  • Fate of Arsenic during Biological Treatment of High Strength Wastewater–Case Study

    The paper presents the results of treatability study on highly contaminated wastewater with phenols (300 mg/l), thiocyanate (210 mg/l), ammonia (800 mg/l) and arsenic up to 11 mg/l. The study was conducted in two sequencing batch reactors (SBRs) using biomass from coke plant. After two months of acclimatization the biomass was able to remove ammonia to below 1 mg/l and phenols and thiocynate ...

  • Comparative Risk Assessment

    ' Comparative risk assessment provides a systematic way to compare environmental problems that pose different types and degrees of health risk. It combines information on the inherent hazards of pollutants, exposure levels and population characteristics to predict the resulting health effects.
