CM 500D Product Parameters
The CM 500D ultrafiltration hollow fiber reinforced membrane provides customers with high-performance energy efficiency and proven membrane life.
The CM 500D membrane gives customers the flexibility to treat any flow rate from ultra-low flows to mega MBR plants .
CM 500D MBR membrane is a high performance, energy efficient solution that is a perfect replacement for Zeeweed 500D. Echoing the capabilities of Zeeweed 500D, our membranes offer longer life and the flexibility to handle any flow rate from ultra-low flows. Larger MBR plants have lower flow rates. Its excellent flux rate makes it an excellent choice for high-flow applications, and its chemical resistance ensures its suitability in domestic and industrial wastewater treatment scenarios. Choose CM 500D MBR membranes for a reliable, efficient and cost-effective upgrade to your water treatment system.

Our Happy Clients From 30+ Countries
I have been working with CM for 3 years and I am glad that I chose them from the beginning. Their product quality is very high and my customers have never complained about their products. Shanghai Chenmo, as a professional manufacturer, has always provided us with professional technical support. At the same time, they also responded to all our technical issues in a timely manner, ensuring that my customers can get the equipment running smoothly.
Abdulla Bal
From Kazakhstan
We met at the Shanghai Water Treatment Exhibition. My colleagues and I visited their factory in person and were impressed by their advanced equipment. As a replacement project, the 500D membrane module provided by Shanghai Chenmo ran perfectly in the original system, which was great.
Giovamny Bernard
From ominican
During the entire purchase process, CM made me feel very safe. Their sales staff were very professional. Thank you for providing me with a design plan, which enabled our sewage treatment plant project to be implemented quickly. Now the entire sewage treatment plant project is running stably, and everything looks very good.

500D Production Process
We have 3 production lines, each of which can produce 3,000 square meters of membrane modules per day, and the 3 production lines can simultaneously batch produce membrane modules of different specifications to achieve rapid delivery capabilities.
PVDF Raw Materials
The PVDF raw material has been repeatedly tested and has excellent hydrophilicity.
Using Advanced NIPS Technology
Ensure uniform film texture, stable performance and high tensile strength
Hollow fiber drying
The drying process helps to stabilize the membrane pore structure, making the membrane’s filtration performance more precise, making the material’s internal structure more stable, and enhancing its mechanical strength.
Batch Glue Filling
In a constant temperature and humidity environment, batch filling helps to ensure stable and consistent product quality
Production Completed
The 500D membrane modules that have been produced are protected with transparent films and are waiting to be packed.
500D Membrane Module Frame
- Highest solids tolerance of any hollow-fiber membrane
- Works through virtually any raw water quality change or upset
- Outside-in flow path provides a more robust system
- Fully automated for simplified design and operation
- Outstanding technology for virtually all wastewater treatment applications – from greenfield plants to retrofits to water reclamation projects
Package & Shipping
- Each piece membrane is protected by foam
- Both ends are fixed to reduce collisions during transportation
- Sturdy wooden box protects every piece membrane
- Each box has a quality inspection certificate
FAQs About CM 500D Membrane
