Caustic Recovery Plant
Recover NaOH. Reduce
Cost.
Rototech's caustic recovery plants use MEE or MVR evaporation to reconcentrate dilute sodium hydroxide from textile mercerising and dyeing operations — achieving 95%+ recovery and near-zero liquid discharge.

Caustic Recovery Questions
For most textile mercerising units, the payback period is typically 12 to 18 months. This is driven by massive savings on fresh NaOH purchase and reduced acid requirements for effluent neutralisation.
Yes. By integrating effective lint filtration and controlled evaporation, the recovered NaOH is clear and suitable for immediate reuse in the mercerising machine without affecting fabric quality.
Rototech offers modular CRP systems starting from 1,000 litres per hour. Small mills can benefit from our single-effect or double-effect skid-mounted units which are easy to install and operate.
