8-inch, Wide Inlet Channel, Fouling-resistant Brackish Water Desalination Membrane Elements
The JBW-8040-FR series membrane elements integrate JOZZON unique antifouling membrane and winding process, resulting in a long service life, good weather resistance, and customizable 36-40mil wide flow channels to further enhance antifouling capabilities.
Applied Industries
Industrial Wastewater Reuse
Wastewater from various industrial enterprises such as electronics, textiles, chemicals, steel, electroplating, petrochemicals, coal chemicals, and printing and dyeing undergoes preliminary treatment followed by deep desalination and recycling.
Power Plant Boiler Feedwater Treatment
Used for desalination of boiler feedwater in power plants, requiring stable effluent quality and extremely low salt content.
Industrial Wastewater Containing Small Amounts of Organic Pollutants
Particularly suitable for treating industrial wastewater containing small amounts of organic pollutants generated in food processing, printing and dyeing, and electroplating industries.
Advanced Municipal Wastewater Treatment
Reuse of secondary effluent from municipal wastewater treatment plants, suitable for scenarios containing trace amounts of organic matter and microorganisms.
Treatment of Slightly Polluted Water Sources
Treatment of surface water or groundwater slightly polluted by agricultural non-point source pollution or domestic sewage.
Other Industrial Water Treatment
Desalination plants in power plants, petrochemical plants, and steel mills.
Product Overview
The JBW-8040-FR series membrane elements incorporate JOZZON's unique antifouling technology in both membrane sheet and winding processes, effectively improving the membrane elements' resistance to fouling. Under the same operating conditions, these membrane elements have a longer service life and better weather resistance. Furthermore, our company's outstanding R&D capabilities allow us to customize feed channels with widths of 36mil-40mil for customers, further enhancing the antifouling capabilities of the membrane elements while ensuring sufficient permeate flow.
Features & Benefit
1. Unique Antifouling Membrane Technology
The membranes utilize JOZZON's independently developed antifouling technology, featuring strong surface hydrophilicity and optimized charge characteristics. This effectively reduces the adhesion tendency of pollutants such as organic matter, colloids, and microorganisms, minimizing fouling at its source.
2. Antifouling Rolling Process
Antifouling design concepts are incorporated into the rolling process, resulting in uniform membrane sheet distribution and a short permeate flow channel. This reduces dead zones for pollutant accumulation and enhances the overall fouling resistance of the membrane element.
3. Extra-Long Service Life and Weather Resistance
Under the same operating conditions, this series of membrane elements has a significantly longer service life than ordinary antifouling membranes and exhibits excellent weather resistance, adapting to fluctuations in water quality and environmental changes, reducing replacement frequency.
4. Customized Wide Flow Channel Design (36-40mil)
Leveraging its superior R&D capabilities, Jiuzhang can customize inlet flow channels with widths from 36mil to 40mil according to customer needs. While ensuring permeate flow, this further reduces pressure differential and enhances the water flow flushing effect, significantly improving antifouling performance.
5. Balancing High Productivity and Fouling Resistance
The wide-channel custom design does not come at the expense of productivity. By optimizing membrane and winding parameters, JOZZON ensures that high and stable product flux is maintained while enhancing fouling resistance.
