Brewery effluent sludge characterization and dewatering to increase potential water recycling capabilities
In this study various coagulants and flocculants were tested for optimum removal of COD from brewery wastewater. The coagulants used were ferric chloride and an organic coagulant mixture obtained from the brewery company. ...
Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates
The effect of porosity of coal tailings on the mobilization and speciation of heavy metals is important for the implementation of management strategies. In this study, column leaching experiments were carried out to ...
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 ...
Bentonitc clay adsorption affinity for anionic and cationic dyes
The incidence of dye pollution in South Africa is quite alarming, requesting effective and affordable techniques to curb further degradation of the limited water resource. Adsorption is an attractive technique due to a ...
Selective adsorption of heavy and light metals by natural zeolites
Recent studies have shown that zeolite can be applied through an ion-exchange process to remove metals from solutions. In this paper the potential of two zeolites to perform as sorbents for treatment of multi-metal system ...
