10" 20" Jumbo PVDF Hollow Fiber UF Filter BB10 BB20, for very muddy water ⬇read⬇

Description: This AQFS "MudEater" water filter is the perfect solution for those looking to clarify their water. With a 1-stage filtration system, it effectively removes sediment and other particles from your muddy water. The filter is compatible with Big Blue standard filter housing and is made of PVDF fiber and utilizes Outside-in* filtration mode. The unit weight of this filter is 2 lbs for 10" cartridge and 3 lbs for 20" cartridge, and it comes in a pack of 1. It is suitable for use in very muddy water and provides ultrafiltration method for superior clarity. This water filter is a must-have for anyone looking to purify their water.Works great in case you need to clarify water from muddy pond, also- as a pretreatment step before reverse osmosis (RO) or nanofiltration (NF) systems, or - you want to add to your household water a new power of purity.Effective in removing turbidity, bacteria, and viruses from water.To remove tannins might need dosing coagulant before the filtration.There are two diameters of fiber.2.0 mm fiber is the best solution when the water is very muddy and requires often to clean the membrane manually, because of its perfect mechanical strength.0.8 mm fiber provides high performance and productivity, is excellent when the maintenance fulfilled mostly automatically by backwashing the membrane with clean water. You may have to use an automatic cleaning (backwashing) system that contains solenoid valves, timer and pressure tank for storing clean wash water, in this case. If you have any questions don't hesitate to ask.

Here's a breakdown of specifics and performance aspects for Out-to-In PVDF UF membranes:1. Membrane Structure and ConfigurationOut-to-In Flow: This configuration refers to the direction of the feed flow, where the water or fluid passes from the outside of the hollow fiber membrane into the lumen (inner part) of the fiber.Material: PVDF is a semi-crystalline polymer known for its durability, and it's often used in a hollow fiber form for ultrafiltration membranes.Pore Size: UF membranes typically have pore sizes ranging from 0.01 to 0.1 microns, effectively removing suspended solids, bacteria, and some viruses.Porosity: PVDF membranes have high porosity (up to 70-80%), allowing for high water flux while maintaining filtration efficiency.2. Performance CharacteristicsPermeability: Out-to-In PVDF UF membranes exhibit high permeability, meaning they can process large volumes of water with relatively low pressure. Typical flux values can range from 50 to 150 LMH (liters per square meter per hour) depending on the operating conditions.Fouling Resistance: PVDF membranes are known for their good antifouling properties due to their hydrophobic nature. However, surface modifications, such as blending with hydrophilic polymers, can enhance fouling resistance.Chemical Resistance: PVDF is resistant to a wide range of chemicals, including acids, bases, and organic solvents, making it suitable for various industrial applications.Mechanical Strength: The hollow fiber structure provides excellent mechanical strength, allowing the membranes to withstand high transmembrane pressures (TMP), usually in the range of 0.1 to 1 bar.Temperature Stability: PVDF membranes can operate at higher temperatures compared to other polymeric membranes, often up to 90°C, which is beneficial for hot water applications.3. ApplicationsWater and Wastewater Treatment: Effective in removing turbidity, bacteria, and viruses from water. Widely used in municipal drinking water treatment and wastewater reuse.Industrial Processes: Utilized in various industries, including food and beverage, pharmaceuticals, and chemical processing, for separating particulates, proteins, and other macromolecules.Pretreatment for RO/NF Systems: Often used as a pretreatment step before reverse osmosis (RO) or nanofiltration (NF) systems to protect these more sensitive membranes from fouling.4. Cleaning and MaintenanceBackwashing: Periodic backwashing (reversing the flow direction) is common to remove accumulated solids from the membrane surface.Chemical Cleaning: Strong cleaning agents like sodium hypochlorite, citric acid, and caustic soda are used for cleaning PVDF membranes, owing to their chemical resistance.5. LimitationsHydrophobicity: While hydrophobicity provides fouling resistance, it can also cause initial wetting issues. Pretreatment with surfactants or wetting agents may be necessary.Cost: PVDF membranes tend to be more expensive than other polymeric membranes like polysulfone (PS) or polyethersulfone (PES).6. Performance MetricsRecovery Rate: Typically, PVDF UF membranes exhibit high water recovery rates (85-95%), minimizing waste and enhancing efficiency.Rejection Rate: These membranes provide high rejection rates for suspended solids and microorganisms, typically > 99%.7. Dead-end filtration method: How it works.In dead-end filtration, pressure is applied from the outside to the inside of a hollow fiber membrane, forcing the entire volume of fluid through the membrane without losing any fluid. This method creates a sedimentary (cake) layer on the membrane surface, which can trap particles smaller than the membrane's pores. To maintain performance, the cake layer is periodically removed through backwashing with permeate or chemical solutions. Dead-End Element Features:U-Shaped Design: One-sided potting in a U-shape enhances the element's structural strength.Chemical Resistance: The element can withstand chemical cleaning, allowing for back-pressure washing to restore permeability and maintain efficiency. Summary:Out-to-In PVDF UF membranes are robust, high-performance filtration solutions, particularly well-suited for applications requiring durability, chemical resistance, and efficient separation. Their ability to handle challenging water and wastewater conditions, combined with ease of cleaning, makes them a popular choice in various industries. * see a picture.
