  • Are natural zeolites effective adsorbents in water treatment?
  • 21. Wang S, Peng Y. Natural zeolites as effective adsorbents in water and wastewater treatment. Chemical Engineering Journal. 2010; 156:11-24 22. Margeta K, Zabukovec Logar N, Šiljeg M, Farkaš A. Natural zeolites in water treatment—How effective is their use. In: Elshorbagy W, Rezaul Kabir Chowdhury RK, editors. Water Treatment.
  • Why are natural zeolites used in wastewater treatment?
  • In the past decades, utilisation of natural zeolites has been focussed on ammonium and heavy metal removal due to the nature of ion exchange and some review papers have been appeared , , . Apart from the presence of cations in water, anions and organic compounds are widely presented in wastewater.
  • How to remove zeolite water?
  • Zeolite water can be removed by heating to approximately 400 °C.The hydration of iron modified zeolite was 17 % higher than that of Na-modified zeolite and natural zeolite. 5.
  • What are modified natural zeolites used for?
  • Nowadays, modified natural zeolites are increasingly used also for biological treatment of water, precisely for surface binding of biological agents from water. Further research should be focused on the optimization of the surface modification procedures to raise their efficiency and to enhance the capability of regeneration.
