Application in Steel Mill Water Treatment

The Reverse Osmosis Equipment Model LFRO-30 is ideally suited for steel mill water treatment, addressing critical challenges:

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.
Wastewater Recirculation:
- Polishes wastewater for reuse in non-contact cooling, reducing freshwater consumption.
- Removes oils, greases, and suspended solids to meet discharge standards.
Boiler Feed Water:
- Filters dissolved solids and silica to prevent boiler tube fouling, improving energy efficiency and 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 LFRO-30 excels in diverse industries:

Food & Beverage: Purifies water for bottling, brewing, and cleaning.
Power Generation: Treats boiler feedwater and cooling water in thermal and nuclear plants.
Chemical Processing: Provides ultra-pure water for pharmaceutical and petrochemical applications.
Municipal Water Treatment: Produces potable water from brackish or contaminated sources.

Working Principle

The LFRO-30 operates on the principle of reverse osmosis, where feedwater is forced through a semipermeable membrane under pressure:

Pre-Treatment:
- Multi-media and activated carbon filters remove particulates, organics, and chlorine.
- Anti-scale dosing prevents mineral precipitation.
Reverse Osmosis:
- High-pressure pump drives feedwater through RO membranes, separating contaminants from purified water .
- Membranes reject dissolved solids, colloids, and microorganisms, producing water with <10 ppm TDS.
Post-Treatment:
- Conductivity meter monitors product water quality.
  – Concentrate control valve optimizes recovery rate while preventing membrane damage.
