J. (Hans) van Leeuwen is a professor of Civil, Construction and Environmental Engineering at Iowa State University.

Biography

He was born Johannes van Leeuwen, in 1946 in Gouda, Netherlands. He lived in the Netherlands, South Africa, Australia and has been residing in the United States since 2000. He is currently working as a professor in the Department of Civil, Construction and Environmental Engineering [[1]] at Iowa State University [[2]] in Ames, Iowa. Together with Balaji Narasimhan, he was given a Vlasta Klima Balloun Professorship [[3]] at Iowa State University.[1]

Education

  • University of Pretoria (South Africa), 1988 - D Eng, environmental engineering [[4]]
  • University of Pretoria, 1983 Graduate Diploma of Tertiary Education
  • University of Pretoria, 1979 - MS, engineering, water utilization
  • University of Pretoria, 1975 BS, chemical engineering.

Research

His research includes the recovery of byproducts from liquid wastes and sludges, fungal treatment of food processing wastewater, and reuse applications of residues from water softening. He has several patents to his name. He has developed processes for purifying alcohol, creating a new product at ethanol plants, and keeping exotic species out of coastal waters through disinfestation of ballast water with bromine production through ozonation. The purification of alcohol makes the world's purest vodka possible and Oz Spirits LLC, of which he is the founder, is launching a product based on this process involving ozone, activated carbon, and nanogold filtration. He developed a new animal feed, potentially a new human food source, by developing a process for cultivating fungi on corn processing leftovers, with a product, MycoMeal, being commercialized through MycoInnovations. His ozonation process disinfestates ships' ballast waters of feral species to avoid introduction into coastal waters by shipping and has been applied on oil tankers.
