D. Pham Van; M.G. Hoang; S.T. Pham Phu; T. Fujiwara

Volume 4, Issue 4 , Autumn 2018, , Pages 401-412

http://dx.doi.org/10.22034/gjesm.2018.04.002

Abstract
  Kinetic models which can express the behaviors of hydrolysis and biogas generation more precisely than the conventional models were developed. The developed models were evaluated based on the experimental data of six batch reactors. Anaerobic digestion test was co-digestion of food and vegetable waste ...  Read More

4. A new kinetic model for biogas production from co-digestion by batch mode

D. Pham Van; M.G. Hoang; S.T. Pham Phu; T. Fujiwara

Volume 4, Issue 3 , Summer 2018, , Pages 251-262

http://dx.doi.org/10.22034/GJESM.2018.03.001

Abstract
  Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. ...  Read More

J. Aravind; P. Kanmani; G. Sudha; R. Balan

Volume 2, Issue 1 , Winter 2016, , Pages 61-68

http://dx.doi.org/10.7508/gjesm.2016.01.007

Abstract
  The current investigation presents the role of gooseberry (Phyllanthus acidus) seeds as an effective biosorbent for remediating chromium (VI)), a toxic heavy metal pollutant commonly found in effluents from tanneries and relevant industries. Biosorption was affected by pH, temperature and initial metal ...  Read More
