Colloidal Wood Resin: Analyses and Interactions
(Dr. ingeniøravhandling, 0809-103X; 2003:63, Doctoral thesis, 2003)This thesis presents studies of the interactions between suspended particles and dissolved and colloidal substances (DCS) in process water. The main focus has been to determine if colloidal wood resin is adsorbed by suspended ... -
Ultrafiltration of Partially Degraded Starch Solution
(Dr.ingeniøravhandling, 0809-103X; 2002:87, Doctoral thesis, 2002)Desizing wastewater is largely responsible for the chemical oxygen demand (COD) load in the textile industry wastewater. A larger portion of COD comes from degraded starch in desizing wastewater. Removing the starch from ... -
Non-Intrusive Mass Flow Measurement of Solids in Pneumatic Conveying Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:76, Doctoral thesis, 2011)Measuring mass flow of solids in pneumatic conveying systems has been a key element in industry and a challenge for researchers for many years. Many methods have been developed in the past; however, there is no perfect ... -
Flow and Heat Transfer in a Radially Spreading Liquid Metal Jet Related to Casting of Ferroalloys
(Dr. ingeniøravhandling, 0809-103X; 2000:83, Doctoral thesis, 2000)In the past more and more advanced and fine-tuned processes for steel production have resulted in increased demands for new and more costeffective ferroalloys used as constituents in the processes. Casting techniques and ... -
