Abstract
  Olive milling wastewater is a major problem facing the Mediterranean countries producing olive oil like Egypt. In the present study, olive milling wastewater rich with organic phenolic compounds, macro and micro nutrients was used as growing media for cyanobacteria. The cyanobacteria were grown on wastewater ...  Read More

Sh.F. Abd El-Kader; G.A. El-Chaghaby; G.M. Khalafalla; R.I. Refae; H.M. Elshishtawy

Volume 5, Issue 1 , January 2019, , Pages 61-70

https://doi.org/10.22034/gjesm.2019.01.05

Abstract
  Congo red is a synthetic azo-dye dye with many industrial applications. The effluents containing azo dyes are causing several environmental hazards and thus should be treated prior to their discharge. The present work investigates the possible use of a novel microbial consortium from sheep compost for ...  Read More

N.T. Abdel-Ghani; G.A. El-Chaghaby; F.S. Helal

Volume 2, Issue 3 , September 2016, , Pages 209-222

https://doi.org/10.7508/gjesm.2016.03.001

Abstract
  In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric ...  Read More

Equilibrium and kinetic study for the adsorption of p-nitrophenol from wastewater using olive cake based activated carbon

N.T. Abdel-Ghani; E.S.A. Rawash; G.A. El-Chaghaby

Volume 2, Issue 1 , January 2016, , Pages 11-18

https://doi.org/10.7508/gjesm.2016.01.002

Abstract
  The present work was carried out to evaluate the removal of p-nitrophenol by adsorption onto olive cake based activated carbon having a BET surface area of 672 m²/g. The batch adsorption experimental results indicated that the equilibrium time for nitrophenol adsorption by olive cake-based activated ...  Read More
