A prototype dynamic model for the co-treatment of a high strength simple-organic industrial effluent and coal-mine drainage
… 2.5 or 5gCOD/l where both systems have the same effluent substrate concentrations. However, the difference in the comparative substrate utilisation rate is less at higher feed substrate concentrations. This is the influence of substrate inhibition on the active SRB biomass, which increases with …

The development of continuous automatic biological monitoring systems for water quality control
… has experienced an unprecendented degree of industrial expansion. Although this has enhanced the material wealth and personal comfort of all the nations' peoples, it has also produced an undesirable consequence - ever increasing pollution of the aquatic environment. Viable systems for …

Development of selective pre-concentration methodology of some of the platinum-group metals in acidic solutions, followed by their direct determination by ICP-OES
… complex, severely interfering matrices, such as industrial effluent, has been the focus of much research in_the past forty years. However, despite the greater availability of much improved instrumentation, such as ICP-OES, NAA and XRF, most analytical techniques currently employed for the …

Development of defined media for motility and for growth of Spirillum volutans, with special reference to biological monitoring of pollutants and to obligate microaerophilism of bacteria
… Spirillum volutans to detection of pollutants in industrial effluent for the purpose of in-plant biological monitoring. The other was a nutritional study of the organism with emphasis on its obligate microaerophilism. In the pollution monitoring project, flagellar uncoordination in S. volutans was …

Biological treatment and recycling of textile processing effluents
… culture system for the treatment of textile dye effluents. The bioprocess was optimised using biomass growth supports. The presence of a carbon source such as soluble wheat starch (0.2 % w/v) in dye solution media and effluent samples enhanced decolourisation. A polymer support (polyurethane …

Removal of nitrogen containing hydrocarbons from wastewater by catalytic and non-catalytic hydrothermal oxidation, in sub- and supercritical conditions
… were investigated for the treatment of hazardous industrial effluent with a high initial ammonia concentration and complete ammonia removal was achieved using Ru/Al\(_2\)O\(_3\) pellets. A novel ruthenium coated reticulated foam monolith was investigated as an alternative for heterogeneous …
