Abstract Water pollution is still a serious problem in Indonesia. One of the pollutants that contribute to water dye. type dye often used textile industry methylene blue. There are several methods for treating waste, one which ozonation method. Ozonation chemical oxidation process remove color organic dyes. The catalytic can increase ability ozone sewage treatment. catalyst H 2 O decompose into...

Background and purpose: In activated sludge process large amounts of sludge are produced. The disposal and management of this sludge remains a big challenge due to environmental, economic, social and legal factors. Thus, selecting an appropriate process that could reduce sludge would be of great help in solving this problem. The aim of present research was to determine the effects of three pr...

The treatment by advanced oxidation processes (AOPs) of waters contaminated by organic pollutants and containing also innocuous bromide ions may generate bromate ions as a co-product. In the present work heterogeneous photocatalysis and ozonation have individually been applied and in combination (integrated process) to degrade the organic compounds in water containing also bromide anions. The r...

The heterogeneous ozonation of suspended malathion and chlorpyrifos particles are studied in real-time with a vacuum ultraviolet photoionization aerosol time-of-flight mass spectrometer (VUV-ATOFMS). The pesticide particles with the diameter of hundreds of nanometers are generated by the homogeneous nucleation method using azelaic acid as nucleus. The reactions are carried out in an aerosol rea...
