Successful application of PVP in reverse osmosis membrane: case study of Vietnamese water treatment customer

Vietnam is a fast-growing market, especially in the water treatment industry, where demand is increasing. A leading local water treatment company, focusing on industrial and civil water treatment solutions, faced the challenge of insufficient membrane material performance. In order to improve water treatment efficiency and membrane life, the company decided to seek a high-performance membrane material and finally chose polyvinyl pyrrolidone (PVP).

Cooperation process

In the cooperation with East Chemical, the Vietnamese customer first conducted sample testing. By evaluating the physical and chemical properties of polyvinyl pyrrolidone, the customer found that the material performed well in the hydrophilicity, chemical stability and anti-fouling properties of the membrane. After a series of experiments, the customer decided to apply polyvinyl pyrrolidone to the production of its reverse osmosis membrane and nanofiltration membrane.

Results and feedback

After several months of testing and trial production, the performance of the customer's water treatment membrane products has been significantly improved. Specifically:

Increased water flux: The membrane using polyvinyl pyrrolidone has a 20% increase in water flux compared to traditional membranes.

Enhanced anti-fouling ability: The anti-fouling performance of the membrane has been significantly improved, which has extended the cleaning cycle and reduced maintenance costs.

Extended service life: The service life of the membrane is extended by 30%, effectively reducing the replacement frequency.

The customer highly praised the performance of polyvinyl pyrrolidone and believed that its application in the field of water treatment membranes has significantly improved the company's product competitiveness.

Advantages of East Chemical Polyvinyl Pyrrolidone

East Chemical's polyvinyl pyrrolidone not only has excellent hydrophilicity and chemical stability, but also effectively enhances the membrane's anti-pollution ability and service life. Its high purity and stability make it an ideal choice for the water treatment industry and can meet the needs of various water quality treatments. In addition, East Chemical also provides professional technical support to help customers optimize the membrane production process and achieve higher production efficiency.

Through this successful case, the experience of Vietnamese customers shows that choosing the right membrane material is crucial to improving water treatment efficiency, and polyvinyl pyrrolidone is undoubtedly a high-quality choice in this field.
