Caustic Recovery System — CaRe®
Patented membrane based filtration for recovering spent caustic from textile mercerization and chemical manufacturing with wide pH compatibility.

Patented Technology
Spent Caustic Management Shouldn't Be a Cost Burden
The Challenge
Industries using caustic soda generate high strength wastewater with color, oils, and fibers. Traditional disposal increases chemical costs and environmental load.
Our Solution
CaRe® enables real time caustic recovery using specialized membrane filtration for direct reuse in production lines.
- Removes colorants, oils, and particulates without losing caustic strength
- Operates across wide pH range (1–14)
- Reduces acid consumption and sludge generation
- Integrates with textile production lines and ETP systems
- High temperature resistant membranes
- Fully automated with minimal operator intervention
CaRe® transforms waste alkali into valuable reusable caustic for textile, pulp & paper, and chemical manufacturers.
