Abstract The presence of toxic algae, such as Microcystis aeruginosa (MA), in drinking water treatment plants (DWTPs) would contribute to algal organic matter (AOM) precursors toward disinfection by-products (DBPs). Electrocoagulation–flotation (ECF) has shown promising performance minimizing cells from and dissolved AOM. This study aimed investigate the effect current density (CD) pH on alumin...

The formation of toxic nitrogenous disinfection byproducts (N-DBPs), such as nitrosamines, halonitromethanes and haloacetonitriles, from reactions between chlorine/chloramine and dissolved organic nitrogen in drinking water has caused great concern with regarding public health. This study revealed the occurrence of 17 aliphatic amines, some of which have been confirmed to be the precursors of N...

Chlorination is the most popular method for disinfecting swimming pool water; however, although pathogens are being killed, many toxic compounds, called disinfection by-products (DBPs), are formed. Numerous epidemiological publications have associated the chlorination of pools with dysfunctions of the respiratory system and with some other diseases. However, the findings concerning these associ...

Ozonation followed by biological activated carbon (O3/BAC) is being considered as a key component of reverse osmosis-free advanced treatment trains for potable wastewater reuse. Using a laboratory-scale O3/BAC system treating two nitrified wastewater effluents, this study characterized the effect of different ozone dosages (0-1.0 mg O3/mg dissolved organic carbon) and BAC empty bed contact time...

Electrochemical oxidation (EO) using boron-doped diamond (BDD) electrodes attracted increasing interests due to its high efficiency in mineralizing chlorinated organic pollutants water. However, it produces hazardous disinfection by-products (DBPs) including chloramines, chlorate and perchlorate ions discharges acidic streams. In this work, an attempt neutralize the effluent reduce production o...

The supply of safe drinking water to rural communities has always been challenging, unlike in most large cities where government authorities have constructed central systems. In many areas, primary sources such as surface and groundwater are at risk contamination with rapid agricultural industrial growth climate change-related issues. Rainwater harvesting is an ancient practice for communities,...

Providing safe tap water while limiting the occurrence of disinfection by-products (DBPs) is probably one most challenging aspects environmental chemical engineering within urban cycle. In present work, an investigation about this challenge for real conditions a full-scale drinking treatment plant has been carried out. Five different and well-known technologies (four aeration procedures, coagul...

Brominated phenols (BPs), a widely used group of emerging flame retardants, are important environmental contaminants and exhibit endocrine disrupting potential. Method for simultaneous determination of tetrabromobisphenol A (TBBPA), tribromophenol (TBP), dibromophenols (DBPs) and monobromophenols (MBPs) in soils using gas chromatography-mass spectrometry analysis (GC/MS) was successfully develo...

Medium pressure UV is used for controlling the concentration of combined chlorine (chloramines) in many public swimming pools. Little is known about the fate of other disinfection by-products (DBPs) in UV treatment. Photolysis by medium pressure UV treatment was investigated for 12 DBPs reported to be found in swimming pool water: chloroform, bromodichloromethane, dibromochloromethane, bromofor...
