EenheidstruktuurWysig

Die eenheid doen navorsing oor kruisdissiplinêre waterkwessies wat verband hou met die nywerheid en mynbou. Die groep bestaan uit deskundiges in chemiese ingenieurswese, mikrobiologie en ander wetenskappe.

  • Industriële biotegnologie – die gebruik van biotegnologie in waterverwante toepassings, bv. vir watersuiwering en watervermindering.
  • Bedryfsekologie – die gebruik van volhoubaarheidsbeginsels om die impak op die omgewing te verminder; veral met betrekking tot water.[36][37]
  • Lewensiklusassessering (LSA/LCA) – kwantifisering en minimalisering van vloeibare, vaste of gasagtige afval op terreine wat voedselverwerking, industriële bioverwerking en ander insluit.[38][39][40][41][42][43][44][45]
  • Membraantegnologie
  • Nanotegnologie
  • Osoon – bepaling van optimale behandelingstegnieke vir koelwater-suiweringstelsels, chemies teenoor osoon.
