Advanced Oxidation Processes (AOPs) have been employed to degrade biorefractory organic matters. This study investigates the combination of classical Fenton reaction with electrochemical oxidation, the electro-Fenton process, for the treatment of semi aerobic landfill leachate, collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. The investigation has been carried out in batch re...
During recent years, many advanced oxidation techniques have been investigated for water and wastewater treatment to overcome the shortage of clean water. This review summarizes the background and principles of photocatalysis applied as an advanced oxidation technology. In particular, this paper focuses on modification of photocatalysts with various dopants as well as the novel photocatalytic r...
In the present study, advanced oxidation treatment, UV/ was applied to decolourisation of Acid Orange 8 (AO8). The UV radiation was carried out with a 15 W low-pressure mercury lamp. Kinetic model for the decolourisation of the dye was developed based on experimental results and known chemical and photochemical reactions. The observed kinetic reaction constant was determined and correlated as a...

Potentially harmful disinfection byproducts (DBPs), as a significant challenge in water treatment, are formed when oxidizing disinfectants react with natural organic matters (NOM). Unfortunately, an unwanted side effect is the formation of harmful by-products, such as THMs and HAAs, following the chlorination stage. DBPs cause a variety of diseases like cancer in humans. In this ...
the saline tannery wastewater also contains the high concentration of organic materials and various chemical compounds like lime, sodium sulfite, sulfate ammonium, sodium chloride, disinfections, vegetable tannins, salts of chromium and chloride. in recent years different applications of advanced oxidation processes (aops) are applied to remove organic loading (cod) from wastewater. advanced ox...
aims: in biological wastewater treatment processes, a large amount of sludge is produced. stabilization of sludge is essential before disposal because of the risks to human health and environment. therefore, selecting an appropriate process for stabilization this sludge may efficiently decrease risks. the aim of this study was to examine the compound efficiency of the advanced fenton and ozonat...
conclusions changes of ph could remarkably affect the efficiency and oxidation rate of mtbe. in particular, the amount of kap in terms of oxidation declines substantially by moving away from the optimum ph range. in this study, ph 3.5 was considered as the optimal ph in h2o2/nzvi/ultrasonic oxidation process, with the elimination of about 89.56% of the high mtbe concentration. in general, we ca...
