During the groundwater pumping process, dissolved Fe 2+ is oxidized into Fe 3+ and
produce rust-coloured iron mineral. Adsorption kinetic models are used to evaluate the …

Adsorption using low cost of media plays more attention to this current research. Previous
literature found that high quality of limestone was effective in removing heavy metals in …

When the manganese is under the acceptable limit, then the removal of Fe (II) ion, the
common metallic compound contained in groundwater, is one of the most important stages …

Iron is an essential trace element, but at high doses, this element may pose a health risk.
Wastewater from iron ore mining, steel production, and metal processing, among other …

One of the factors influencing freshwater contamination is caused by pollutants and organic
matter from anthropogenic activities. The appearance of ferrous and manganese metal ions …

Understanding the characteristic of adsorbent media is important to assess their
compositions, particle size, morphology and the functional group. In this study, limestone …

After the water adsorption process, the content of Fe (II) ion meets drinking water standard
below 0.3 ppm. Based on the kinetic indicator of the absorption coefficient of correlation (R …

The presence of iron in water is one of the essential reasons of water pollution. In the
present study, we use modified hydroxyapatite as adsorbent material to remove Fe+ 3 from …

Several techniques are used for iron and manganese removal from groundwater. Among
these treatments, adsorption has been proven to be a very effective in metal removal for …

Iron is a chemical element that is found in groundwater that can be suspended in the form of
ferrous cations. Iron presence that exceeds the threshold can cause detrimental effects such …
