● Product performance and characteristics
The fouling-resistant (FR) series membrane elements of OVAY Technology adopt special technology to treat the membrane surface, which changes the charge and smoothness of the membrane surface, increases the hydrophilia of the membrane surface, effectively reduces the fouling of colloid, organism and other fouling, and greatly improves the cleaning and recovery performance of the membrane. At the same time, the 34mil wide inlet water runner design is adopted, which further strengthens the fouling-resistant ability and better washability of membrane elements.
The fouling-resistant (FR) series membrane elements of OVAY Technology have the characteristics of high desalination rate and large flux, which are suitable for desalination of the surface water with salt content below about 10000 ppm, such as groundwater, tap water, and municipal water. They can be widely used in various industrial water treatment such as industrial reclaimed water reuse, municipal water supply and surface water reuse, coal chemical industry, thermal plants boiler make-up water, etc., especially suitable for the treatment of industrial wastewater containing a small amount of organic pollutants and micro-polluted water sources.
