Product Overview
This high-efficiency nanofiltration (NF) membrane concentration system adopts advanced selective separation technology, using pressure-driven nanofiltration membranes to realize molecular-level concentration, purification and desalination in one step. It operates at room temperature with no phase change, effectively protecting heat-sensitive materials while greatly reducing energy consumption. Widely used in pharmaceutical extraction, food processing, chemical wastewater, beverage concentration and other industrial scenarios.
Core Advantages
High Precision Separation
Energy Saving & Low Consumption
Molecular weight cut-off (MWCO) 150–1000 Da, efficiently retains organic matter, peptides, functional components, and selectively permeates monovalent salts, achieving concentration + desalination synchronization.
Room-temperature operation, energy consumption only about 10–20% of traditional evaporation concentration, obvious cost reduction effect.
Anti-Fouling & Long Service Life
Compact & Modular Design
Intelligent Automatic Control
Optimized membrane surface and flow channel design, strong anti-pollution ability, easy to clean, stable long-term operation.
Small footprint, skid-mounted structure, plug-and-play, easy installation and commissioning.
PLC + touch screen, automatic operation, data monitoring, alarm protection, stable and reliable.

Working Principle
The core of the membrane concentration system is the selective permeable membrane (such as ultrafiltration membrane, nanofiltration membrane, reverse osmosis membrane), combined with "pressure-driven" or "concentration differentially driven" to achieve separation and concentration. The specific process can be divided into three steps:
Driving force effect:
Membrane sieving and separation:
The concentration process continues:
With a certain pressure (such as 0.5-4.0MPa commonly used for reverse osmosis membranes and 0.1-0.7MPa commonly used for ultrafiltration membranes) as the power, the material liquid to be concentrated (such as Chinese herbal extract, fruit juice, fermentation liquid) is transported to the "material liquid side" of the membrane module.
When the feed liquid flows on the membrane surface, the "precise pore size" (or charge effect) of the membrane selectively allows small molecule solvents (such as water molecules) to pass through the membrane pores and enter the "permeable side" to form "permeate" (which can be recycled or discharged up to standard). However, macromolecular solutes (such as polysaccharides, proteins, pigments, and active ingredients) are retained on the "feed liquid side" as they cannot pass through the membrane pores.
As the solvent continuously passes through the membrane, the solute concentration on the feed liquid side gradually increases and the volume gradually decreases, eventually reaching the preset concentration ratio (such as concentrating the solid concentration of traditional Chinese medicine extract from 5% to 20%), and the "concentrated liquid" is discharged from the system.
Application Scenarios
