Water purification is the process of removing contaminants from water.[1] One reason is to make it safe for humans to consume.[1] Another is industrial use such as cleaning and cooling microchips during manufacturing.[2] According to a 2007 World Health Organization (WHO) report, 1.1 billion people do not have access to clean drinking water.[3];)
