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. ...
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. ...
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 ...
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 ...
