Wastewater can be defined as the flow of used water discharged from homes, businesses, industries, commercial activities and institutions which is directed to treatment plants by a carefully designed and engineered network of pipes. This wastewater is further categorized and defined according to its sources of origin. Growing population and industrial development have increased wastewater generated by urban areas and otherwise. Industrial wastewater is a complex organic and inorganic liquids and can have enormously adverse environmental impacts, depending upon the characteristics of the materials that exist in them. In general, the pollutants in wastewater could be divided into organic matter and inorganic matter which included nitrogen, phosphorus, ammonia and iron chlorides as well as heavy metals. On the other hand, landfill leachate is a concentrated wastewater which is rich in organic compounds which could also pose risk to the health of both humans and living things. Advanced treatment is necessary to treat hazardous chemicals and landfill leachate as they contain high concentrations of recalcitrant organics and organic material. The selection of an appropriate treatment strategy is often not easy. Therefore, in order to meet the standards, suitable treatment alternatives should be established.
Ozonation is one of the advanced oxidation processes (AOP’s), commonly used by industry. Recently ozonation has been given significant attention in the treatment of concentrated wastewater and landfill leachate as the process could increase the oxidation potential and reduce the treatment time in the pre or post-treatments stage. Combination of ozone and other treatment techniques have also been investigated by many workers. Although ozone is quite effective, however there are many aspects that could be further enhanced in improving the treatment efficiencies. Therefore, the papers of this special issue will address research on advanced oxidation processes by ozonation for wastewater and landfill leachate treatment.
Suitable topics include, but are not limited to, the following:
- Critical review
- Combination of ozone and other advanced oxidation processes (AOP) processes
- Sequential and simultaneous ozonation processes
- Combination of ozonation with physical and chemical treatments
- Biodegradability improvement of landfill leachate
- Influence of ozonation on leachate compositions
- Pre and post ozonation processes
- Chemical reactions and mass balance during ozonation
- Modelling and computation
- Catalytic ozonation
- Design
- Other related topics of ozonation
