Stickiness of faecal sludge for drying applications.
(2021)Faecal sludge management (FSM) seeks to achieve safe disposal of faecal sludge with minimum risks to the environment and overall human population with the possibility of attaining resource recovery. Thermal drying is a ... -
Sulphonated carbon catalyst for biodiesel synthesis.
(2021)The uncertainty surrounding the sustainability of petroleum and petroleum derived products along with efficient waste management methods and the increasing energy demands are of great concern in modern society. As a result, ... -
Catalytic pyrolysis of plastic waste to produce diesel-like fuel.
(2021)Over the years, plastic generation and usage have increased due to plastics' favourable properties for domestic and industrial purposes. Plastics are cheap to manufacture, durable, flexible, resistant to moulding and rust, ... -
Slurry-phase desulphurization of tyre derived oil using unsupported and supported alkaline earth metal oxides.
(2021)The global consumption of tyres continues to increase to meet industrial, commercial, and personal transportation needs, which means that more tyres reach end-of-life. There are various methods of dealing with waste tyres, ... -
Thermo-physical properties of alkanolamine-ethanol hybrid solutions: experimental measurements and modelling.
(2021)This study presents the measured densities (!), viscosities (") and refractive indices (nD) of Monoethanolamine (MEA) + Ethanol (ETOH), N-Methyldiethanolamine (MDEA) + ETOH and Diethanolamine (DEA) + ETOH mixtures over ... -
Optimisation of sludge management in eThekwini Municipality.
(2022)Sewage sludge processing for use or disposal has been a continuing challenge for many municipalities within South Africa. The main challenges encountered are the operation complexity and environmental impact posed by sewage ... -
Production of engine biolubricant oil from non-edible vegetable oil through chemical modification and formulation.
(2021)Recently, the 26th Climate Change Conference (COP26) has pledged R130 billion to assist South Africa in transitioning to environmentally friendly energy sources. Some of the funds are being allocated to developing new ... -
Separation of binary homogeneous azeotropic mixtures using pervaporation.
(2021)The separation of mixtures containing homogeneous azeotropes is often complex and requires the use of enhanced distillation techniques. This leads to a significant increase in capital and operating costs. The use of membrane ... -
Application of graph theory to resource distribution policy-based synthesis of industrial symbiosis networks.
(2021)Industrial symbiosis (IS) involves the repurposing of waste and by-product streams from one chemical industry as feedstock to another. Given the growing environmental and economic concerns, it has become increasingly ... -
Thermo-physical properties of alkanolamine-ethanol hybrid solutions: experimental measurements and modelling.
(2021)This study presents the measured densities (!), viscosities (") and refractive indices (nD) of Monoethanolamine (MEA) + Ethanol (ETOH), N-Methyldiethanolamine (MDEA) + ETOH and Diethanolamine (DEA) + ETOH mixtures over ... -
Design and optimization of a separation process for butanediol dehydration for use as a biofuel.
(2020)Ongoing research in incorporating renewable biofuels into the transport sector are fuels that can be used interchangeably with petroleum derived fuels. These fuels are termed “drop-in” fuels and can be used in the pure ... -
Separation of noble gas mixtures of (Xe, Ar and Kr) using gas hydrate technology.
(2020)The separation and purification of xenon from xenon + argon + krypton mixtures is an important research area owing to the increasing industrial demand for the gas. While cryogenic distillation, membrane technology and ... -
Sustainable plant-derived coagulating agents in a heterogeneous platform for front-end water purification.
(2020)Chemical coagulants have been associated with having adverse economic, health and environmental impacts. Many rural communities do not have access to specialised coagulating agents and infrastructure for water treatment ... -
Application of the truncated perturbed chain-polar statistical associating fluid theory (tPC-PSAFT) to alcohol/alkane mixtures at high pressures.
(2020)Constitutive equations, such as equations of state (EoS) characterize mathematical relationships between state functions under set physical conditions and are imperative for the accurate design of chemical processes ... -
Low temperature optimization of copper recovery from e-waste.
(2021)The purpose of the report is to provide a detailed investigation on the recycling of copper from waste electronic Printed Circuit Boards (PCBs). The roles played by leaching agent, temperature, time, particle size, and ... -
Phase equilibrium studies and the blending/separation potential of alcohol, ketone and alkane mixtures for process design applications.
(2021)Abstract available in PDF. -
Effect of ageing on the physicochemical properties of fresh faeces.
(2021)Conventional onsite sanitation facilities, like pit latrines and urine diversion toilets, and innovative reinvented toilets with in-situ excreta treatment involve onsite storage of faecal matter for a certain period, where ... -
Degradation studies of carbamazepine and escherichia coli in wastewater using a non-thermal electrical discharge reactor.
(2021)Over the last 30 years, there has been increasing detection of emerging chemical pollutants and biological contaminants in the aquatic environment. As Wastewater Treatment Plants (WWTP) are considered the primary gateway ... -
Beneficiation of sawdust: chemical fractionation of lipophilic extractives.
(2019)Lipophilic extractives are generally known to be those compounds in wood that cause pitch problems in the pulp and paper industry. However, these compounds are advantageous to the biorefining industries as they contain a ... -
Co‐digestion of industrial and domestic wastewater.
(2020)This study is part of an extensive project studying the possibility of co-digestion of industrial and domestic wastewater at Amanzimtoti Wastewater Treatment Plant in Durban, South Africa. The focus of this study was to ...
