Cost Reduction Analysis: Cold Bleach Rinse Water Reuse

Many textile bleaching operations have counter flow washers for rinsing of post bleached fabric.

After a hot rinse, a cold rinse is used as a final rinsing step. Many operations control flow for both the hot and cold rinse make-up waters.

Average washers discharge the contaminated cold rinse water to a wastewater system at 25 gallons per minute.

The EnviroSep Fluid Recovery System cleans the wastewater recovering 90% of the water for reuse in the washer or plant hot water system.
