Membrane Technology
Altiras Labs is leading membrane research in the application of various membrane technologies to real-world chemical recycling needs. We’ve expanded our capabilities to include various membrane technologies, enhancing our portfolio of separation and purification solutions. This move not only underscores our dedication to addressing industrial challenges but also cements our position in the field of chemical process research and development.
ADVANCED SEPARATION SOLUTIONS
Altiras Labs works with ceramic and polymeric composite membranes in various processes including reverse osmosis, nano-filtration, ultra-filtration, micro-filtration, pervaporation, membrane distillation, and more. We perform testing on small flat-sheet units up to larger scale testing that can range from permeate rates of 50 ml/hr to 1900 L/hr. We can test utilizing almost any commercially available membrane and can also custom treat membranes and membrane surfaces to meet our clients’ needs.

EQUIPMENT AND TEST CAPABILITIES
Altiras Labs has invested heavily in membrane equipment and technology to provide timely and effective testing of membranes in different operating environments. We currently have the following Test Equipment.
Lab Scale Flat Sheet (High-Pressure Unit)
Designed for low or high-pressure applications, this stainless steel unit supports initial testing in small-scale studies with a surface area of about 266 square centimeters. It tests up to 50 bar (725 psi) and offers a Hastelloy C276 option for strong acids. Primarily, it screens reverse osmosis, nanofiltration, and ultra-filtration membranes.
Rigid Zeolite / Ceramic Unit
This unit handles liquid phase tangential flow (TFF), pervaporation, and vapor permeation. Applications include solvent dehydration, water azeotrope breaking, metal removal, and other applications requiring robust and durable membrane materials. The unit is stainless steel and generally operates at pressures below 100 psi.
Low-Pressure Tangential Flow Unit
This stainless steel unit handles lower-pressure applications, evaluating sustained conditions for membranes in gentler environments, including biological separations.
Spiral Wound 2540 Unit
Designed for size 2540 membranes, this unit handles high and low-pressure reverse osmosis, nano-filtration, and ultra-filtration. It operates at pressures up to 1000 psi, accommodating testing of tote-size quantities.
