Main application areas of ultrafiltration membranes in China
The past 30 years have witnessed the rapid development of ultrafiltration technology, with ultrafiltration separation technology being widely applied in drinking water preparation, food industry, pharmaceutical industry, industrial wastewater treatment (electrophoretic painting wastewater treatment, oily wastewater treatment, polyvinyl alcohol (PVA) containing wastewater treatment, fiber processing oil wastewater treatment, color and dyeing wastewater treatment, pulp wastewater treatment, leather wastewater treatment, optical glass grinding wastewater treatment, photographic industry wastewater treatment), radioactive wastewater treatment, metal processing coatings, bioproduct processing, petroleum processing, and other fields. Large-scale water treatment is usually concentrated in the following aspects: drinking water supply terminal, surface

Application of membrane technology in industrial wastewater treatment and reuse
Membrane technology is applied in industrial wastewater treatment and reuse to recover valuable components from wastewater and reuse the permeate after removing impurities in relevant processes, saving resources and water while preventing environmental pollution. The earliest and most mature application is the use of reverse osmosis (RO) or electrodialysis (ED) technology to treat electroplating wastewater, such as wastewater containing nickel, chromium, copper, zinc, and other metals, recovering these metal ions and reusing the water for rinsing. Due to the high value of chromium and nickel reuse, many countries focus on the treatment of chromium-containing and nickel-containing wastewater. Another
China will continue to strengthen international cooperation in the field of water pollution control.
At the International Symposium on Water Pollution Prevention and Control in Veneto Region and China, held at the Italy Pavilion of the Shanghai World Expo on the 14th, Zhang Yufei, Deputy Director General of the Pollution Control Department of the Ministry of Environmental Protection, said that China will continue to strengthen international cooperation in the field of water pollution control. Zhang Yufei said that there is still a long way to go to truly achieve the goal of allowing rivers, lakes and seas to rest and rejuvenate, and the Chinese government needs not only its own efforts, but also to strengthen international cooperation, learn from developed countries with advanced management concepts and mature environmental technologies, and continue to deepen and expand cooperation in the field of water pollution control. "We hope that the Italian side can coordinate environmental protection and economic development.
