KC-UF Ultrafiltration Membranes & PVDF UF Modules

KC-UF超滤膜元件和PVDF中空纤维超滤模块

KC-UF ultrafiltration products are developed for water pretreatment, turbidity removal, suspended solids reduction, and industrial filtration applications. The product range includes standard UF membrane elements such as KC-UF-8040 and KC-UF-4040, as well as PVDF hollow fiber UF modules for municipal and industrial water treatment systems.

PVDF is supplied as the standard membrane material for the hollow fiber UF module series, offering stable filtration performance, good chemical resistance, oxidation resistance, hydrophilic performance, and mechanical strength. Other membrane material options, including PES, PS, PAN, and PVC, may be available upon request according to application requirements and system design.

Product Range

1.Standard UF Membrane Elements
KC-UF-8040 and KC-UF-4040 are standard-size ultrafiltration membrane elements for water pretreatment, industrial filtration, and E-Coat process applications. Depending on system requirements, they can be supplied for conventional water treatment or electrocoat paint recovery applications.

2.PVDF Hollow Fiber UF Modules
The KC-UF PVDF hollow fiber module series is designed for larger-capacity municipal water treatment, 中水回用, wastewater advanced treatment, and industrial process water applications. These modules use outside-in filtration and are suitable for systems requiring stable flux, anti-fouling performance, and backwashable operation.

3.E-Coat UF Membrane Elements
KC E-Coat UF membrane elements are PVDF spiral-wound ultrafiltration elements designed for electrocoat paint recovery and bath filtration systems. They are suitable for anodic and cathodic electrocoat processes, helping recover paint solids, maintain bath stability, and reduce wastewater discharge in coating lines.

常问问题

Q1. Are other UF membrane materials available besides PVDF?
是的. PVDF is supplied as the standard material for the hollow fiber UF module series. PES, PS, PAN, and PVC material options may be available upon request according to project requirements and system design.

Q2. Can UF be used as pretreatment before RO or NF systems?
是的. UF is widely used before RO and NF systems because it helps reduce turbidity, suspended solids, colloids, and SDI, supporting more stable downstream membrane operation.

第三季度. 是否可以定制?
Customization is available for membrane material, module configuration, interface design, and operating parameters based on system requirements.

第四季度. Can KC-UF membrane elements be used for E-Coat applications?
是的. KC-UF membrane elements can be supplied for electrocoat paint recovery and bath filtration applications. PVDF spiral-wound UF elements are commonly used in anodic and cathodic E-Coat systems, depending on paint type and process design.
