With nanofiltration and reverse osmosis as the core, it has unique advantages in improving product quality, reducing the damage of heat-sensitive substances, and reducing the cost of concentration. Therefore, it is widely used in pharmaceutical, dye chemical, food and other industries, enabling desalination and impurity removal in the production process to be carried out simultaneously. For dye manufacturers, while improving product yield and quality, they can recover useful substances and reduce pollutant emissions.

With microfiltration, ultrafiltration, nanofiltration, and reverse osmosis as the core, combined with traditional water treatment methods, it not only provides high-purity water for industrial production, but also solves the problem of high-concentration industrial wastewater, seawater desalination, and domestic sewage discharge and resource utilization. Technical problems have been applied to the treatment and reuse projects of electroplating wastewater, circuit board rinsing water, papermaking wastewater, iron and steel production wastewater, domestic sewage, printing and dyeing wastewater, car washing wastewater, seawater desalination, etc.
