What is Commercial Laundry Water Recycling?

Commercial laundry water recycling is an advanced filtration and treatment process that captures, cleans, and reuses water from washing machine rinse cycles. The technology removes lint, detergent residues, dirt particles, and contaminants, producing clean water suitable for reuse in subsequent wash cycles.

The Basic Principle

Modern washing machines use a multi-stage wash process. The initial wash cycles use the most water but also introduce the most contamination. The final rinse cycles use clean water but don't become heavily contaminated. Water recycling systems capture the water from the washing machines, filter it to remove all contaminants, and store it for reuse in the next machine's wash stages.

Who Benefits Most?

High-Volume Facilities:

• Hotels processing 3+ tonnes/day
• Hospitals with on-site laundries
• Aged care facilities
• Textile rental companies
• Industrial laundries (20+ t/week)

Cost/Regulation Pressures:

• High water/sewer costs
• Water restrictions or scarcity
• Trade waste discharge limits
• Sustainability commitments
• Green certifications

How Does the Technology Work?

Modern water recycling systems use a sophisticated multi-stage filtration process that rivals or exceeds municipal water treatment standards. Here's the complete process breakdown:

5-Step Process Flow

Wash Water

Wash cycle water exits tunnel washer or water extractors

Disc Filtration

Advanced disc filtration removes particles and contaminants

Heat Recovery

Thermal energy in the filtered water captured and reused

Clean Water Return

Filtered warm water returns to washing process at higher temperature

Cloud Monitoring

Continuous performance tracking and predictive maintenance alerts

🔬 Water Quality Standards

The multi-stage filtration process produces water quality that meets or exceeds New Zealand standards for commercial laundry reuse. Regular testing ensures consistent quality and washing performance.
