The Equilibar® back pressure regulator is being used by the Chemical Engineering Department at the University of Texas at Austin to study membrane fouling in applications such as industrial water purification.
The stainless steel regulators are being used together with the Equilibar QPV electronic pilot regulator to create a high precision low pressure control for both the membrane upstream and downstream pressure conditions.
The research is featured in the American Institute of Physics’ Review of Scientific Instruments, in a paper entitled ” A crossflow filtration system for constant permeate flux membrane fouling characterization”.
Many industrial and research clients use the QPV together with the Equilibar® back pressure regulator because both devices have sensitive, hysteresis-free performance. This UT Austin application used LabView to command the QPV, creating a high-performance automated pressure control system for their experiments.
