Nanofiltration Systems
Custom-fabricated membrane skids designed for specific ionic separation. We engineer systems that deliver precise divalent ion rejection and superior flux stability.
- High rejection of divalent ions (90-98%)
- Operates at lower pressure than Reverse Osmosis
- Retains beneficial monovalent minerals
- Ideal for water softening & organic removal
Design & Engineering
The Problem with Generic Systems
Off-the-shelf membrane systems often fail to account for specific feed water chemistry and hydraulic balance.
Uneven Flux Distribution
Standard skids often suffer from hydraulic imbalances, leading to telescoping and premature fouling of lead elements.
Scaling & Fouling Risks
Without proper antiscalant dosing logic and cross-flow velocity modeling, membranes scale rapidly with divalent salts.
Mechanical Integrity
Poorly welded pipework and inadequate support structures lead to vibration fatigue and leaks under high-pressure operation.
Introducing Nanofiltration:
A Smarter Separation Technology
Nanofiltration (NF) is the "Goldilocks" of membrane technology—positioned perfectly between Ultrafiltration and Reverse Osmosis.
While RO removes almost everything and UF lets dissolved solids pass, NF is engineered to be highly selective. It targets divalent ions (like Calcium and Magnesium) and organics, while allowing smaller, benign monovalent ions to pass through.
This unique capability makes it the ultimate solution for water softening, pesticide removal, and process water treatment where total demineralization is unnecessary and inefficient.
Filtration Spectrum
Ultrafiltration (UF)0.01 µm
Nanofiltration (NF)0.001 µm
Reverse Osmosis (RO)0.0001 µm
*NF offers the optimal balance of rejection performance and operating pressure (Energy).
Technical Process
How Nanofiltration Works
Nanofiltration membranes feature a pore size of approximately 0.001 microns (10 Angstroms). This microscopic barrier acts as a selective sieve driven by pressure.
- 1
Separation
Water is pumped across the membrane surface at moderate pressure (3.5–16 bar).
- 2
Rejection
The membrane rejects divalent ions (like Ca²⁺, Mg²⁺, SO₄²⁻) and organic molecules >200 Daltons.
- 3
Passage
Monovalent ions (like Na⁺, Cl⁻) pass through more freely, resulting in treated water that is not "dead" but chemically stable.
