Glossary of membrane testing and performance terms including flux, rejection, MWCO, SDI, TMP, permeability, crossflow test cells, coupon testing, and membrane characterisation techniques.

One of the most frustrating experiences in membrane research is discovering that your laboratory results don't translate predictably to pilot scale. A membrane that showed excellent performance in a 100 cm² flat sheet cell suddenly exhibits unexpected fouling in a pilot module. Flux targets that were easily achieved in the lab require 20% higher pressure at pilot scale. Recovery rates that looked promising in batch testing prove incompatible with continuous operation. These

The difference between a good membrane research program and an excellent one often comes down to data quality and quantity. Manual data collection—jotting down pressure readings every five minutes, recording temperature changes on paper, manually calculating flux rates—is slow, error-prone, and fundamentally incompatible with modern research standards. Tech Inc.'s integrated digital data acquisition (DAQ) systems transform membrane testing from a manual, labor-intensive proc

Membrane geometry is a fundamental design decision that shapes every aspect of your research program. Whether you choose flat sheet or hollow fiber membranes determines not only the physical setup of your test cell but also your testing flexibility, achievable flux rates, scalability pathway, and ultimately the applicability of your lab results to commercial systems. Tech Inc., with over a decade of experience delivering membrane test cells to researchers worldwide and appro

Temperature is one of the most critical operating parameters in membrane separation research. From membrane distillation applications that require precise thermal control to pervaporation processes that demand consistent heating, the ability to accurately test membranes under elevated temperatures is essential for developing robust industrial solutions.

Dead-end (also called stirred cell or batch) membrane test cells represent a distinct and complementary approach to membrane evaluation, offering rapid, economical assessment of membrane properties and performance. In sharp contrast to the extended, continuous operation of crossflow systems, dead-end cells enable screening-level evaluation using minimal feed volume, making them ideal for early-stage research, membrane material comparison, and specific characterization tests t

Crossflow—also known as tangential flow or parallel flow filtration—represents a fundamental advancement in membrane separation technology. Unlike dead-end (perpendicular) filtration where all feed flows directly into the membrane, crossflow introduces feed parallel to the membrane surface, creating shear forces that minimize fouling, extend membrane life, and dramatically improve process economics.

Low-pressure membrane filtration technologies—including microfiltration (MF) and ultrafiltration (UF)—form the foundation of modern water and wastewater treatment, food and beverage processing, pharmaceutical manufacturing, and countless industrial separation applications. The ability to evaluate MF and UF membranes under controlled laboratory and pilot-scale conditions is essential for membrane selection, process optimization, and pretreatment validation.

High-pressure membrane test cells represent a critical foundation for developing and validating reverse osmosis (RO), nanofiltration (NF), and high-pressure reverse osmosis (HPRO) technologies. Whether you're working on desalination solutions, industrial water treatment, or cutting-edge membrane material development, the ability to test membranes under controlled, repeatable high-pressure conditions is essential.
