Currently, world population is 7,62 billion people and thus the need for safe, clean water is imperious. World Health Organization/ UNICEF carried-out studies that almost 1,5 billion people are in danger because they do not have access to safe potable drinking water and nearly 3 billon people lack access to clean water. Studies suggest that an average human being use approximately 80-100 gallons of water per day. The well-known fact is that water is connected to nearly everything in the world, but its complexity should not narrow perceptive: water is a necessity for humans to have a decent life on a healthy planet. Since there is a major crisis regarding water, it emerges the need to develop technologies and minimize the risks of a human being. This review proposes the synthesis of silver nanoparticles and some potential applications in water treatment. Due to their attractive physiochemical properties in many applications, the main aim was to obtain silver nanoparticles through economic and efficient methods. Among other aspects of the silver nanoparticles involves the study of antibacterial effects with the benefits of using them in water purification. One of the challenging tendencies in the past decades was to use nanotechnology and its application to provide the most significant basic human right – drinking safe water free of bacteria and viruses. Through the benefits of nanotechnology were able to remove new contaminants by increasing the purification steps and reduce costs.
