Coating & Surface Treatment
Coating Line Deionised Rinse Water
Deionised water supply and rinse water recovery for an industrial coating and surface treatment plant.
Challenge
Project Requirements
Rinse tanks consumed large volumes of deionised water and dragged out chemicals, driving both water cost and effluent load.
Engineered Solution
- RO plus mixed-bed deionisation for fresh rinse water
- Counter-flow rinse arrangement to minimise consumption
- Ion exchange recovery loop returning purified rinse water to the line
- Automatic conductivity control on each rinse stage
Results
Outcome On Site
Rinse water consumption cut significantly
Chemical drag-out losses reduced
Stable rinse conductivity improving coating quality
