Photocatalytic pretreatment of oily wastewater from the restaurant by a vacuum ultraviolet/TiO2 system

Fat, oil and grease deposits in sewers: Characterisation of deposits and formation mechanisms

“…In-sewer processes are also reported to give up to 40% reduction in chemical oxygen demand during passage of water (Almeida et al, 2000) so this may be another factor influencing the high water quality measurements in initial sections of the sewer systems. However, similar levels of FOG and organic matter to this study have been reported in untreated wastewater from restaurants in South Korea, Hong Kong and mainland China (Nisola et al, 2009;Chan, 2010;Kang et al, 2011). Chen et al (2000) also found significant differences in the wastewaters from different types of restaurant, with high levels of FOG seen in "Western" food and a student canteen, there has been no similar systematic study of the wastewater from different take-away outlets in the UK.…”

Technology for Treating Oily Wastewater Derived from Various Industries: A Review Paper

“…Restaurant industry cannot be separated from urban development as it is main part of modern lifestyle for the community. This industry can have a significant amount of oily wastewater containing high oil and grease particles generated from its operational activities such as washing kitchen utensils, cleaning and cooking food materials [13]. In many developing countries, the oily wastewater generated by restaurant industry mostly flows into foul sewers.…”

Advanced Bioreactor Treatments of Hydrocarbon-Containing Wastewater

“…Depending on wastewater characteristics and operational conditions, the AOP converts recalcitrant organic components into lower molecular weight compounds, which are more amenable to biological degradation and hence an easier decomposition in a biological treatment plant can be achieved. Kang et al [73] applied a vacuum ultraviolet (VUV, 185 nm) and TiO 2 oxidation system for the pre-treatment of oily wastewater. The results indicated that the VUV/TiO 2 process reduced significantly COD, BOD and oil content and improved the biodegradability of oily wastewater, thus paving the way for subsequent biological treatment.…”
