The conventional strategies for iron removal have been further divided into different techniques such as oxidation-precipitation-filtration process, zeolite softening or ion exchange, limestone bed filtration, filter media separation, supercritical fluid extraction, Vyredox technology, solid sorption separation/adsorption, wetland treatment ...
Zeolite membranes exhibit well-defined pore dimensions at a molecular level, and high adsorption property and so can separate, in a continuous way, liquid and gas species based on molecular sieving effect and adsorption selectivity [5]. Zeolites are crystalline inorganic materials with channels and cavities.
Here are some ways how zeolite for water filtration works: Zeolite has the ability to absorb a wide range of solvents or contaminants. By removing such contaminants, it helps soften the water. In the same way, it can absorb mineral like calcium (Ca) and magnesium (Mg) from water and soften them.
