PROCESS & EQUIPMENT DETAILS
How nanofiltration (nf) plant fits your process.
Operating principle
Membrane separation for selective dissolved-solids treatment and water reuse applications.
Pressure drives water through a semipermeable membrane. The feed separates into permeate and a concentrate stream; recovery and membrane arrangement are established from water chemistry and a membrane projection.
Engineering checks
- Feed ionic analysis, temperature, SDI and turbidity
- Scaling potential at proposed recovery
- Element flux, crossflow and pressure limits
- Permeate quality and concentrate-management route
Configuration & equipment
- Feed conditioning and cartridge filtration
- High-pressure feed pump
- Membrane pressure housings
- Spiral-wound membrane elements
- Permeate and concentrate manifolds
- Pressure, conductivity and flow instruments
- Cleaning connections and control panel
Configuration options are reviewed against the project duty. Supply quantities and final scope are defined in the approved proposal.

A solution shaped by your requirements.
Membrane separation for selective dissolved-solids treatment and water reuse applications. The process train is selected from feed-water analysis and the final water specification. Pretreatment protects downstream treatment, while monitoring and cleaning provisions support reliable operation.
What we review
- Required product flow and operating hours
- Water source and complete laboratory analysis
- Feed temperature, pH and fouling indicators
- Target water quality and intended use
- Utility availability and plant footprint
- Pretreatment and cleaning requirements
Capacity, materials, operating conditions and performance are specified after review of your project data. Product images are conceptual visualizations.
From design to operation
