Articles in Press, Accepted Manuscript, Available Online from 13 July 2019

http://dx.doi.org/10.22034/GJESM.2019.04.02

Abstract
  The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. ...  Read More

J. Samaniego; M.A.N. Tanchuling

Articles in Press, Accepted Manuscript, Available Online from 30 August 2019

http://dx.doi.org/10.22034/GJESM.2019.04.06

Abstract
  The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal ...  Read More

A. Cruz-Salomón; E. Ríos-Valdovinos; F. Pola-Albores; S. Lagunas-Rivera; R. Meza-Gordillo; V.M. Ruíz-Valdiviezo; K.C. Cruz-Salomón

Volume 5, Issue 1 , Winter 2019, , Pages 119-138

http://dx.doi.org/10.22034/gjesm.2019.01.10

Abstract
  The expanded granular sludge bed bioreactor appears today as a cheap, robust and more popular technology because it operates using a fluidized bed, which allows increasing in organic load and in cell retention times, generating higher treatment efficiencies (up to 95 %) and renewable energy (i.e., biogas, ...  Read More
