The optimum health of people can be assured and maintained by giving them access to clean drinking water. Contaminated water can be the vector for a lot of waterborne diseases like diarrhea, cholera, and dysentery. Fortunately, there are several ways to ensure that your water source is free from any impurities.
First, there are chemical means. There are several chemical substances that help clean water of any bacteria, however, they can render the water undrinkable, which then makes them applicable only for purposes like pool disinfection. Some examples are chlorine, bromine, iodine, and hydrogen peroxide. Chlorine is an especially harsh option as it only cleans bacteriological contamination and is regarded as a carcinogen, cholesterol increaser, and raises one’s risk for heart disease. Ion exchange is a safer option that uses glauconite, which turns calcium or magnesium into salt; it does result in salty water, but desalination usually follows the process.
Second, filtration systems are a more thorough way of removing impurities from water. Chemical, physical, and biological contaminants can be cleaned from the water using a filtering material. These can range from porous stone to cloth membranes. One of the more popular and effective systems combines having a filter and a physical process—this is the reverse osmosis filtration system. Basically, it functions by separating clean water from the contaminated water with the use of a special membrane.
