With the increased awareness of environmental practices, the number of complaints regarding unpleasant odours from industrial and municipal facilities has increased considerably over the last ten years, primarily as a result of the population growth and the encroachment of residential developments onto land surrounding industrial facilities. Wastewater treatment, solid waste management, and various industrial practices […]
Carbonation of raw red mud produced by aluminium refineries and a chemically and physically neutralized red mud (Bauxsol™) has been carried out to study the capacity of these wastes to capture carbon dioxide. After only 5 min of carbonation of raw red mud, total alkalinity dropped 85%. Hydroxide alkalinity was almost totally consumed, carbonate alkalinity […]
The effects of Bauxsol, an abundant industrial by-product, on the immobilisation of soluble acid and a range of potentially environmentally toxic metals in artificial and natural acid sulfate soils were investigated. The acid neutralising capacity of Bauxsol™ increased with decreasing pH, which is probably provided not only by basic metal hydroxides, carbonates, and hydroxycarbonates but […]
The reagents used in Virotec technologies have several remarkable characteristics that make them ideal for environmental remediation for soils and water. Virotec’s Reagents have an excellent trace metal and metalloid binding capacity and, equally importantly, elements that are bound when the material is used to treat contaminated water or soil are held very tightly and […]
