Unique Laundry Effluent Treatment System

Utilizing Veolia's CeraMem® Ceramic Membrane Technology

Industrial Laundry Wastewater Treatment

Water is one of the most critical components in industrial laundries. Costs are associated with the large volumes used and subsequent disposal of detergent-laden wastewater.

Veolia Water Technologies, with a long history of successful installations in industrial laundries, has developed a system that offers substantial savings in water, power consumption, detergent, and sewer costs. Based on CeraMem® ultrafiltration (UF) ceramic membranes, these systems provide an effective technology platform for laundry applications.

Modular, Automated, and Fully Integrated

The system is supplied as a compact, modular unit with flexible features and capacities that can be fully integrated into each unique laundry.

All tanks, pumps, instrumentation, controls and other ancillary equipment are supplied by Veolia. As a total solution, each system is adapted to each laundry's needs and based on a pre-engineered, modular design.

System Features:

  • Pre-engineered, modular system
  • Flexible, scalable capacity from 50-250 gpm
  • Utilizes full-size CeraMem® UF membranes
  • American Technology, Engineering & Equipment

High Recovery Rates:

  • 50-70% as stand-alone unit
  • >90% with RO system for chloride removal

System Benefits

  • Water and heat recovery: Water reuse reduces makeup water costs
  • Decreased energy consumption
  • Increased water quality for reuse, even on critical white laundry applications: <5 mg/l suspended solids • <5 mg/l dispersed oils & greases ensures quality of laundered product
  • Reduction in regulated contaminants to minimize POTW surcharges and penalties
  • Predictable monthly water usage
  • Less chemical usage and reduced operating costs
  • Simple system integration
