Lab Scale systems
Lab scale testing at our customers’ facilities permits us to show our customers that we can help them achieve their filtration as well as valuable liquid and solid recovery goals.
Pilot Scale Systems
After successful lab scale testing, most projects go through pilot scale testings on-site to ensure compatibility with actual process conditions. Our pilot units are typically connected directly to the client’s filtration process.
