ZEOSORB® has been introduced to the process purification of drinking water and wastewater due to its large specific surface area and the selective adsorption of substances, such as ammonia, dissolved organic matter and many other cations. Moreover, ZEOSORB® has advantageous hydraulic properties, that is the filtration capacity of large quantities of water. Compared with other adsorbents, ZEOSORB® is more stable, has better filter features, accessible and relatively cheaper.
Based on numerous studies, it can be concluded that ZEOSORB® has great potential as an effective adsorbent in numerous processes of purification of drinking water and wastewater, such as water softening, removal of ammonia (from municipal wastewater, wastewater from livestock farms, barn manure, water from ponds and swimming pools, removal of nitrogen, removal of dissolved organic matter and color, removal of heavy metals (from natural water, acid mine water, industrial wastewater), removal of radioactive substances from wastewater, desalination seawater and many others. ZEOSORB® performs as a polyfunctional sorbent in the wastewater treatment process and it binds several harmful components. However, it does not possess the ability of anions adsorption due to the negative charge of its aluminosilicate network. Superficial modification of ZEOSORB®, by means of organic modifiers, allows partial neutralization of negative charge of the external surface of ZEOSORB® media.
Physical filtration barriers for accumulation or collection of microorganisms in the water that endanger human health have been in focus during the last several years. ZEOSORB® will be an ideal collector of pathogens such as giardia, cryptosporidium and other bacteria and their spores. Most of these organisms and their spores are in the size range of 0.5 – 10 micrometers (microns). In contrast, the water-permeable pores in ZEOSORB® are mostly smaller than .05 microns; therefore the ZEOSORB® fragment or granule can “surface collect” a high percentage of these microorganisms while the water passes through the ZEOSORB® fragment. All drinking water standards for microorganism pathogens and turbidity can be most easily met using a natural, relatively low-cost material, such as ZEOSORB® rather than “sand” which is chiefly quartz grains.
