Removal of iron from groundwater by ash: A systematic study of a traditional method

Removal of iron, arsenic and coliform bacteria from water by novel constructed soil filter system

“…Iron is seldom found at concentrations greater than 10 milligrams per liter (mg l −1 ) or 10 parts per million. However, as little as 0.3 mg l −1 can cause water to turn a reddish brown color (Das et al, 2007). Thus, the removal of iron is necessary.…”

“…This sediment is the oxidized or ferric form of iron that will not dissolve in water. There are several methods for removal of iron from drinking water like ion exchange and water softening (Vaaramaa and Lehto, 2003), activated carbon and other filtration materials (Munter et al, 2005), bioremediation (Berbenni et al, 2000), oxidation by aeration, chlorination, ozonation followed by filtration (Ellis et al, 2000), by ash (Das et al, 2007), by aerated granular filter (Cho, 2005) and by adsorption (Tahir and Rauf, 2004).…”

Thermodynamics Approach in the Adsorption of Heavy Metals

“…In practice form recent studies, the natural zeolite [19], activated carbon [36], olive cake [21], quartz and bentonite [20] and jojoba seeds [37] are used as an adsorbent for the adsorption of mainly trivalent iron ions in aqueous solution. The Motivation for the removal and sorption Fe 3+ ions is that iron ions causes serious problems in the aqueous streams especially at high levels concentration [38 -39].…”

Removal of Fe3+ from Aqueous Solution by Natural Apatite

“…Iron ions are attracting wide research attention since they are found in many manufacturing industries such as coatings, car, aeronautic and steel industries [9]. Many absorbents have been reported for removal of iron ions (Fe 2+ or Fe 3+ ), such as bacterias [9,10], chitin [11], palm fruit bunch and maize cob [12], Bengal gram husk [13], tur dal husk [14], eggshells [15], ash [16], sawdust [17], activated carbon [18], natural zeolite [19], bentonite and quartz [20], and apatite [21][22][23].…”
