  • Characterization of Netiyagama Soil (Sri Lanka) for the Fate of Fluoride in Groundwater 
    Heenkenda, K. Y.; Shabnam, M. F. A.; Jayawardhene, G. G. D. P.; Rukshagini, P.; Herath, A.C.; Weerasooriya, R. (Faculty of Technology Rajarata University of Sri Lanka, 2021-12)
    Inhabitants from the dry zone of Sri Lanka are vulnerable to serious health problems due to a lack of safe drinking water because of high fluoride and salinity. Major parameters that control the fluoride fixation are pH, ...
  • Comparison of Electrocoagulation and Electrodialysis Water Treatment Technologies for Dry Zone Groundwater – Sri Lanka 
    Halpegama, J. U.; Nanayakkara, K. G. N.; Binghui, T.; Herath, A.C.; Weerasooriya, R. (Faculty of Technology Rajarata University of Sri Lanka, 2021-12)
    Most of the drinking water sources in the dry zone are highly saline. Water desalination is achieved by reverse osmosis or nano filtration membrane methods. These methods are costly and the water is often over treated ...
  • Interaction between Graphite Oxide and Sand Granules: The Effect of Temperature 
    Bandara, P. M. C. J.; Kumarasinghe, A. R.; Balasooriya, N. W. B.; Bandara, A.; Weerasooriya, R. (Faculty of Technology Rajarata University of Sri Lanka, 2021-12)
    Graphite oxide (GO) coated sand composites were used to remove contaminants in water. We used GO coating on the sand by heat treatment without adding a binder. GO was synthesized by improved Hummer’s method. The GO was ...
