Renewable Design for Preparation Of Natural Pigments - Nanofiltration Membrane elements – Bona Group

1. Accurate MWCO.
2. Convenient to replacement of membrane.
3. No dead corner design, not easy to pollute.
4. Imported high-quality membrane materials, large flux and high stability.
5. Various specifications of membrane elements are available.
6. The filling density is high and unit cost is low.

We provide a variety of spiral type nanofiltration membrane elements with fine MWCO, which have compact structure and reasonable surface area / volume ratio. By using different flow channel networks, (13-120mil) can change the width of the feed liquid flow channel to adapt to the feed liquid with various viscosities. In order to meet the application of some special industries, we can select suitable nanofiltration membranes for customers according to their process requirements, different treatment systems and relevant technical requirements.
