Nanofiltration
A membrane process between UF and RO for selected dissolved species.
Safety boundary: this guide is conceptual. It does not provide chemical dosing recipes, pressure-system procedures, wastewater-entry instructions, UV/ozone exposure procedures, electrical work or machine operating settings.
What this topic covers
A membrane process between UF and RO for selected dissolved species.
Core water-treatment ideas
Nanofiltration can reject many multivalent ions and larger dissolved molecules.
Its selectivity differs from reverse osmosis and depends on membrane chemistry.
High-pressure membrane operation requires engineered equipment and qualified procedures.
Important limits
MF/UF and NF/RO address different size ranges and dissolved-contaminant problems.
What to monitor
Pretreatment, fouling, integrity and concentrate management are core lifecycle issues.
Lifecycle perspective
High-pressure membrane operation and cleaning require manufacturer and professional procedures.
