H.D. Tran; H.M.T. Vi; H.T.T. Dang; R.M. Narbaitz

Volume 5, Issue 3 , Summer 2019, , Pages 331-344

http://dx.doi.org/10.22034/GJESM.2019.03.06

Abstract
  Constructed wetlands have not been commonly used in Vietnam due to the lack of information in the selection of proper types of constructed wetlands, type of reeds, design parameters and performance efficiency, in tropical climates. This paper focuses on Canna generalis, which is a common reed and easy ...  Read More

4. Polluting potential of post-Fenton products in landfill leachate treatment

M.R. Sabour; A. Amiri

Volume 3, Issue 2 , Spring 2017, , Pages 177-186

http://dx.doi.org/10.22034/gjesm.2017.03.02.006

Abstract
  Fenton process, as one of the most conventional advanced oxidation processes, is widely used in the treatment of specific wastewaters, especially landfill leachate. In current study, the main target was to evaluate some neglected aspects of Fenton process in operational applications. Thus, three novel ...  Read More
