1. Energieffektivisering av membranluftrengöring vid högflödesperioder : Studie på en storskalig MBR-pilot på Syvab Himmerfjärdsverket i samarbete med SUEZ Water Technologies and Solutions
Master-uppsats, Karlstads universitetSammanfattning : Membrane BioReactor (MBR) is a wastewater treatment method which combine both biological and physical cleaning. In the membrane tank there is membrane fibres which physically separate wastewater from containing organic material. This causes the membrane fibres to easily build fouling. LÄS MER
2. Ultrafiltration of Bleach Plant Efflunet from a Sulphite Pulp Mill-Influence of operating parameters
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Stora Enso Nymölla Mill is an integrated pulp and paper mill located in south Sweden near the Baltic Sea. The mill uses ultrafiltration (UF) to remove compounds with a high chemical oxygen demand (COD) from the bleach plant effluent. UF is a separation technology using membranes. LÄS MER
3. Nanofiltration of ultrafiltration permeate fom chemical wastewater
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The aim of this report was to investigate the possibility of further cleaning of the wastewater at Dow in Landskrona. Dow produces water based adhesives from acrylic monomers. The wastewater contains different metal ions, surfactants, residual monomers and polymers. LÄS MER
4. Influence of gas sparging on membrane performance
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : A new oxygen barrier film that is made of arabinoxylan has been developed by the company Xylophane. Arabinoxylan is available among other things in wheat bran. But a problem with the method of extracting the arabinoxylan is that after an alkali extraction is ultrafiltration used to remove impurities and the flux during this is quite low. LÄS MER
