1. Membrane Material Composition The MBR internal support hollow fiber membrane made of PVDF is a new generation of high-performance products successfully developed by Beijing Haiden Energy Co., Ltd. after years of research. This membrane is produced using a phase inversion method, with an internal polyester tube as the support body, featuring high strength (tensile strength ≥20.0MPa), high resistance to peeling (peeling strength ≥1.0MPa), high porosity (≥60%), and high permeability (≥15L/m²·h-0.01MPa). The pore diameter of the PVDF internal support membrane is 0.01~0.1 μm. 2. MBR Membrane Components The MBR membrane components use hollow fiber membrane modules, with various product component forms that can be combined or separated according to user needs, making application more flexible. Users can select membrane components based on key parameters such as permeability, strength, filtration accuracy, and anti-pollution ability. High filtration accuracy can ensure product quality; high permeability can reduce project costs; high strength and anti- pollution ability can extend the service life of membrane components, reducing operational costs. Long-term R&D personnel have improved membrane components, enhancing product performance.

The HUF-2880 ultrafiltration membrane components are suitable for systems with a capacity greater than 50m³/hr (220gpm). The larger diameter membrane components (8 inches) have the largest effective membrane area among hollow fiber ultrafiltration membrane products, allowing for more economical system design. Compared to longer membrane components, shorter membrane components (60 inches) provide higher separation efficiency and can adapt to a wider range of water quality. Performance Features Ultrafiltration membrane components are made of high-strength PVDF material and have the following outstanding features and advantages: ● A nominal pore size of 0.03μm effectively removes bacteria, viruses, and particulate matter, protecting downstream equipment and reverse osmosis (RO) processes. ● The PVDF composite hollow fiber has high strength and excellent chemical resistance, extending the service life of the membrane components. ● The hydrophilic PVDF fiber is easy to clean and maintain, ensuring long-term performance stability.

Ultrafiltration (UF) membrane components are made of high-strength PVDF material, and their membrane fibers have the following characteristics and advantages: ● A nominal pore size of 0.03μm can remove bacteria, viruses, and particulate matter, protecting downstream equipment and reverse osmosis systems. ● High-strength, chemical-resistant PVDF composite hollow fiber membrane ensures a longer service life of the membrane components. ● The hydrophilic PVDF fiber membrane is easy to clean and wet, maintaining excellent performance over the long term. ● The external pressure structure can withstand higher influent suspended solids concentration and reduce pretreatment processes. ● The use of U-PVC material for the membrane shell eliminates the need for expensive pressure vessels. The HUF-2860 ultrafiltration membrane components are suitable for systems with a capacity greater than 50m³/hr (220gpm). The larger diameter membrane components (8 inches) have the largest effective membrane area among hollow fiber ultrafiltration membrane products, allowing for more economical system design. Compared to longer membrane components, shorter membrane components (6 inches) provide higher separation efficiency and are suitable for a wider range of water quality.

The FR (Fouling Resistant) series anti-fouling membrane elements are our company's independently developed composite membrane elements, featuring low operating pressure, high production capacity, and high salt rejection. The membrane surface has been modified with an anti-fouling patent technology to change the surface charge characteristics, increase hydrophilicity, reduce pollution and microbial adhesion, lower membrane fouling, extend service life, and use a 34mil wide channel design to reduce pressure loss and improve cleaning recovery. The Reverse osmosis membranes are suitable for water with low salinity (below 500ppm) such as municipal water and industrial water sources, mainly used for various scales of municipal water, boiler feedwater, and cooling water treatment, especially for slightly organic polluted water sources.

Resin Trap – A Safety Device for Resin Systems In any advanced water treatment system, the uncontrolled release of ion exchange resin or filter media can be disastrous. A sudden failure in a nozzle or underdrain system can send media particles downstream, clogging spray nozzles, fouling heat exchangers, and causing catastrophic damage to sensitive and expensive equipment. This leads to costly downtime, complex repairs, and compromised process integrity. A Resin Trap is your essential safety device and the most cost-effective insurance policy against these risks. Strategically installed, it acts as a final line of defense, safeguarding your entire downstream process. Resin Traps Filter media Trap for ion exchange How Do Resin Traps Work and Where Are They Installed? Essentially, a resin trap functions as a robust, precision-engineered in-line strainer. Its primary purpose is to intercept and capture any escaping ion exchange resin, activated carbon, or other filter media before it can travel further into your system. Optimal Placement: For maximum protection, resin traps should be installed directly on the outlet pipelines of all media-containing vessels, including: Ion Exchange (IX) Columns (Softeners and Demineralizers) Activated Carbon Filters Other Media Filtration Systems Many of our resin traps feature robust, transparent housings, allowing operators to effortlessly monitor for any signs of media leakage or debris buildup, enabling proactive maintenance and preventing major system issues. Key Advantages of Installing a Resin Trap Prevent Costly Media Loss: Secure your valuable ion exchange resin and filter media, preventing expensive replacement and recharge cycles. Protect Downstream Assets: Shield critical components like pumps, valves, and processing equipment from abrasive damage and clogging, extending their service life. Ensure System Integrity: Avoid cross-contamination of processes and guarantee the quality of your treated water by capturing any errant particles. Fully Customizable Solutions: We engineer each resin trap to meet the precise demands of your application, ensuring optimal performance and a perfect fit. Engineered for Durability and Performance We understand that every system is unique. That's why we offer extensive customization options to build a resin trap that perfectly matches your operational requirements. Material Selection: Choose from premium-grade materials selected for their exceptional resistance to corrosion, acids, alkalis, and high temperatures: Stainless Steel: 304/304L, 316/316L Durable Plastics: PVC, CPVC, and other specialized polymers Precision Filtration: Our wedge wire screen internals are available with slot sizes ranging from 3 mesh to 400 mesh (approx. 50 to 500 microns), providing the precise level of filtration needed to capture your specific media without impeding normal flow. Seamless Integration with Your System Our resin traps are designed for straightforward installation into new or existing pipework. Flanged Connections: Ideal for industrial applications, typically standard on our 3″ and larger stainless steel models. Stub-End Connections: Pre-installed pipe lengths allow for easy welding or coupling into your existing pipeline. Threaded Connections: A simple and reliable option for smaller lines, enabling quick screw-in installation. Critical Installation Advisory: Do Not Use on Backwash Lines It is crucial to avoid installing resin traps on backwash lines. A resin trap is designed to capture media, and in a high-flow backwash scenario, it will quickly clog. This creates significant back pressure, which can prevent the proper brine draw and regeneration of water softeners, leading to drastically reduced efficiency and potential damage to the system. wedge wire Resin Traps for water treatment Partner with YUBO for Reliable Filtration Solutions Don't leave your critical systems vulnerable.
