Aspects of the chemistry of some persistent organic contaminants and their removal from river and wastewater
(The University of Waikato, 2001)Liquid/liquid extraction, glass fibre and 3-0.05 µm filtration and SIM-GC/MS procedures were used to determine the levels of free and particle bound resin acids in Tarawera River water samples collected at the State Highway ... -
The development and applications of a micro-gap perforated electrode flow through cell
(University of Waikato, 2011)Electrochemical techniques provide convenient and environmentally compatible ways of bringing about chemical transformations. However they generally lose their economic viability when used with low conducting electrolyte ... -
Electrolytic purification of water
(The University of Waikato, 2006)This thesis develops the concept of an in situ electrolytic processor, a machine with electrochemical functions that purifies aqueous fluids at the point of production, whether from a bore water supply or effluent from a ... -
Evaluation of granular media to wastewater treatment; advanced primary treatment utilising modified pumice, titanomagnetite and ceramic nozzles.
(The University of Waikato, 2002)The treatment of wastewater to higher standards is becoming increasingly important as legislation and public perception demand reduced impact of human activity on the environment. Filtration of primary treated effluent ... -
Preparation of mesoporous solids containing encapsulated metal species of technological interest
(University of Waikato, 2011)The advent of mesoporous silicas such as MCM-41 has provided new opportunities for research into supported metal catalysis. The loading of metals into framework structures and particularly into the pores of porous molecular ... -
Studies of anodising sludge and its uses
(The University of Waikato, 2008)Anodising is an important finishing technique used to produce controlled oxide coating on aluminium extrusions which impart aesthetic finish, longer life and resistance to corrosion and abrasion. The anodising process ... -
Studies of Bore Water Oxidation Using a Multi Electrode-Perforated Electrode flow Through Cell
(University of Waikato, 2012)Anoxic groundwaters in the Waikato region are naturally contaminated with iron and manganese at levels of 25.0 mg/L and 0.9 mg/L respectively and above. Often these contaminants can be removed by simple aeration and ... -
Studies of sludge collected from the anaerobic digester of a meat processing company
(The University of Waikato, 2010)Anaerobic digestion is commonly used as a wastewater treatment step where complex biological substrates are progressively degraded in the absence of oxygen to produce methane and carbon dioxide with hydrogen and volatile ...
