This is a conceptual framework introducing information about water filtration. This conceptual framework introduces two main factors about water filtration. Because the concentration of some elements in drinking water could produce biochemical toxicities in the human body and water faucets and pipes are rusted and dirty, plus the contaminated water, poor cleanliness, and the quality of the tap water require the usage of water filtration. Apart from that, the usage of water filtration can provide purified or cleaned water and guarantee the safety of users' health. Moreover, water filtration is economical, practical, and has a likelihood to save money over time. You can find this template on EdrawMax and create a conceptual framework easily.
