Pressurized Ultrafiltration Hollow Fiber Membrane
UF hollow fiber membrane modules is the preferred choice for treating and purifying various water resources including drinking water, industrial water and municipal effluent water, and is an excellent alternative for the pretreatment of seawater in desalination. Our UF membranes are also suitable for various separation processes such as biopharmaceutical, food and beverage, chemical, oil and gas, power generation, cooling water, environmental, etc. We have the capability to provide professional technical support that includes in-house design consultation, selection of optimal process flow and after sales support to our customers
Product features and benefits
• Excellent quality product water
UF hollow fiber membrane module utilizes membrane made from materials (PVDF,PVC)
depending on customer needs, and is capable of producing product water of reliable and consistent quality.
• Compact design and low energy consumption
With its efficient separation and high flux characteristics, small footprint can be achieved. Low filtration resistance
dictates lower energy consumption.
• Ease of maintenance
Minimal maintenance personnel required with full automation on system backwash and chemical-clean-in-place (CIP).
