R. Mostafaloo; M. Asadi-Ghalhari; H. Izanloo; A. Zayadi

Volume 6, Issue 2 , Spring 2020, , Pages 191-202

http://dx.doi.org/10.22034/gjesm.2020.02.05

Abstract
  Ciprofloxacin antibiotic that is used to cure several kinds of bacterial infections have a high solubility capacity in water. The influent of ciprofloxacin to water resources in a low concentration affect the photosynthesis of plants, transforms the morphological structure of the algae, and then disrupts ...  Read More

2. Conventional steam activation for conversion of oil palm kernel shell biomass into activated carbon via biochar product

A.C. Affam

Volume 6, Issue 1 , Winter 2020, , Pages 15-30

http://dx.doi.org/10.22034/GJESM.2020.01.02

Abstract
  Conventional steam activation pyrolysis of waste materials such as oil palm kernel shell for production of biochar was investigated using central composite design. Conventional steam activation was carried out via an initial carbonization of oil palm kernel shell to obtain biochar and thereafter steam ...  Read More

3. Optimal conditions for the biological removal of ammonia from wastewater of a petrochemical plant using the response surface methodology

M. Samimi; M. Shahriari Moghadam

Volume 4, Issue 3 , Summer 2018, , Pages 315-324

http://dx.doi.org/10.22034/GJESM.2018.03.005

Abstract
  High concentrations of nitrogen compounds, such as ammonia observed in the petrochemical industry, are the major environmental pollutants. Therefore, effective and inexpensive methods are needed for its treatment. Biological treatment of various pollutants is a low cost and biocompatible replacement ...  Read More
