? DONGYANG^TMexteal pressure type SFX-N series module by NIPS(wet process) preparation of PVDF hollow fiber ultrafiltration membrane, with a long service life, high throughput, high anti-pollution capacity, water quality and stability characteristics.

? DONGYANG^TM SFX-N Series ultrafiltration components structure of exteal pressure, selectable dead-end filtration, flow, runs two ways, ensuring that more than 90%.

? DONGYANG^TM SFX-N Ultrafiltration using the safe and reliable design, gas flow distribution, water quality more broadly, the product can remain stable and reliable under extreme operating conditions.

? The company is based on many years of continuous innovation, development and investment, large-scale use in desalination, water And preparation of ultrapure water pretreatment and wastewater, water reuse and other fields.

SEM

》Long service life

? PVDF membrane material, oxidation resistance, high chemical resistance;

? Double seals at both ends, soft flexible roots not easily broken;

? Proprietary blend formula, high compressive and tensile strength

》High flux and low energy consumption

? High surface porosity and uniform pore size, membrane resistance, high water flux;

? Exteal pressure structure, high filtration efficiency, large amount of dirt, easy to clean

》Water quality stability

? Nominal pore size of 0.03 μ m,PVDF membrane material sieve apertures in the smallest one of the manufacturers;

? Membrane composed of a dense layer and the layer structure, high retention rate;

? Patented hydrophilic modification of permanent water, greatly improved stain resistance.
