Abstract

The full-scale experimental study on iron removal from groundwater by fiber filtering media has been made.The results showed that fiber filtering media had shorter 'mature period' of 14 d and higher efficacy of iron removal.Iron in the groundwater could be removed from 11.6 mg/L to 0.3 mg/L and below.Fe3+ concentration is an important factor which influences the iron removal effect.Reducing retention period after aeration and controlling aeration rate are needed to reduce Fe3+ concentration before filters.The mechanism and characteristics of iron removal by fiber filtering media are discussed.The wash steps and suitable washing rate of fiber filters are put forward.
