Volatile Organic Halide Removal

The only effective methods for removing volatile organic halides are activated carbon filtration and reverse osmosis. Reverse osmosis would be feasible only if other problems required its use. Studies show that the reduction efficiency for halogenated organics by activated carbon filters ranges from 76% for a faucet-mounted unit to 99% for several larger in-line units. However, one must keep in mind that the reduction is dependent on flow rate, contact time, and cleanliness of the unit as discussed in the section on these filters.
