Membrane Concentration System for Polyphenols and Flavonoids

Product Description

Plant Extract Membrane Filtration System

Membrane Separation & Concentration Equipment for Herbal and Botanical Extracts

Doupu provides industrial membrane filtration systems for plant extract clarification, purification and concentration.
Our MF, UF and NF membrane systems help process manufacturers reduce suspended solids, concentrate target compounds and improve process efficiency while minimizing unnecessary thermal exposure.

Common Problems in Plant Extract Processing

Plant extracts often contain fine particles, colloids, polysaccharides and other dissolved substances that can make filtration and concentration difficult.
Common challenges include:

1. High turbidity after extraction
2. Membrane fouling
3. Difficult clarification
4. Long concentration time
5. Heat-sensitive active ingredients
6. High energy consumption during processing

Our Membrane Solution

Depending on the raw material and processing objective, different membrane technologies can be selected:

Membrane Technology	Application
MF	Removal of suspended solids and fine particles
UF	Clarification and separation of macromolecules
NF	Selective concentration and fractionation of suitable dissolved compounds
RO	Water removal and concentration of suitable aqueous streams

The membrane type, MWCO and operating parameters should be selected according to the actual extract composition and target product.
