Removal of iron for safe drinking water

Universal access to safe drinking water is a challenge to the scientific community to which the responsibility is incumbent on developing appropriate technologies. Safe drinking water must be globally available to all communities worldwide. It can be roughly considered that water infrastructure is well developed in urban areas as opposed to rural areas where the infrastructure is either poorly developed or non-existent. Accordingly, the population to be urgently deserved with safe drinking water is the rural one. In this review we are trying to summarize all methods reported in the literature for the removal of iron from groundwater for water purification.

► Iron removal is among the problematic issues for making potable water. ► Its main issues involve taste, visual effects, and clogging ► Iron in the form of their hydroxide creates blockage in the pipe. ► Several removal methods summarized in here. ► Few methods are electro-coagulation: oxidation; ion-exchange; ultra-filtration, etc.
