HT-NF30-8040 Nanofiltration Membrane

Product Introduction

◎ Product Introduction and Application Fields

　　As a standardized industrial-grade membrane element, nanofiltration membranes have become the core choice for large-scale separation and purification processes thanks to their key advantages: high selectivity, high throughput, strong anti-fouling performance, and broad compatibility. Their applications span across multiple critical sectors—including water treatment, food and beverage, biopharmaceuticals, chemical and environmental protection, and new energy—meeting both the core demands of water quality purification and product refinement while also enabling resource recovery and achieving environmental goals such as energy conservation and emission reduction. They are an essential piece of equipment supporting the green upgrading and high-quality development of industry.
