as a model test substrate. Microcosms prepared with sediment collected upstream of the WWTP o...

The tofu industry produces wastewater that can pollute the environment. One of solution is using Wastewater Treatment Plant (WWTP). WWTP will increase cost (investment and operational cost) for factory. However, it not revenue because use unrelated to production activities This research aimed analyze financial feasibility a factory with maximum in soybean prices labor wages. was conducted by ca...

In this study, performance estimation of biological wastewater treatment plants (WWTP) was made by applying Artificial Neural Network (ANN) techniques. As material, 355-day data from Adana Metropolitan Municipality Seyhan plant for 2021 were used. Of the used, 240 evaluated as training and 115 test data. establishment ANN model, daily chemical oxygen demand (COD), water flow (Qw) suspended soli...

Hypoxia (low oxygen) often occurs in aquatic ecosystems that receive effluent from municipal wastewater treatment plants (WWTP). The combination of hypoxia and WWTP could impair fish health, because contains multiple contaminants disrupt the physiological pathways use to cope with hypoxia, but interactive effects these stressors on physiology are poorly understood. We have examined this issue b...

Conventional wastewater treatment, primary and secondary treatment processes with simultaneous phosphorus precipitation, is the most common process combination used in Finnish wastewater treatment plants (WWTPs). It typically eliminates most of the organic load and phosphorus, as well as part of the enteric microorganisms present in raw wastewater. Municipal secondary effluents still contain so...

Abstract Water quality, treatment plant management, and environmental concerns all affect how well a sewage performs. Due to the high degree of nonlinearity in as nonuniformity unpredictability influent amount, quality parameters, operational conditions, modelling sludge capacity index activated method municipal wastewater plants is challenging mission. To assess effectiveness al-diwaniyah (WWT...
