An Isomer-Specific Correlation between Dioxin Isomer Concentration in Wastewater and Removal Efficiency of Chemical Clarification

An Isomer-Specific Correlation between Dioxin Isomer Concentration in Wastewater and Removal Efficiency of Chemical Clarification

Coagulation-precipitation treatment using ferric chloride was carried out in wastewater taken from a solid waste incinerator wet scrubbing system. The treated wastewater was fractionated with 1 μm and 0.1μm filter, and the dioxin concentration in each fraction was determinde. The isomer profiles ind...
