Recent studies have shown that zeolite can be applied through an ion-exchange process to remove metals from solutions. In this paper the potential of two zeolites to perform as sorbents for treatment of multi-metal system ...

The incidence of dye pollution in South Africa is quite alarming, requesting effective and affordable techniques to curb further degradation of the limited water resource. Adsorption is an attractive technique due to a ...

A possible new process for the partial desalination of seawater is to use bentonite clay or attapulgite as an adsorbent. The ion exchange property of these clays, which is a result of the characteristic t-o-t layer ...

There have been increasing concerns in developing countries over the competition between food and energy resulting from the production of bioethanol from edible biomass. Second generation lignocellulose feedstock is an ...

With the global fossil fuel supplies dwindling and the alarming increase of carbon dioxide in the atmosphere, the need for alternative, clean energies, from carbon neutral sources is pressing. This impetus advanced research ...

The degree of diesel blending is likely to influence its toxicity as well as the susceptibility and speed of biodegradation. It is therefore imperative to identify strains that can degrade diesel blend in record time, such ...

Power generation processes generate wastewater that is rich in scale-forming agents and which, therefore, requires suitable pre-treatment prior to further treatment with an RO system. In this study, Rheofloc5023 was used ...

Coal processing in the refinery industry often lead to the formation of coal tar containing polycyclic aromatic hydrocarbons which are likely to affect human and animal health when released in surface and ground waters. ...

Fresh water pollution by dyes from various industries is raising a lot of concern lately. Despite their well-known toxicity to humans, azo dyes make up over half of the used dye population. Rhodamines are also a well-used ...

— Due to increasing populations and an ever-changing climate, limited water resources are South Africa’s burden. Clean water is important for all living organisms’ health and environmental sustainability. To achieve ...
