Water treatment

Water treatment methods include physical treatment and chemical treatment. The way of water treatment has been used by human beings for many years. Physical methods include the use of various filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude the impurities in the water. The more important of the adsorption methods is the adsorption with activated carbon. The barrier method is to pass the water through the filter materials, so that the larger impurities cannot pass through, so as to obtain cleaner water. In addition, the physical method also includes the precipitation method, which is to let the impurities with smaller specific gravity float on the water surface and fish out, or the impurities with larger specific gravity precipitate below, and then obtain. The chemical method is to use various chemicals to convert the impurities in the water into substances that are less harmful to human body, or to concentrate the impurities. The oldest chemical treatment method should be adding alum to the water. After the impurities in the water are collected, the volume becomes larger, and then the impurities can be removed by filtration.
