Case study
360 m³/h Chemical Plant Reclaimed-Water Reuse Retrofit
This 360 m³/h retrofit upgrades a chemical plant wastewater system for reclaimed-water reuse. Filtration, ultrafiltration, two-stage reverse osmosis and mixed-bed polishing are combined to supply the production-water system.

Project overview
This 360 m³/h retrofit upgrades a chemical plant wastewater system for reclaimed-water reuse. Filtration, ultrafiltration, two-stage reverse osmosis and mixed-bed polishing are combined to supply the production-water system.
Plum supplied the complete process systems described for this project.
Process route
Multimedia filtration → hollow-fiber ultrafiltration → two-stage reverse osmosis → mixed-bed polishing
Process roles
Multimedia filtration and hollow-fiber ultrafiltration control impurities upstream of desalination. Reverse osmosis removes dissolved salts, followed by mixed-bed polishing. The ultrafiltration stage uses hollow-fiber membranes.
The reverse-osmosis section follows Plum’s HRCC design concept.
