Damage to RO Membranes by the Overuse of Ion-Exchange Resin Cleaning Chemicals in Pretreatment Softeners
By Timothy J. Miller
In October 2005, Purdue University opened the Birck Nanotechnology Center (BNC). Providing office space for 45 faculty and 220 graduate students, 22,000 square feet of laboratory space, and 25,000 square feet of clean room space the facility is one of the largest of its type in the United States. Features like an integrated Bio-Clean room, ultra-quiet metrology laboratories, and the Type E1.2 high-purity water system make the BNC unique among its peers. The research being carried out at Birck includes projects on traditional silicon semiconductor electronics, silicon carbide high temperature/high power thyristors, MEMS devices capable of counting the numbers of bacteria of a particular strain in solution, and negative refractive index of materials that may someday provide optical invisibility. These are but a few of the research projects at the BNC.
