“…The results points out that the sludge shall be ozonated first, and then be treated with H 2 O 2 and RF heating. Duguet et al (1985) also reported that for a combination of ozone-hydrogen peroxide treatment, H 2 O 2 shall be introduced into solution after the oxidation of substances with O 3 alone to achieve the best performance. It shall also be noted that the COD results were comparable to previous microwave studies (Yin et al, 2007).…”

Microwave-oxidation treatment of sewage sludge using various oxidants was studied. Two treatment schemes with a combination of hydrogen peroxide and ozone were examined: hydrogen peroxide and ozone were introduced into the sludge simultaneously, followed by microwave heating. The other involved the ozonation first, and then the resulting solution was subjected to microwave and hydrogen peroxide treatment. The set with ozonation followed by hydrogen peroxide plus microwave heating yielded higher soluble materials than those of the set with hydrogen peroxide plus ozone first and then microwave treatment. No settling was observed for all treatments in the batch operation, except ozone/microwave plus hydrogen peroxide set at 120°C. The pilot-scale continuous-flow 915 MHz microwave study has demonstrated that microwave-oxidation process is feasible for real-time industrial application. It would help in providing key data for the design of a full-scale system for treating sewage sludge and the formulation of operational protocols.

“…[41][42][43][44][45] Chlorination of water in swimming pools, which contains nitrogen-containing compounds such as urea and amino acids, also contributes to nitrogeneous disinfection byproducts (N-DBPs) formation. [46][47][48] The production of N-DBPs from the chlorination of Microcystis aeruginosa, a source of toxic microcystins, has also been proposed. [49] Recently, monochloramine (NH 2 Cl) has also been applied as a chlorine alternative in order to reduce DBPs formation in water treatment systems.…”

Disinfection byproducts (DBPs) in drinking water exhibit considerable adverse health effects; recent focus is on the brominated disinfection byproducts (Br-DBPs). The chlorination and chloramination of bromide ion containing water produce reactive bromo species, which subsequently react with natural organic matter (NOM) to yield Br-DBPs. The possible reactions involved in generating DBPs are presented. Identified Br-DBPs include bromomethanes, bromoacetic acid, bromoacetamides, bromoacetonitriles, and bromophenols. Mixed chloro- and bromo-species have also been identified. Pathways of the formation of Br-DBPs have been described. The concentration of Br- ion, pH, reaction time, and the presence of Cu(II) influence the yield of DBPs. The effects of water conditions on the production of Br-DBPs are presented. The epidemiological studies to understand the potential toxic effects of DBPs including Br-DBPs are summarized. Brominated DBPs may have higher health risks than their corresponding chlorinated DBPs. A potential role of an emerging alternate disinfectant, ferrate (FeV)O(2-)4), in minimizing DBPs is briefly discussed.
