Advanced Filtration Solutions for Steel Mills

In the high-stakes world of steel manufacturing, water systems are the lifeblood of operations. For one steel plant, declining performance of their shallow sand filters and quartz sand filters threatened both productivity and compliance. Enter LEFILTER, delivering a 30-day, $3.1 million overhaul that set new benchmarks in filtration technology.

Key Interventions

·         Shallow Sand Filters (400 m³/h): Replaced 2,400 kg of caked anthracite media, repaired 14 fractured distributor arms, and upgraded 3-phase control panels to prevent valve leakage.

·         Dual Cyclone Separators (Φ3500): Reconditioned the fibrous media bed, eliminating flow restrictions that had reduced processing capacity by 40%. New anti-abrasion linings extended service life by 60%.

·         Quartz Sand Filters (Φ3600): Addressed 18 instances of sand migration by installing stainless-steel underdrains and refilling with #00 crushed quartz (12 tons total).

Results

·         Suspended solids reduced from 500 ppm to 8 ppm.

·         Energy consumption for filtration dropped by 22%.

·         Client saved $1.2 million/year in water procurement costs.

At LEFILTER, we don’t just fix equipment—we engineer the future of water sustainability.
