Studies on the adsorption of metal ions in batch mode using modified chitosan beads have been reported by several authors in the literature. Consequently, packed bed column studies are performed for large-scale operations to generate data directly applicable to real wastewater treatment. For packed column adsorption, how to predict the breakthrough...
The exceptional properties of chitosan and its effective technique of adsorbing contaminants even to near-zero concentrations are the primary reasons for special attention. The adsorption studies analyzed various elements, including pH, concentration, contact time, and adsorbent dose. The study used these factors as input data, with the output data...
Heavy metal contamination in water presents significant environmental and health challenges, making effective removal methods essential. This study investigated amino-functionalized grafted cross-linked chitosan beads (Chis_CL_Gr) as an adsorbent for removing Pb²⁺ and Cu²⁺ ions from synthetic wastewater. The chitosan beads were prepared and modifie...
Plastic pollution, a global crisis with severe environmental and economic ramifications, mainly affects African countries, which are major contributors to oceanic plastic waste. The Southern African Development Community (SADC) region is grappling with urgent waste management and recycling challenges exacerbated by the escalating demand for plastic...
This study examined the heavy metal (HM) levels in five subsoil samples (S1-S5) collected from an abandoned quarry mine (AQM) and a baseline sample (S6) taken from a nearby school to provide a comparison point in Nseleni, KwaZulu-Natal province. The pH and EC values for S1-S5 ranged from 3.3-5.0, and 1100-1400 µS/cm, respectively. The maximum HM co...
Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants commonly found in the petroleum and mining industries, which can have detrimental effects on the environment. Due to their toxicity, PAHs in the environment can lead to adverse clinical outcomes for humans and livestock. Consequently, developing effective processes for degrading PAHs in...
Mining supplies key resources necessary for technological advancement to ameliorate challenges imposed by the increase in the human population worldwide. One of the legacies of mining resources is the formation and discharge of acid mine drainage (AMD) during and even after active mining. It is a major environmental concern because it enhances the...
South Africa is faced with challenges related to potable water quality, which has periodically deteriorated, coupled with inconsistent supply of tap water to households. On the other hand, South Africa is an important mining region, and nearly every province has remnants of active and closed metalliferous mining sites. Metalliferous mines produce a...
South Africa is an important mining region, and nearly every province has remnants of active and closed metalliferous mining sites. Metalliferous mines produce a large quantity of metalliferous solid waste (MSW) because the ore is minutely portioned in comparison to the mined material. In the metalliferous industry, production of Cu, Pb, and Zn cul...
In this study, the hydrochemical characteristic changes of open-pit groundwater (OPGW) near a closed metalliferous mine proposed for drinking and irrigation usage were investigated. Water samples from an OPGW in O’Kiep were collected in April (dry season) and August (wet season), 2017. Data analysis methods, such as the coefficient of variation, co...
Water insecurity is a growing concern globally and the role of groundwater and aquifers in buffering the effects of climate variability and change is increasingly acknowledged due to extended periods of drought in arid regions. Water security can only be fully realised with a more robust understanding of groundwater as a water resource, especially...
The metagenomic data presented herein contains the bacterial community profile of a drinking water supply system (DWSS) supplying O'Kiep, Namaqualand, South Africa. Representative samples from the source (Orange River) to the point of use (O'Kiep), through a 150km DWSS used for drinking water distribution were analysed for bacterial content. PCR am...

O’kiep, a small town located in the arid to semi-arid
Namaqualand region of South Africa is dependent on the Lower
Orange River for its water needs, i.e. for domestic and agricultural
use. The protection of groundwater resources in this region is
important due to water shortages with no peripheral rivers. The town
is characterised by an environment...
Mining activities cause environmental pollution
problems by contaminating nearby areas with heavy metals (HM) such
as Cu, Fe, Zn and Al from overburden and leachates. HM can leach
into groundwater, be transferred into rivers, and streams by surface
run-off, in a form of dissolved species or as a part of suspended solids,
culminating in their accumu...
