The latest European Directive 98/83/CE (5 December 1998), concerning the quality of water intended for human consumption, has set a two-stage parametric value for bromate. Bromate concentration will comply with 25 μg/L after December 25, 2003, and w

Conditions for theoretical inactivation of Cryptosporidium by ozone could be achieved at full-scale facilities if their design is appropriate. To perform this task correctly the chemical engineer's approach for process design must be applied. This pa

A method based on a continuous operating ozone reactor is proposed which allows the determination of two fundamental parameters: the instantaneous ozone demand (X) and the ozone decay (k) for different types of water. An example of ozone reactor calc

This paper presents a simplified kinetic reaction rate model which enables the evaluation of various contactor hydraulics on bromate ion formation. Two extreme reactor types are presented: completely stirred tank (CSTR) and plug flow reactors (PFR).

Sorption of the organic pollutants phenol, 2,4,5-trichlorophenol, and tannic acid (Fluka) onto montmorillonite-based sorbents was studied. The sorbents were homoionic Na- or Ca-montmorillonite, montmorillonite completely exchanged with the cationic o

The U.S. EPA published the surface water treatment rule which imposed stringent requirements for disinfection. The rule is based on the C × T concept. The detention time T10 must be determined for each type of contactor by performing tracer tests. T

A study of chlorine modelling in sand filtered water (before postchlorination) of the Macao treatment plant indicates that the chlorine consumption in sand filtered water can be divided into two phases: an initial chlorine consumption during the firs
