• DONGYANGTMexteal 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.

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

• DONGYANGTM 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


• Characteristics of ultrafiltration technology

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.
