Industrial Ultrafiltration

Is Your Plant’s Ultrafiltration Foulant Free?

Producers of industrial ultrafiltration systems often show customers a clear, clean liquid after a brief test running the customer’s industrial fluid through an ultrafiltration membrane. However, the reality of continuously running ultrafiltration (UF) with known membrane foulants such as oils, polymers, coatings, and blinding particulates in your industrial fluids is undoubtedly more complicated.

Let’s take the case of UF filtration for industrial wastewater. Customers regularly tell us:

• My permeate flow rate drops very quickly, resulting in frequent backwashes and CIPs (clean-in-place cycles).
• My membrane efficiency drops significantly over time despite the constant backwashes and CIPs, resulting in less permeate flow.
• I must frequently dump my ultrafiltration concentration tank, often causing significant UF downtime.
• My current ultrafiltration continuously fouls, and I cannot keep up with my plant’s waste stream. I worry that my production will stop.
