Case study
24 m³/d RO Brine Reuse and Salt-Separation Pilot
This 24 m³/d pilot treats RO brine from coal-chemical production. Ultrafiltration and two-stage nanofiltration are combined to evaluate water reuse and selective salt treatment.
Project overview
This 24 m³/d pilot treats RO brine from coal-chemical production. Ultrafiltration and two-stage nanofiltration are combined to evaluate water reuse and selective salt treatment.
Plum supplied the complete process systems described for this project.
Process route
Ultrafiltration pretreatment → two-stage nanofiltration → validation of reuse and crystallization routes
Process roles
Ultrafiltration controls impurities upstream of nanofiltration, while nanofiltration provides selective salt separation. The pilot generates operating and separation data for evaluating subsequent process routes.
