[0002] Water treatment methods include physical treatment and chemical treatment. Humans have been treating water for many years. Physical methods include using filter materials with different pore sizes to remove impurities from the water through adsorption or barrier methods. The most important adsorption method is adsorption with activated carbon. The barrier method is to pass water through the filter material so that larger impurities cannot pass through, thereby obtaining cleaner water. In addition, physical methods also include sedimentation, which is to allow impurities with smaller specific gravity to float on the water surface and be fished out, or to allow impurities with larger specific gravity to settle at the bottom and then be obtained; chemical methods use various chemicals to convert impurities in the water into substances that are less harmful to the human body, or to concentrate the impurities. The oldest chemical treatment method should be to add alum to the water. After the impurities in the water gather and become larger in size, they can be removed by filtration;
