Water purification system by untreated source water to produce purified water suitable for human consumption. The system can remove substances include suspended solids, color, odor, bacteria, microbes, metal ions and chemical contaminants. Water purification process not only determines the quality of the water, but also affect water transport and marketing. Therefore, in practical application to retain a portion of fungicides in the treated water is used to eliminate bacterial contamination may be encountered in the process of circulation. Water treatment systems using modern energy efficient membrane separation systems, ozone and ultraviolet disinfection to produce healthy, safe drinking water. Our main water treatment equipment quartz sand filters, activated carbon filter, sodium ion exchanger, precision filter, reverse osmosis units, hollow fiber filters, ozone mixing tanks and storage tanks.
