Reduction of salinity of water using acrylamide-based polyampholyte
Polyampholytes are charged macromolecules, which carry both acidic and basic groups. These groups dissociate, leaving ions on chains and counter ions in solution, under appropriate conditions, ...
Prediction of dissolution of copper from a chalcopyrite carbonatite ore of South Africa
Chalcopyrite accounts for 70% of all copper bearing minerals and therefore has been studied closely to understand the dissolution kinetics in hope of overcoming the passivation film and increasing the extraction rates ...
Adsorption of metal ions from fine coal tailings dump waste water using bio-char
Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee ...
Biological reduction of COD and sulphate by SRB in anaerobic moving bed biofilm reactor under high metal loading conditions
The performance of an anaerobic moving bed biofilm reactor (MBBR) containing AnoxKaldnesTM K5 model for the treatment of raw acid mine drainage (AMD) was investigated for the reduction of sulphate and chemical oxygen ...
