摘要:Abstract(#br)The influence of reactor scale, impeller tip speed and specific power on the overall homogeneity (multi-phasic mixing) of two dimensionally similar stirred tanks of 50 mm and 220 mm internal diameter (ID) are compared using data collected from electrical resista...

摘要:Abstract(#br)The co-disposal of coal waste rock with fine benign waste can potentially aid in the prevention of acid rock drainage (ARD) by restricting the access of oxygen and water to sulfide bearing rock surfaces. However, in prevention studies, optimising the packing density ...

摘要:Abstract(#br)The co-disposal of desulfurised tailings, prepared from coal fines, with sulfidic coal interburden was investigated for the long-term prevention of ARD under extreme oxidative conditions. Benign tailings, comprising less than 0.78 wt% sulfur and classified as non-aci...

摘要:Abstract(#br)Conventionally, filtration and centrifugation are used to separate yeast from suspensions. Mini hydrocyclones (10 mm diameter) have previously been shown to achieve limited dewatering of non-flocculating Bakers’ yeast. This indicated the potential of the applica...

摘要:Abstract(#br)By monitoring cell yield and fermentation products during fed-batch and continuous growth, Pfaffia rhodozyma was shown to exhibit the Crabtree effect. In fed-batch culture at feed concentrations of 27 and 55 g glucose/l there was good agreement between the observed b...

摘要:Abstract(#br)Electronic waste (e-waste) contains a wide range of elements, many of which are highly toxic to environmental and human health. On the other hand e-waste represents a significant potential source of valuable metals. This study used microbial oxidation of pyrite ...

摘要:Abstract(#br)Mini-hydrocyclones were used to effect differential separation of a leached slurry of sulphidic ore from a continuous bioleaching process. Separations of the sulphidic ore, other non-biological solids as well as free and attached bacteria were studied. The volumetric...

摘要:Abstract(#br)It is well recognised that the product of sulphate reduction, i.e. the sulphide species formed, may inhibit the biological process. In this paper, we further the kinetic study of biological sulphate reduction using the mixed population of complete oxidisers grow...

摘要:Abstract(#br)The oxygen transfer rate (OTR) is a key parameter in aerobic bioprocesses, and in particular, in hydrocarbon-based bioprocesses where a proportionately higher rate is required due to the oxygen deficient structure of the substrate. The OTR is dependent on the ox...
