7. Working Principle

PROC10 realizes efficient water purification, high desalination and high chemical stability based on the reverse osmosis principle, combined with high-crosslinking membrane material technology and spiral wound structure design. Osmosis is a natural phenomenon in which water molecules spontaneously flow from a low concentration solution to a high concentration solution. Reverse osmosis applies a pressure greater than the osmotic pressure on the high concentration side (raw water side), forcing water molecules to pass through the semi-permeable membrane to the low concentration side (produced water side), while retaining salts, organic matter, heavy metals and other harmful substances. The high-crosslinking aromatic polyamide composite membrane adopted by PROC10 has a dense structure and a pore size of only 0.1-0.2 nanometers, which only allows water molecules to pass through, ensuring high desalination rate. The high-crosslinking structure of the membrane material enhances its chemical stability, making it resistant to corrosion by acids, alkalis and other chemical substances. The optimized spiral wound structure makes the water flow evenly distributed on the membrane surface, generating a gentle scouring force, which can timely wash away the attached pollutants, delay membrane fouling, and ensure stable operation in complex water environments.

8. Future Prospects

With the increasing complexity of industrial production and environmental pollution, the demand for complex water quality treatment is constantly expanding, and PROC10, with its core advantages of high desalination rate and high chemical stability, has broad development prospects. In the future, this model will be intelligently upgraded, integrating Internet of Things and sensor technology to realize real-time monitoring of water quality, membrane performance and chemical stability, and automatic reminder of cleaning and maintenance, which is in line with the development trend of intelligent water treatment. It will also continuously optimize the membrane material crosslinking technology, further improve the desalination rate and chemical stability, and expand the applicable pH range and pollutant tolerance. At the same time, it will expand application scenarios to new energy, environmental protection and other emerging fields, promote the recycling of water resources, improve the recycling rate of waste membranes, and reduce environmental pollution. In addition, it will provide one-stop services, covering product supply, installation and commissioning, maintenance and technical guidance, to further improve user experience; at the same time, it will form a complementary product system with LFC-LD (low fouling, low energy consumption) to meet the needs of different water treatment scenarios.
