Ultrafiltration Equipment Model LFUF-4 Applied In Pharmaceutical Water

Introduction

The LFUF-4 Ultrafiltration (UF) System, developed by XINXIANG LIFEIERTE FILTER CORP., LTD, is a state-of-the-art solution for industrial and municipal water treatment. Designed to remove suspended solids, colloids, bacteria, and macromolecular organic compounds, the LFUF-4 ensures consistent high-purity water output for critical applications such as pharmaceutical production, food and beverage processing, and wastewater reuse. Leveraging advanced hollow-fiber membrane technology, this system combines efficiency, durability, and ease of maintenance, making it a cost-effective choice for diverse industries.

Technical Specifications

The LFUF-4 is engineered for optimal performance under varying operational conditions. Key specifications include:

Note: Specifications are validated under ISO 9001-certified testing conditions.

Working Principle

The LFUF-4 employs crossflow ultrafiltration to achieve efficient separation:

1. Feedwater Intake: Raw water is pumped into the system and directed through a pre-filter to remove large particles.

2. Membrane Filtration: The pressurized feed flows tangentially across the hollow-fiber membrane surface. Water and small molecules (<0.1 μm) permeate through the membrane pores, while suspended solids, bacteria, and macromolecules are retained.

3. Backwash Cycle: Periodic reverse flushing with permeate water dislodges accumulated contaminants, maintaining membrane flux and extending service life.

4. Permeate Collection: Purified water is collected for use, while concentrated contaminants are discharged as reject water.

This process ensures >99.9% turbidity removal and LRV ≥6 for bacteria, meeting stringent purity standards.

Performance & Advantages

The LFUF-4 outperforms conventional filtration systems with its robust design and advanced features:

Key Advantages

• High Efficiency: Removes particles, colloids, and pathogens without chemicals.

• Low Energy Consumption: Operates at low pressure (15–45 psi), reducing operational costs.

• Chemical Resistance: PES membranes withstand aggressive cleaning agents (e.g., NaOH, HCl).

• Automated Operation: Integrated PLC controls backwash cycles, pressure monitoring, and alarms.

• Compact Design: Modular structure saves space and allows scalability.

Performance Metrics

Product Structure

The LFUF-4 features a modular, user-friendly design:

1. Pre-Filtration Unit: Includes a 20-μm cartridge filter to protect the UF membrane.

2. Hollow-Fiber Membrane Module: Contains thousands of PES fibers with a total surface area of 40 m².

3. Stainless Steel Housing: Corrosion-resistant 304 SS construction for durability.

4. Backwash System: Automated pumps and valves for efficient membrane cleaning.

5. Control Panel: Touchscreen PLC interface for real-time monitoring of pressure, flow, and turbidity.

Application in Pharmaceutical Water

Pharmaceutical water systems require zero endotoxins and ultra-low microbial counts. The LFUF-4 is ideal for:

• Purified Water (PW) Production: Removes particulates, pyrogens, and bacteria to meet USP/EP standards.

• Pretreatment for RO Systems: Reduces RO membrane fouling by eliminating colloids and organics.

• WFI (Water for Injection) Support: Ensures feedwater quality for subsequent distillation or RO polishing.

Case Study: A pharmaceutical facility in Asia reduced bacterial counts by 99.99% and achieved 24/7 compliance with pharmacopeial standards after installing the LFUF-4.

Other Applications

Beyond pharmaceuticals, the LFUF-4 serves diverse industries:

1. Food & Beverage: Clarification of juices, dairy processing, and brewery water treatment.

2. Electronics: Ultra-pure water for semiconductor manufacturing.

3. Municipal Water: Surface water treatment and wastewater reuse.

4. Chemical Industry: Process water purification and emulsion separation.
