Vibratory shear enhanced process (VSEP) is a membrane separation technology platform invented in 1987 and patented in 1989 by Dr. J. Brad Culkin.〔http://patft.uspto.gov/netacgi/nph-Parser?Sect2=PTO1&Sect2=HITOFF&p=1&u=/netahtml/PTO/search-bool.html&r=1&f=G&l=50&d=PALL&RefSrch=yes&Query=PN/4952317〕 VSEP’s vibration system was designed to prevent membrane fouling, or the build-up of solid particles on the surface of the membrane. VSEP systems have been applied in a variety of industrial environments.〔http://www.vsep.com/technology/applications.html〕 == History and technology development == After earning his PhD in chemical engineering from Northwestern University.〔http://www.waterandwastewater.com/www_services/ask_tom_archive/concentrating_ro_reject_streams_with_vsep.htm〕 Dr. Culkin spent his early professional career with Dorr–Oliver, Inc., a pioneering company in the area of separations.〔http://www.vsep.com/technology/faq.html〕 Culkin contributed to six Dorr–Oliver patent applications in 1985 and 1986.〔http://www.patentbuddy.com/Inventor/Culkin/Joseph/B/10336103〕 While at Dorr–Oliver, Dr. Culkin was exposed to the advantages of membrane separation technology as well as its failings. The membrane’s Achilles Heel, Culkin decided, was fouling.〔http://www.vsep.com/technology/index.html〕 Concurrent with his membrane work, Culkin was helping to develop a mechanically resonating loudspeaker with the founders of Velodyne Acoustics.〔http://www.velodyne.com/news/INDUSTRY%20GIANTS%20%282%29.pdf〕 Culkin married these two areas of expertise and struck out to overcome membrane fouling though the use of vibration. The first VSEP prototype Culkin developed was a literal combination of loudspeaker and membrane technology 〔http://www.vsep.com/technology/faq.html#1〕 as the photo shows below.
