Leachate
Increasing of leachate quality using an integrated aerobic membrane bioreactor
The aim of this study was the increasing of leachate quality using integrated membrane bioreactor (MBR). The reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (COD). The analysis of COD, biochemical oxygen demand (BOD5), total suspended solids (TSS), and total dissolved solids (TDS) were performed in feed and filtrate, whenever the system reached steady state twice a week for 6 months.
Assessing landfill leachate heavy metal effect on the surface water quality: A case of Gheshlagh River, Sanandaj City, Iran
Pollution resulted from the leachate of the Sanandaj City landfill into Gheshlagh River is an important environmental and health issue, which has endangered the river. Having a population of more than 400,000 and four municipality districts, the solid waste generation rate is approximately more than 300 tons/day in Sanandaj City.
The Effect of H2O2 Interference in Chemical Oxygen Demand Removal During Advanced Oxidation Processes
Hydrogen peroxide (H2O2) is one of the most oxidants in AOPs. By H2O2 dissociation, hydroxyl radical with a standard oxidation potential of 2.7 is produced. It is reported H2O¬ residual in AOPs has been led to interference in chemical oxygen demand (COD) test and it is able to hinder biological treatment of waste water.
