Opis:: The paper provides an account of uses where advanced oxidation processes(AOP)are applicable,particular consideration being given to the removal of hazardous pollutants from water taken in for municipal supply.Examples of AOP development are given as well.The general principle of the AOPis to form highly reactive free radical (specifically hydroxyl radicals) in the aqueous medium.To produce these species use is made of ozone,hydrogen peroxide,UV radaition,catalysts (TiO2,MnO2,Fe2+)-single of in combinations-if beneficial synergetic effects are abserved.The mechanisms governing the AOP process,as well as a variety of engineering applications, are discussed in detail.The AOP is particularly useful in removing non-biodegradable water pollutants which are resistant to conventional treatment.

Opis:: The paper provides a critical review of recent publications on how bromates form and how the available water treatment methods can minimize their concentrations. From this review it cast be concluded that the molecular and radical mechanisms governing tJie reactions of bromine compounds with ozone in the aquatic environment are quite well understood. They all evidence the complex character, as wellas the potential influence of the process parameters involved on the extent of these reactions and the conversion of bromides into bromates. This finding holds particularly for the water matrix which is treated with ozone or for the advanced oxidation processes which are in use now. Many investigators concentrated upon the problem of how to abate the bromate levels accounted for by the complex reactions of bromine compounds with oxidants (ozone, hydrogen peroxide, catalysts) as well as UV irradiation, and how to provide efficient removal of those pollutants from the treated water. In this context, the papers by the Dutch researchers [12-15] and the study by Von Gunten et al. [6] deserve particular attention, They show that it is possible to optimize the treatment process so as to meet the disinfection requirement, to remove the micropollutants (mainly pesticides) from the water, and to keep th& concentration of bromine within the allowable range. The authors mentioned emphasize not only the potentiality for achieving good treatment effects when using hydrogen peroxide, but also some advantages resulting from the application of UV irradiation and catalytic processes [TiO2, synergetic effects of Fe ani Mn removal).
