Optimization and mechanism of copepod zooplankton inactivation using ozone oxidation in drinking water treatment
Bench-scale experiments were carried out to optimize ozone oxidation conditions for copepod inactivation by response surface methodology. Independent variables were ozone dosage (1, 3 and 5 mg/L), contact time (5, 15 and 25 min) and organic matter concentration (2, 5 and 8 mg/L). The results showed that all independent variables significantly influenced copepod inactivation rate. The observed ...

Rostock Water Works, Rostock, Germany: Drinking Water Ozone Plant
Ozone is the ideal agent for treating and disinfecting drinking water. The advantages of ozone and the improvement in the quality of the water after ozonation are evident at the Rostock Drinking Water Works following its modernisation. By specifying the new Advanced Technology from Ozonia, the Rostock Water Supply Company became the first user in Germany of high-tech ozone generation equipment ...

Optimization of the ozone dosage at the drinking water treatment plant of Kluizen
De Watergroep, a Flemish drinking water utility, aims to optimize the ozonation process at the Kluizen surface waterworks in order to obtain sufficient inactivation of pathogenic micro-organisms while minimizing the formation of bromate. In literature, the inactivation of micro-organisms is described as a first order process in ozone exposure (ozone concentration multiplied by exposure time or ...

Simulation of NOM events in pilot plant evaluation of DAF/Ozone/BAC for drinking water treatment
Pilot plant testing is invaluable for ascertaining the robustness of water treatment processes against raw water quality events such as turbidity and colour spikes, whether it be for stress testing of an existing process or designing of a new process. Unfortunately, the natural occurrence of such events (particularly colour) can be difficult to predict and commercial humic materials generally ...

Profiles of dissolved organic matter and haloacetic acid formation potential in drinking water treatment by a comprehensive fractionation technique
A comprehensive fractionation technique was applied to a set of water samples obtained along a real drinking water treatment plant with ozonation and granular activated carbon (GAC) treatment to obtain detailed profiles of dissolved organic matter (DOM) and to evaluate the haloacetic acid (HAA) formation potentials of these DOM fractions. The results indicated that ozonation and GAC treatment ...

Ozone disinfection: main parameters for process design in wastewater treatment and reuse
Wastewater disinfection by ozone was investigated at pilot and full scale on different wastewater effluents and two types of ozone reactors. It was demonstrated that water quality and, in particular, suspended solids and organic content strongly influence the required ozone dose for a given level of disinfection. The increase in contact time and residual ozone concentration did not improve the ...

Advances in Bromine Speciation by HPLC/ICP-MS
Bromine is a natural component found in waters, most commonly as the bromide ion, Br-. A common procedure for purifying drinking waters is treatment with ozone to kill bacteria. A byproduct of ozonolysis is the conversion of bromide to bromate (BrO3-), a known carcinogen. Therefore, a need exists to measure both bromide and bromate in drinking waters, as opposed to total bromine content. Our ...
