Curtain-type Ultrafiltration Membrane Assembly

    I. What is curtain-type ultrafiltration membrane assembly?

Curtain-type ultrafiltration membrane assembly is a membrane separation technology used for water treatment. Shangchen Environment removes suspended matter, bacteria, viruses and macromolecules from water through ultrafiltration membranes. Its structure is similar to curtain and consists of multiple ultrafiltration membranes. The membranes are fixed by a supporting structure to form a parallel flow channel system. It is usually used in sewage treatment, drinking water purification, industrial water reuse etc.

    II. What are the characteristics of curtain-type ultrafiltration membrane assembly?　　

● Super strong chemical properties

It can be used for high-salt, high-alkali, high-acid, organic solvent wastewater and special separation. It has no pH value limit and is stable to general acids, bases, salts, aromatic aliphatic hydrocarbons, etc. except strong solvents, concentrated nitric acid and sulfuric acid.

● High mechanical strength

The membrane filament has the best bending and mechanical strength, extremely high toughness, and outstanding resistance to stress cracking. It is made of PVDF or modified PPSU and is manufactured by adopting the special wire drawing method independently developed by Shangshui Hengmo, so it has high mechanical strength. Under normal operating conditions, the membrane assembly can ensure high integrity and durability.

● Anti-pollution

The membrane is made of PVDF or PPSU materials with strong chemical resistance, excellent long-term hydrolysis stability, and can withstand high concentrations of sodium hypochlorite and acid. It can maintain long-term membrane filtration flux through effective chemical cleaning. Its tolerance can reach 8000ppm and can be sterilized at high temperature for a long time.

● Stable filtration flux

The membrane is made by adopting special wire drawing method and has high water permeability and extremely strong anti-fouling and clogging ability. It can provide high filtration flux and stable operation for different water sources.

● Good product water quality

It can provide the best filtered water quality, maintain extremely low treated water turbidity and very high pathogenic microorganism removal rate (6log). The membrane has a molecular weight cutoff of 50,000 Daltons and has very high retention performance sensitivity or very narrow pore size distribution range, which is suitable for removing bacteria and pathogenic microorganisms such as Cryptosporidium. It can effectively intercept large molecular organic matter to make biochemical efficiency higher.

    III. What are the application fields of curtain-type ultrafiltration membrane assembly?

The curtain-type ultrafiltration membrane assembly of Shangchen Environmental has high-efficiency filtration performance and large flux, and is suitable for large-scale water treatment applications.

1. Treatment of municipal sewage: It is especially suitable for areas with high water quality requirements and limited land use.

2. Treatment of industrial wastewater: Such as textile printing and dyeing, food processing, pharmaceutical and other industries.　

3. Reuse of recycled water: The quality of treated water can meet the reuse standards, realizing the recycling of water resources.

4. Treatment of small-scale decentralized sewage: It is suitable for rural areas, scenic spots and other areas.

5. Treatment of drinking water: It can remove bacteria, viruses and suspended matter in water to ensure drinking water safety.

6. Treatment of sewage: It is used for deep treatment of urban sewage and industrial wastewater to help achieve water reuse.

7. Treatment of seawater before desalination: It is used to remove large particles and suspended matter in seawater and protect subsequent reverse osmosis systems

    IV. How to maintain the curtain-type ultrafiltration membrane assembly?

1. Regular cleaning: Maintain membrane performance through chemical cleaning or physical cleaning.
2. Optimize the operating parameters: Adjust parameters such as membrane flux and aeration volume according to the influent characteristics.
3. Monitor key indicators: Monitor the transmembrane pressure difference, pH value, dissolved oxygen etc. in real time.
4. Prevent membrane pollution: Do well in pretreatment and control the quality of incoming water.
