Brewery effluent sludge characterization and dewatering to increase potential water recycling capabilities
(EARET, 2018)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. ... -
Coagulation/flocculation potential of polyaluminium chloride and bentonite clay tested in the removal of methyl red and crystal violet
(Springer, 2017)This study investigated the influence of the physico-chemical properties of methyl red (MR) and crystal violet (CV) on their removal by bentonite clay and polyaluminium chloride (PACl). Different dosages of bentonite clay, ... -
Flocculant types and operating conditions influencing particles settling rates in feed water used at a coal power plant
(Desalination Publications, 2019)South Africa is a semi-arid country with an average rainfall less than half of the average rainfall worldwide. From the country limited water resource, 2%–3% of the water is used in energy generation. Thus the water ... -
Hydrogel-based bioflocculants for the removal of organic pollutants from biodiesel wastewater
(Springer, 2017)Hydrogel based bioflocculants namely Gelatin and acrylic acid-co-acrylamide [GL-cl-P(AA-co-AAM)] and hybrid hydrogel composite with good adsorption potential, were synthesized in this study for the treatment of biodiesel ... -
Investigation of effective chemical flocculation conditions for the treatment of reverse osmosis reject water from coal power plant: a case study
(Desalination Publications, 2020)Power generation processes generate wastewater that is rich in scale-forming agents and which, therefore, requires suitable pre-treatment prior to further treatment with an RO system. In this study, Rheofloc5023 was used ... -
Pretreatment of coal power plant ro retentate using AR Floc 100
(EARET, 2018)The water purification process at Eskom includes a reverse osmosis (RO) treatment plant. There are several limitations to this process depending on the water characteristics. The most common problems limiting the success ... -
Removal of COD from biodiesel wastewater using a hydrophobic polymer
(EARET, 2018)Biodiesel production is increasing internationally as an alternative fuel. This is due to the rapid depletion of non-renewable energy sources. Pure biodiesel product can be obtained by washing the product with hot water. ... -
Synthesized af-PFCl and GG-gP (AN)/TEOS hydrogel composite used in hybridized technique applied for AMD treatment
(Elsevier, 2018)In the present study af-PFCl, GL-g-P(AN) hydrogel and GL-g-P(AN)/TEOS hydrogel composite were synthesized. The hydrogels were characterized using the fourier transformed infra-red (FTIR) and the scanning electron microscope ...
