The applicability of advanced treatment processes in the management of deteriorating water quality in the Mid-Vaal river system
(2015)The main objective of this study was to determine the applicability of advanced water treatment processes namely granular activated carbon (GAC) adsorption, ultraviolet (UV) light disinfectant and ozone in the management ... -
The effect of pre-ozonation on the physical characteristics of raw water and natural organic matter (NOM) in raw water from different South African water resources
(North-West University, 2006)Research in the use of ozone in water treatment conducted by many authors support the idea that the nature and characteristics of natural organic matter (NOM) present in raw water determines the efficiency of ozonation ... -
Liberation of chromium from ferrochrome waste materials utilising aqueous ozonation and the advanced oxidation process
(2014)During ferrochrome (FeCr) production, three types of generic chromium (Cr) containing wastes are generated, i.e. slag, bag filter dust (BFD) and venturi sludge. The loss of these Cr units contributes significantly to the ... -
Ozone treatment of chromium waste materials
(North-West University, 2011)Ozonation, or advanced oxidation processes (utilising ozone decomposition products as oxidants) are widely used in industrial waste water and drinking water treatment plants. In these applications the use of ozone is based ...
