Calcium peroxide

TL;DR: CaO2 was a more efficient oxidant than liquid H2O2 at all pH values because it only releases H2 O2 upon dissolution, reducing the loss to O2 and volatilization.

TL;DR: Experimental results and model-based analysis suggested that CaO2 pretreatment increased the maximum methane yield and methane production rate, which were consistent with the analysis above.

TL;DR: Developing a promising technology to produce a valuable carbon source from WAS by exploiting the effect of CaO2 addition on anaerobic fermentation of waste activated sludge and the conversion of other SCFAs to acetic acid.

TL;DR: D density functional theory calculation was in good agreement with the experimental results, which proved that the Fe2+/OA/CaO2 could improve the circulation between Fe2- and Fe3+, promoting the oxygen reactive species generation and pollutant removal.

TL;DR: It was found that sludge filtration performance was enhanced by calcium peroxide oxidation with the optimal dosage of 20 mg/gTSS, but this enhancement was not observed at lower dosages due to the absence of oxidation and the performance deteriorated at higher dosages because of the release of excess EPS.
