● Product performance and characteristics
Antioxidant (CR) series is developed by OVAY Technology for desalting brackish water containing micro-oxidizing substances. It has the characteristics of high desalting rate and large flux. It adopts special preparation technology to enhance the oxidation resistance of membrane elements and can bear the impact of a certain amount of oxidizing substances. It can be widely used in municipal water supply, reclaimed water reuse, surface water reuse, coal chemical industry, thermal plants boiler make-up water, food industry water, textile printing and dyeing, electroplating industry and other fields.
