Exploring Bioelectrochemical Systems for Removal and Recovery of Hexavalent Chromium or Nutrients
… resources in an energy-efficient manner. One of the potential applications of BES is to remove and recover nutrients simultaneously from nutrient-rich wastewater, such as digested manure from livestock. A four-chamber BES was developed and used in this study to explore the potential to remove …

Sorption of Boron and Chromium Onto Solids of Environmental Significance: Implications for Sampling and Removal in Water Treatment
… chemistry, analysis, treatment, and occurrence of boron and chromium are of high interest since they are under consideration for revised MCLs in potable water. As a starting point to guide regulatory decision-making, a comprehensive review of boron in relation to potable water was undertaken. …

Preparation and characterisation of poly (vinyl alcohol)/chitosan/silicon dioxide (PVA/CS/SiO2) beads for the chromium (VI) (Cr(VI) removal
Chromium pollution has become a global issue and many techniques have been developed for the removal of Chromium (VI) (Cr(VI)) from wastewater. In this study, blend polymer absorbent beads which was poly (vinyl alcohol)/chitosan/silicon dioxide (PVA/CS/SiO2) beads were prepared by dropwise method …

Evaluation of pollution potential and bioremediation of tannery-based chromium wastes in Sub-Saharan Africa: the case of dump sites in Beit Ore Tannery in South Africa and Dogbone Tannery in Kenya
The leather tanning technology is one of the oldest industry in humankind’s civilisation history. It converts raw hides and skins into non-putrescible products used in making various leather materials. Globally, Africa accounts for 4% of the world leather production and 3.3% of value addition in …
