In the water purification process, the first line of defense is crucial. The PP cotton filter effectively removes large particles such as sediment, rust, and suspended impurities, preventing contamination of subsequent filters and extending the lifespan of the entire filtration system. This initial filtration ensures the basic cleanliness of the water, laying the foundation for deeper purification.
After the first stage of filtration, the water passes through a dual-layer activated carbon filtration system. The first activated carbon filter primarily removes chlorine, odors, and certain organic compounds, while the second precision activated carbon filter further eliminates residual chemical pollutants, ensuring even higher purity. This dual activated carbon structure not only improves the taste of the water but also effectively reduces harmful substances.
As the core of the purification process, the fourth layer utilizes high-precision reverse osmosis (RO) membranes or ultrafiltration membranes for deep purification. The RO membrane can remove bacteria, viruses, heavy metal ions, and other microscopic contaminants, with a filtration precision of up to 0.0001 microns, achieving truly pure water. Meanwhile, the ultrafiltration membrane retains beneficial minerals, catering to different drinking water needs.
Finally, the water passes through the post-activated carbon filter for the final enhancement. This filter eliminates residual odors and improves the taste, making the drinking water fresher and more enjoyable. With this additional process, the purification system not only ensures health and safety but also delivers a superior drinking experience. Today, five-layer filtration systems are widely used in households, offices, and public drinking water facilities, providing a higher standard of safe water consumption. In the future, with continuous advancements in water purification technology, these systems are expected to become even smarter and more eco-friendly, bringing greater benefits to drinking water safety.
