Four types of membrane filtration, namely microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO),
are generally used to help with achieving the goals of our customers in the Dairy Industry.
Main applications:
1. Whey protein clarification & concentration
2. Protein-standardised milk
3. Bacteria removal
4. Preconcentration of milk for cheesemaking
5. Lactose concentration
6. Whole milk, skimmed milk concentrate
We produce sanitary RO, NF, UF, MF membrane for dairy industrial.
We use FDA starndard raw material to meet the sanitary request.

Applications:
Our spiral membranes for nanofiltration and reverse osmosis are used for a wide range of high-sanitary processes
in the food, beverage, dairy, biotech and pharmaceutical industries such as:
• concentration and purification
• fractionation
• extraction
• product recycling and recovery
• product and effluent upgrading
Why us?
We brings a knowledge-based approach to the supply of membrane products for dairy processing.
Our most important resource is our staffs, who have years of combined experience in dairy membrane filtration and process technology.
For raw material, we use the highest quality membrane sheet in the world.
Automatic rolling machine to keep the steady good performance.
To start business, we offer free testing samples to help you understand well.
