Preliminary Information

Abstract The degradability of two commercially available pesticides was studied using heterogeneous photocatalytic and activated sludge treatment methods. The first pesticide contained 5% quizalofop-P-ethyl as an active ingredient and petroleum naphtha as a solvent, the latter causing difficulties both in photocatalytic and biological treatment methods. The active ingredient of the second compound was acetamiprid. The photocatalysis proved to be effective both under laboratory conditions (using UV light) and when exposed to sunlight, but the pesticides remained stable during the employed biological treatment. Preliminary information on its behaviour in soil was obtained from transport modelling.

Gas To Liquid

Gas-to-liquid (GTL) technology involves the conversion of natural gas into several liquid hydrocarbon products. The Fischer–Tropsch (F–T) process is the most widely applied approach for GTL, and it is the main source of wastewater in the GTL process. The wastewater is generally characterized by high chemical oxygen demand (COD) and total organic carbon (TOC) content due to the presence of alcohol, ketones and organic acids. The discharge of this highly contaminated wastewater without prior treatment can cause adverse effects on human life and aquatic systems. This review examines aerobic and anaerobic biological treatment methods that have been shown to reduce the concentration of COD and organic compounds in wastewater. Advanced biological treatment methods, such as cell immobilization and application of nanotechnology are also evaluated. The removal of alcohol and volatile fatty acids (VFA) from GTL wastewater can be achieved successfully under anaerobic conditions. However, the combination of anaerobic systems with aerobic biodegradation processes or chemical treatment processes can be a viable technology for the treatment of highly contaminated GTL wastewater with high COD concentration. The ultimate goal is to have treated wastewater that has good enough quality to be reused in the GTL process, which could lead to cost reduction and environmental benefits.

Abstract This paper presents a review of North American and European literature concerning the physical and chemical characteristics of leachate and the biological treatment methods that have been used or could be used to treat leachate. Leachate characteristics of particular interest include five-day biochemical oxygen demand (BOD5) , chemical oxygen demand (COD), the BOD5/COD ratio, molecular weight and or size of the organics, volatile fatty acids (VFA’s), ammonia and metals. It is demonstrated that biological leachate treatment is most appropriate when the BOD5/COD ratio is high (i.e. > 0.4) and the molecular weight of the majority of the organics is less than 500 g/mole. Tables summarizing the various biological leachate treatment process loading rates are presented. This paper serves as the basis for two companion papers: ”Selection of the Most Appropriate Leachate Treatment Methods, PART 2 : A Review of Recirculation, Irrigation and Potential Physical-Chemical Treatment Methods” and “Selection of the Most Appropriate Leachate Treatment Methods, PART 3: A Decision Model for Treatment Train Selection”.
