The impact of zeta potential changes on Ceratium hirundinella cell removal and the ability of cells to restore its natural surface charge during drinking water purification
Ewerts, H.; Barnard, S.; Swanepoel, A. (RSC, 2017)Unit processes of a conventional water purification facility are designed to remove suspended material from source water (both inorganic and organic impurities). Organic substances in source water include phytoplankton ... -
Laboratory-scale simulations with hydrated lime and organic polymer to evaluate the effect of pre-chlorination on motile Ceratium hirundinella cells during conventional water treatment
Ewerts, H.; Barnard, S.; Swanepoel, A. (Water Research Commission, 2016)Algal genera such as Carteria, Chlamydomonas, Chlorogonium, Cryptomonas, Ceratium, Peridinium and Euglena are motile and may disrupt unit processes and cause water treatment problems. Algal species belonging to these ... -
Physical and chemical impacts of conventional unit processes and coagulants on the dinoflagellate, Ceratium hirundinella
Ewerts, H.; Janse van Vuuren, S.; Tiedt, L.; Swanepoel, A. (IWA Publishing, 2016)The freshwater dinoflagellate, Ceratium hirundinella (C. hirundinella) with its complex morphology and robust thecal plate cell covering, is responsible for extensive problems during drinking water production. To have a ... -
Strategies of coagulant optimisation to improve the removal of turbidity and Ceratium hirundinella cells during conventional drinking water purification
Ewerts, H.; Barnard, S.; Swanepoel, A.; Du Preez, H.H.; Janse van Vuuren, S. (IWA Publishing, 2014)The dinoflagellate, Ceratium hirundinella (C. hirundinella) cells are known to cause many problems when source water due for purification contains relatively high concentrations. The objective of this study was to investigate ...
