The formation of Disinfection By-Products (DBPs) in drinking water results from the reaction of chlorine or other disinfectants added to the water with naturally occurring organic materials, and has raised concerns during the last decades because these compounds are harmful for human health. During...

Chloroform and other bromochlorotrihalomethanes were first identified as disinfection byproducts (DBPs) in chlorinated water in 1970s. Since then, many other DBPs have been identified such as haloacetonitriles, haloacetaldehydes, cyanogen halides, aldehydes, ketoacids, chlorite, bromate and other...

The goal of this paper is an investigation into the influence of disinfection with ozone, chlorine (Cl2) and chlorine dioxide (ClO2) on the aldehydes formation. Three types of waters were treated with different doses of these disinfectants. The results obtained indicate that the level of carbonyls...

This paper discusses current issues with drinking water disinfection by-products (DBPs), which include emerging (unregulated) DBPs that can be formed at greater levels with alternative disinfectants (as compared to chlorine) and routes of human exposure (which include inhalation and dermal exposure...

MX (3-Chloro-4-(Dichloromethyl)-5-Hydroxy-2(5H)-Furanone) and NDMA (N,N-dimethyl-Nnitrosoamine) are disinfection by-products, which are formed during NOM’s and other water containing precursors reaction with chlorine. Both, due to their potential carcinogenic and mutagenic properties were placed on...
General
(NMEA) and N-nitrosodiethylamine (NDEA) are highly mutagenic compounds that are suspected of carcinogenic activity to the human body. The aim of the paper is the evaluation of the possibility of N-nitrosomethylethylamine and N-nitrosodiethylamine formation as a result of the reaction of...

Photocatalysis by titanium dioxide (TiO2) is a water treatment method. Pseudomonas aeruginosa is a microorganism resistant to chlorine and UV-C irradiation. TiO2 photocatalytic technology can destroy bacteria, which are resistant to oxidative destruction of cell membrane caused by sole UV...
