Nanofiltration Membranes

NF membrane technology for selective separation and water chemistry control

Alcedo develops, manufactures and commercialises nanofiltration membranes for water treatment applications requiring hardness reduction, selective separation, dissolved organic matter management and refined water quality control.

Our NF membrane technology supports industrial water treatment, process water systems and specialised treatment applications where water chemistry and separation performance affect system operation.

Nanofiltration membranes for treatment system performance

Nanofiltration is a pressure-driven membrane separation process. Water passes through a semi-permeable membrane while selected dissolved species, organic compounds and other materials are retained according to membrane specification, water chemistry and operating conditions.

NF membranes are used where facilities need selective membrane separation, hardness reduction, divalent ion reduction, dissolved organic matter management, colour reduction, process conditioning or water quality refinement.

Alcedo supplies nanofiltration membrane technology for facilities and project teams that need practical membrane solutions supported by technical understanding, internal testing, Australian technology development and manufacturing under ISO 9001 systems.

What nanofiltration membranes support

Alcedo nanofiltration membrane technology supports:

Selective separation
Hardness reduction
Divalent ion reduction
Dissolved organic matter management
Colour reduction
Water quality refinement
Process conditioning
Permeate quality control
Membrane replacement programs
Treatment upgrades and refurbishments

Nanofiltration is useful where water treatment requires controlled separation and water chemistry management rather than broad removal alone.

What affects nanofiltration membrane performance

Nanofiltration membrane performance depends on the membrane, the feedwater chemistry and the operating conditions of the treatment process.

Key considerations include feedwater quality, target separation requirements, hardness concentration, divalent and monovalent ion composition, dissolved organic matter, colour, membrane specification, flux, transmembrane pressure, recovery targets, fouling risk, scaling risk, pretreatment effectiveness, cleaning requirements, pH, temperature and permeate quality targets.

Alcedo helps connect NF membrane selection with practical water chemistry requirements, treatment objectives and long-term system operation.
