Total nitrogen (TN) and total phosphorus (TP) concentrations are important parameters to assess the quality of water bodies and are used as criteria to regulate the water quality of the effluent from a wastewater treatment plant (WWTP) in Korea. Therefore, continuous monitoring of TN and TP using in situ instruments is conducted nationwide in Korea. However, most in situ instruments in the mark...

Hydrogen sulfide, which is produced by sewer biofilms as a result of sulfate reduction under anaerobic conditions, has since long been identified as a major cause of corrosion and odour problems in a sewer system. Dosing of various types of chemicals to wastewater is widely used by the water industry as a control measure for these problems. Oxygen/air, nitrate salts, iron salts and magnesium hy...

Introduction: Although various liquid, solid, and gaseous streams of wastewater treatment plants (WWTPs) have been analyzed in many studies for the presence of SARS-CoV-2 RNA, no study was found to sample and detect SARS-CoV-2 RNA in screenings and grit samples separated from primary treatment units of WWTP. Hence, this study aims to provide an experimental protocol for sampling and extracting ...

According to a recent report by the Iranian industrial organization, over 1700 Industrial and Engineering Brick Manufacturing (IEBM) industries are currently running in Iran, using the same method in common use worldwide. The present research study used a combination of a literature review, existing research reports, and a model of assessment among the four main kinds of IEBM industries to esti...

In this paper, we present WWTP(Wireless Waiting-Time Priority) to provide relative delay differentiated service in a wireless network where packets are classified into one of the ordered classes according to their relative delay requirements. WWTP ensures that a packet of higher class to enjoy better QoS(Quality of Service) than that of lower class unless it suffers from wireless channel errors...

evaluation and modeling of the wastewater treatment plants (wwtp) have to be based on thefact that the pollutant concentrations and flow rates change constantly. in addition, different approaches mustused due to there are different processes in a wwtp. a mexican petrochemical complex has a wwtp thatprocesses wastewaters from several petrochemical plants, where the flow rates and pollutant conce...

The aim of this study was to quantify the amount of polybrominated diphenyl ethers (PBDEs) released into the environment (biosolids, effluent) from a conventional Australian activated sludge treatment wastewater treatment plant (WWTP). The concentration of PBDE congeners was measured at various treatment stages and included four aqueous samples (raw, primary, secondary and tertiary effluents) a...

OBJECTIVE The goal of the current study was to gain insight into the prevalence and concentrations of antimicrobial resistant (AMR) Escherichia coli in Dutch surface water, and to explore the role of wastewater as AMR contamination source. METHODS The prevalence of AMR E. coli was determined in 113 surface water samples obtained from 30 different water bodies, and in 33 wastewater samples obt...
