Ultrafiltration
Tighter membrane filtration for colloids, macromolecules and selected microorganisms.
Water-system note: treatment requirements depend on source water, intended use, equipment, permits and local rules. Real systems require qualified design, operation and laboratory verification.
What this topic covers
Tighter membrane filtration for colloids, macromolecules and selected microorganisms.
Core water-treatment ideas
UF provides a finer barrier than microfiltration.
It can protect downstream RO by reducing suspended and colloidal fouling loads.
Membrane integrity and fouling trends matter to reliable operation.
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.
