| Abstract |
The production and removal of six volatile halogenated organic compounds during treatment of tertiary clarified and filtered wastewater by breakpoint chlorination and activated carbon was examined in a continuous flow pilot plant. Short contact time breakpoint chlorination of filter effluent increased chloroform and bromodichloromethane concentrations by 50 micrograms/liter and 10 micrograms/liter, respectively. Treatment by carbon prior to chlorination reduced the formation of chloroform by a factor of four, but was less effective in reducing the amount of bromoform produced. A 20-minute empty bed contact time activated carbon adsorber was much more efficient for chloroform removal than a 10-min adsorber, probably because of competitive effects of more strongly adsorbed organics. The removal of chloroform by the second stage carbon contactors conformed to an equilibrium expression of the Freundlich type. |
