Water purification
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] Unclean water is not only harmful to your health but equally damaging for the plumbing, home appliances, kitchen, washroom, and everything.[3] According to a 2007 World Health Organization (WHO) report, 1.1 billion people do not have access clean drinking water.[4]
