Introduce Zn on Natural Zeolites and Investigation of Antibacterial Activity

Microorganisms are part of the organic matter in the wastewater. These organic materials can affect human health and are commonly found in wastewater because they are present in fecal material. The removal or inactivation of pathogenic microorganisms is the last step in the treatment of wastewater. Some chemical and physical agents, such as chlorine, ultraviolet light, reverse osmosis, and silver catalyst are well developed [1–3]. The bactericide activity of Zinc ions has been known for a long time. Zinc is an essential mineral perceived by the public today as being of "exceptional biologic and public health importance", especially regarding prenatal and postnatal development [4]. Zinc deficiency affects about two billion people in the developing world and is associated with many diseases. In the last few years, several investigations were carried out using synthetic and natural zeolites that combined with silver ions to obtain disinfection agents for the treatment by microbiologically polluted water.
