6. Enzymatic treatment of wastewater sludge. Sludge solubilisation, improvement of anaerobic digestion and extraction of extracellular polymeric substances
Sammanfattning : The processing and disposal of sludge from wastewater treatment plants is an important topic of increasing environmental, ecological, technological, economic and social concern. The large amounts of sludge produced represent an urgent problem today, new treatment methods being very much needed. LÄS MER
7. Transport of Heavy Metals in Soil Subjected to an Electric Field -A Study of the Transport of Copper in Bentonite Clay
Sammanfattning : This licentiate thesis addressesphosphorus release from sewage sludge, which is the first stepin phosphorus recovery. The concept ofphosphorus recovery maybe seen as a part of sustainable sludge handling in that it isa means of recycling resources without supplying harmfulsubstances to humans or the environment.

8. Flocculation with Polyelectrolytes in Latex and Microbial Systems
Sammanfattning : Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. LÄS MER
9. Physicochemical Treatment of Municipal Wastewater : From Direct Membrane Filtration to Adsorption of Organic Micropollutants
Sammanfattning : Pharmaceutical residues and other organic micropollutants are transported via municipal wastewater to wastewater treatment plants (WWTPs). However, current treatment processes are not designed to remove organic micropollutants, and several such compounds have been found in recipients, where they can have negative effects on aquatic organisms.

10. Extending Wastewater Treatment Process Models for Phosphorus Removal and Recovery : A Framework for Plant-Wide Modelling of Phosphorus, Sulfur and Iron
Sammanfattning : As problems associated with shortage in resource supply arise, wastewater treatment plants turn to innovation to transform themselves into resource recovery facilities. Water groups worldwide recognize that wastewater treatment plants are no longer disposal facilities but rather sources of clean water, energy and nutrients. LÄS MER
