Zeolite earth in crude form many types of crystals. Only micro crystalline alkali earth metal, Aluminiu Silicates are known as Zeolite. This is because the absorption of gases takes place through the surface area. Therefore only micro crystalline form of zeolite shall give desired results. Furthermore, zeolites having tetrahydra structure with maximum Calcium form are useful in Aquaculture. This is because Calcium ion is easily exchangeable with Ammonium ion. DeoMed is processed so that only refined micro crystalline forms high in Calcium and having tetrahydra structures are seived out to attain a very high Cation Exchange Capacity (CEC) of 400-420 m.e/100gm.
