Nanofiltration (NF)
Greenchain Group delivers advanced Nanofiltration (NF) solutions for effective water softening and targeted contaminant removal. Operating at lower pressures than Reverse Osmosis, NF provides a practical balance of treatment performance, energy efficiency and water recovery. Our systems are designed around each application's specific water quality and operational requirements.
As a Turnkey Provider, our team designs and manufactures NF systems using high-quality local and international components, combining membrane technology expertise with cost-effective engineering. From process design through to installation, maintenance and ongoing optimisation, we provide a complete solution built for reliable long-term performance.
How does Nanofiltration (NF) work?
Nanofiltration (NF) uses pressure to pass liquid through a membrane, separating specific contaminants. Contaminant rejection depends on the membrane's density, with NF porosity typically falling within 1 to 10 nanometers (nm). This membrane density allows NF to target divalent molecular impurities like hardness, colourants, toxins, and more. It ensures consistent water quality on the permeate side, even amid inlet fluctuations, while diverting unwanted elements to the waste stream. NF, owing to its versatility and precision, finds an extensive array of applications across various industries.
Benefits of Nanofiltration (NF) for your business
Contaminant Removal
Removes divalent ions such as calcium and magnesium, along with organic matter and selected microorganisms, depending on the membrane and application.
High Purity
Produces treated water with significantly reduced levels of targeted impurities, supporting consistent water quality for business and process requirements.
Reduced Energy Consumption
Operates at lower pressures than Reverse Osmosis in many applications, helping reduce power consumption and lower long-term operating costs.
Compact Design
Modular membrane systems can deliver effective treatment within a relatively small footprint, with capacity that can be scaled as operational needs change.
Versatility Across Applications
Can be configured for different feed-water qualities and treatment objectives across industrial, agricultural, municipal and commercial applications.
Lower Chemical Requirements
Targeted membrane separation can reduce the need for chemical treatment, supporting more efficient resource use and lower chemical requirements over the life of the system.

NF Maintenance & Servicing
Keep Performing Optimally
Our nanofiltration (NF) maintenance and servicing programmes make it easier to keep your system performing reliably. We build an ongoing relationship with your team, taking care of key maintenance requirements and helping identify changes in membrane performance before they affect your operation.
Our NF servicing includes:
-
Pre-filter replacement
-
Antiscalant and antifouling chemical top-ups
-
NF membrane cleaning (CIP)
-
Leak detection and system checks
-
Membrane performance monitoring
Regular servicing helps manage membrane fouling, maintain consistent filtration performance and reduce operational risk and downtime, giving you a trusted team to turn to when your system needs attention.
Featured Project
Nanofiltration solution for a luxury game lodge
The project addressed persistent calcium scaling caused by mineral-rich borehole water, which was impacting guest facilities and placing unnecessary strain on critical infrastructure. Using advanced nanofiltration membrane technology, the system provides softened water throughout the lodge, protecting pools, plumbing infrastructure and equipment while improving operational efficiency and reducing maintenance requirements.
