We’ve been noticing a surge in technical inquiries from around the globe regarding our NAGASEP hollow fiber membrane modules. One topic stands out: energy-saving solutions for wastewater treatment.
Today, we want to share a specific case from a customer in India that highlights the unique potential of NAGASEP.
The Challenge: 5% IPA in Wastewater
Our client in India reached out with a specific problem. They had wastewater containing oil and about 5% Isopropyl Alcohol (IPA). Their question was simple: “Can NAGASEP handle this and help us recover the solvent?”
The Solution: NAGASEP’s Selective Separation
The short answer? Yes. Depending on the specific conditions, NAGASEP hollow fiber membranes can be adapted to separate and recover organic solvents from water.
To determine the feasibility and the exact scale of the system (number of modules and configuration), we typically look at three key factors:
Flow Rate: How much wastewater needs processing?
Concentration: What is the exact solvent percentage?
Operating Conditions: What are the temperature and pressure levels?
Let’s Start Testing
If you provide us with these details, we can calculate the potential scale and feasibility for your specific needs. We’re always ready to support you—starting from small-scale lab tests to evaluate the performance before moving to full implementation.
