Fouling-Resistant Series Reverse Osmosis Membrane Element OV-FR-4040

Fouling-Resistant Series Reverse Osmosis Membrane Element OV-FR-4040 modifies the surface charge and smoothness of the membrane, increasing its hydrophilicity and effectively reducing fouling by colloids, organic matter, and other contaminants, significantly improving the membrane's cleaning and recovery performance. This innovative technology not only enhances the membrane's antifouling capabilities but also demonstrates significant advantages in long-term operational stability. In practical applications, after 1200 hours of continuous operation, the modified membrane element showed a 47% reduction in flux decay compared to traditional membranes—a figure verified by a third-party testing agency in a seawater desalination project. Its unique dual-effect protection mechanism—the synergistic effect of a physically smooth surface and chemical charge repulsion—allows the membrane module to maintain over 90% of its initial flux even when dealing with high-turbidity raw water.
Particularly noteworthy is the technology's outstanding effectiveness in controlling organic pollutants. Laboratory comparative tests show that when treating humic acid-containing wastewater, the modified membrane's surface contact angle decreased from 78° to 32°, and the absolute value of the zeta potential increased to -35mV. This combination of strong hydrophilicity and enhanced negative charge reduces the deposition rate of colloidal particles by 60%. Engineering case studies show that in an electronics factory's electroplating wastewater treatment system, the cleaning cycle of membrane modules using this technology was extended from 72 hours to 240 hours, saving 12 tons of chemical cleaning agents annually.
The Fouling-Resistant Series Reverse Osmosis Membrane Elements 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 Series Reverse Osmosis Membrane Elements 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.
