Denitrification of high strength landfill leachate using garden refuse compost and pine bark.
(2009)Landfill leachate, a toxic by-product formed through the decomposition of organic matter, is harmful to the environment and human health. After nitrification, the concentration of nitrate in discharged leachate may still ... -
Denitrification of high strength nitrified landfill leachate using raw and lightly composted commercial garden refuse (CGR) as carbon sources.
(2011)Waste is commonly disposed in landfills, this result in the formation of leachate which needs to be treated to acceptable standards before being discharged to the environment. High concentrations of pollutants, particularly ... -
Denitrification of leachate using domestic waste at different levels of stability : simulations in batch test.
(2011)Disposing of waste on land has been a method practiced by many countries because it is relatively inexpensive. This has led to the fast increase of landfilling option which is also due to increase of waste generation, ... -
Development of ‘green’ rigid pavements incorporating recyclable rubber and paper mill products.
(2019)Natural aggregate resources used as conventional fillers in concrete production are constantly diminishing. Several studies have suggested that there will be a lot of pollution in the degradation of waste rubber products. ... -
The development of a latent heat thermal energy storage system using a phase change material for solar energy application.
(2010)This investigation forms part of an attempt to provide an alternative to conventional power generation technologies that use fossil fuels which have impact on global warming. The field of this investigation covers the ... -
Development of a mathematical model considering nutrients kinetics for assessing uMgeni river water quality.
(2018)Surface water is an essential component of the natural environment which needs to be sheltered from all sources of contamination because human and aquatic animals depend on it for their survival. However, the discharge of ... -
Development of a sustainable evolutionary-inspired artificial intelligent system for municipal water demand modelling.
(2020)This study presents the development of a differential evolution (DE)-inspired artificial neural network (ANN) that incorporates climate and socioeconomic information for a more accurate and reliable water ... -
Development of sounding equipment for the assessment of the time- settlement characteristics of recent alluvial deposits when subjected to embankment loads.
(1992)The whole of this thesis is my work unless specifically indicated to the contrary in the text, and has not been submitted in part or in whole to any other University. Some thirty years ago the author operated a deep ... -
Development of sounding equipment for the assessment of the time- settlement characteristics of recent alluvial deposits when subjected to embankment loads.
(1992)Many embankments on the soft, highly variable, recent alluvial deposits along the South African coast have suffered large settlements necessitating ongoing costly repairs. Due to the soft variable soils, borehole sampling ... -
An economic comparison of the waste management schemes employed in Cape Town and Johannesburg.
(2006)The disposal of waste into landfill sites is currently the most commonly employed method of dealing with waste in South Africa as well as internationally. However the global trend towards operating waste management systems ... -
Effective HIV and AIDS management : a South African construction sector model.
(2013)Abstract available on PDF file. -
The efficacy of using the microalgae chlorella sp. for the treatment of hazardous landfill leachate.
(2015)Abstract available in PDF file. -
Environmental impacts of the construction phase of an intensive development project on a coastal forest wetland : case study : Seaward Estates, Ballito.
(2011-01-14)Storm water runoff is a leading cause of degradation in the water quality of receiving water bodies. Although legislation requires that Environmental Impact Assessments (EIA) are performed and Environmental Management ... -
Environmental management strategy : Krantzkloof Nature Reserve, a case study.
(2006)KZN Nature Conservation Services budgetary cuts for the KrantzkloofNature Reserve (KNR) has led to economic shortfalls in important areas like facilities maintenance and invader plant control. The study has found that the ... -
Environmental study of the rehabilitation of the Monze-Zimba Road in Zambia.
(2001)It is very unfortunate that despite laws that require adequate incorporation and integration of environmental concerns at all phases of the economic developmental projects in Zambia, the research findings of this ... -
Estimating pedestrian accident risk using conflict techniques and digital imaging.
(2003)Accidents are a complex process involving many contributory factors. The understanding of the accident process has often been sought by the use of accident data. Although accident data provide a direct relationship to ... -
Evaluation of PCI reverse osmosis membrane on landfill leachate.
(2010-10-20)The specific objective of this study was to evaluate a PCI reverse osmosis membrane for -
Experimental cadmium contamination of the echinoid Stomopneustes variolaris (Echinodermata: Echinoidea) : influence of dosage and distribution of the metal in the organism.
(2002)Cd levels were measured in three different body compartments of the echinoid Stomopneustes variolaris after exposure to concentrations of 5 ug 1l, 20 ug 1l and 50 ug 1l Cd for a period of two weeks. The body compartments ... -
Effect of coral reefs on wave attenuation and erosion: Mnemba Island, Zanzibar.
(2017)Global warming and sea level rise are some of the greatest threats humanity faces today with low-lying coral reef islands most vulnerable to these threats and their repercussions. This study focuses on the mechanisms that ...
