Disinfection by-products

In this study, aluminium sulphate (alum) and polyaluminum chloride (PAC) coagulation were used for coagulation of different origin water (Buyukcekmece, BC and Omerli, OM in Istanbul, Turkey and Carmine, CR in Salerno, Italy) treatment. The effect of pre-ozonation alone and combined with coagulation

Effective use of chlorine dioxide as an alternative disinfectant in water treatment may require removal of the by! product chlorite ion (ClO2 ). The goal of this research was to investigate the use of ferrous iron (Fe2+) for the chemical ! reduction of ClO2 from drinking water in order to define the

Two different procedures, respectively aiming at the best allocation and managing of disinfection stations along water distribution systems, are presented, with the main objective of proposing a criterion to limit chlorine and disinfection by-product concentrations in the drinking water supplied to

The chlorination of water containing natural organic matter (NOM) and bromide leads to the formation of total trihalomethanes (TTHMs), for which the Italian new regulation on drinking water (Legislative Decree 31/01) indicates a restrictive maximum concentration level of 30 µg/l. The extent of total

An investigation into the occurrence of disinfection by-products (DBPs) was conducted for a period of two years (2001–2002) on the drinking water of Athens, Greece. Samples from four water treatment plants (WTPs) and from the distribution system of Athens were collected monthly and analyzed for DBPs

This paper reports the experimental results of a pilot-scale (100 m3/h) investigation, carried out at the West Bari (S. Italy) municipal wastewater treatment plant, focused on parasite removal and disinfection by-product (DBP) formation during the UV disinfection of clarified (CL) and clarified-filt
