Application in Steel Mill Water Treatment

The Ultrafiltration Equipment Model LFUF-15 is ideally suited for steel mill water treatment, addressing critical challenges:

1. Circulating Water Filtration:

• Removes iron, scale, and particulates from cooling water systems, preventing equipment corrosion and scaling.

• Ensures consistent water quality for blast furnaces, rolling mills, and other critical processes.

2. Wastewater Recirculation:

• Polishes wastewater for reuse in non-contact cooling, reducing freshwater consumption.

• Removes oils, greases, and suspended solids to meet discharge standards.

3. Boiler Feed Water:

• Removes suspended solids and silica to prevent boiler tube fouling, extending equipment lifespan.

Key Benefits for Steel Mills:

• Sustainability: Reduces water intake and wastewater discharge.

• Cost Savings: Lower freshwater and chemical treatment costs.

• Process Reliability: Consistent water quality ensures stable production.

Other Industrial Applications

The LFUF-15 excels in diverse industries:

1. Food & Beverage: Purifies water for bottling, brewing, and cleaning.

2. Pharmaceutical: Provides ultra-pure water for drug manufacturing and sterilization.

3. Agriculture: Treats irrigation water to remove pathogens and improve crop yields.

4. Environmental Protection: Processes wastewater for reuse in industrial and municipal settings.

5. Textile & Dyeing: Recovers dyes and chemicals from wastewater, reducing resource waste.

Working Principle

The LFUF-15 operates on the principle of ultrafiltration, a pressure-driven membrane process that separates contaminants based on molecular size:

1. Pre-Treatment:

• Multi-media and activated carbon filters remove particulates, organics, and chlorine.

• Dosing system adds chemicals to prevent scaling or enhance coagulation.

2. Ultrafiltration:

• High-pressure pump drives feedwater through PVDF hollow fiber membranes.

• Membranes retain particles, colloids, and macromolecules (retentate), while allowing water and small solutes to pass through (permeate).

3. Backwash Cycle:

• Periodically reverses flow to flush accumulated contaminants from membranes, maintaining performance.
