1. Groundwater Denitrification by Using MBBR With KMT Packing

A. Hemmati; M. Raeisi; M. borghei

Volume 17, Issue 4 , Autumn 2020, , Pages 60-68


  Many communities in the world use groundwater as a source of potable water. The high nitrate concentration is a serious problem in groundwater usage. This study utilizes a biological denitrification method to investigate a moving bed biofilm reactor (MBBR) for the case of Tehran's groundwater. One pilot-scale ...  Read More

2. CO2 biofixation by Dunaliella Salina in batch and semi-continuous cultivations, using hydrophobic and hydrophilic poly ethylene (PE) hollow fiber membrane photobioreactors

V. Mortezaeikia; R. Yegani; M.A. Hejazi; S. Chegini

Volume 13, Issue 1 , Winter 2016, , Pages 47-59

  In this work, performance of hollow fiber membrane photobioreactor (HFMPB) on the growth of Dunaliella Salina (G26) at various aeration rates (0.1 and 0.2 VVm) and medium re-circulation flow rates (500 and 1000 mL/h) were studied. Cultivation was carried out at both batch and semi-continuous modes in ...  Read More
