A study of comminution in a vertical stirred ball mill.
A 20 litre experimental batch and continuous test rig and 5 litre batch and 50 litre continuous test rigs for stirred ball milling were built at the University of Natal and Mintek respectively. All the mills featured a ...

Mathematical modelling and experimental study of the kinetics of the acid sulphite pulping of eucalyptus wood.
The chemistry of the batch cooking process at Sappi Saiccor, relating to both the pulp and liquor, was investigated with the aim of using kinetic expressions to develop an improved process control model. The mill produces ...
A study of the phenomenon of bridging of sugarcane bagasse
This work reports the results of a systematic study of the factors that affect the bridging behaviour of bagasse. It shows that traditional bulk solids theory is inappropriate for predicting bagasse flow mainly because ...
Measurement and thermodynamic interpretation of high pressure vapour-liquid equilibrium data.

The recovery of sodium hydroxide from cotton scouring effluents.
This dissertation describes the characterisation of, and development of a novel integrated waste management strategy for, hydroxide scouring effluents produced during cotton processing. Such effluents are typical of ...
Residence time methods for modelling and assessing the performance of water treatment processes.
The objective of this study was to provide a technique, based on the residence time distribution of a process, for modelling, assessing and improving flow in the processes of water and waste water treatment works. ...
Performance studies of the tubular filter press.
The tubular filter press is a novel tubular configured filter press for the filtration or dewatering of sludges. The unique features of the filter press are: (i) during the cake deposition cycle, cake is deposited on ...
Municipal wastewater characterization : application of denitrification batch tests.
The biological treatment of wastewater has evolved significantly from simple single sludge systems practicing organic carbon removal to ones which now include either nitrification/denitrification (N/DN) and / or phosphorus ...
