Abstract

The removal of iron from Alaskan groundwaters by a foam fractionation technique has been shown to very effective. Finished waters with less than 0.2 mg/l iron have been produced from raw waters containing in excess of 25 mg/l. Ethylhexadecyldimethylammonium bromide was used as the principal foaming agent. Low temperature oxidation of the ferrous iron tended to interfere with the removal rates, but high temperature oxidation followed by low temperature fractionation did not exhibit the same adverse influence. All experiments were performed in four-liter laboratory batch columns. For the Alaskan environment batch processing is thought to have advantages over continuous processes because of the need for uncomplicated equipment.
