Methanogenic digestion of lignocellulose residues under conditions of high-rate acidogenic fermentation
A semicontinuous module reactor was operated under methanophilic conditions to effect rapid solid anaerobic digestion of lignocellulose substances for waste utilization and stabilization. This was achieved by recovering ...
Elution of ion exchange resins by use of ultrasonication
The feasibility of using ultrasound to enhance the elution of three ion exchange resins was investigated. A laboratory-scale elution column immersed in an ultrasonic bath was used to investigate three elution systems. ...
Recovery of chromite fines from wastewater streams by column flotation
In the Western Chrome Mine in South Africa, the process water stream contains approximately 3% chromite fines (<100 μm), which report to the tailings dam. This results in resource loss and water contamination. Consequently, ...
Adsorption of heavy metals by biomaterials derived from the marine alga Ecklonia maxima
The adsorption of heavy metals onto biomaterial derived from the marine alga Ecklonia maxima was investigated via batch experiments. The adsorption equilibria of Cu, Pb and Cd could be represented by Langmuir isotherms and ...
