  1. 6. Biofouling on plate heat exchangers and the impact of advanced oxidizing technology and ultrasound

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Anna Hjalmars; [2014]
    Keywords : Ultrasound; Biofilm; AOT; Plate Heat Exchangers and Crystal Violet;

    Abstract : Fouling in general and biofouling in specific is a problem concerning many industries. Biofouling occur in environments favorable for biological growth. As an example, industries using cooling water have problems with biofouling. The problem is apparent on heat exchangers as biofilm reduces the heat transfer and thus the performance. READ MORE

  3. 7. Comparison of UV-C and Vacuum- UV induced AOT on the acute mortality of microalgae.

    University essay from KTH/Mark- och vattenteknik

    Author : Eric McGivney; [2013]
    Keywords : Advanced oxidation technology; vacuum UV; UV-C; titanium dioxide; algae; Pseudokirchneriella subcapitata; Tetraselmis suecica; ballast water treatment;

    Abstract : Advanced oxidation technology (AOT) has been used to destroy microorganisms in ballast water by breaking down the cell membranes. The primary objective of this study was to determine the effects of a ballast water treatment system that uses a combination of UV-C (λ=254 nm), Vacuum-UV (VUV; λ=185 nm) and photocatalytic titanium dioxide (TiO2) on a freshwater algae, Pseudokirchneriella subcapitata, and a marine algae, Tetraselmis suecica.

    Abstract : Irrigation with untreated or low quality water often disperses many infectious diseases. In Sweden, 90 to 99.9% reduction of microorganisms in the water can be achieved by waste water treatment but potential risk of high number of sewage, substantial loads of pathogens could still remain.
