  1. 1. Mainstream Deammonification process monitoring by bacterial activity tests

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Andrea Carranza Muñoz; [2020]
    Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

    Abstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE

  2. 2. The Role of Independent Financial Advisors in the IPO Process

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Julian Kasturiarachchige; Janis von Zimmermann; [2019]
    Keywords : Financial Advisor; Initial Public Offering; Underpricing; Asymmetric Information;

    Abstract : The European Initial Public Offering (IPO) market has seen an important innovation within the last decade: the increasing participation of Independent Financial Advisors (IFA) in the IPO process. Using data from 373 Western European IPOs between January 2012 and February 2019, this paper applies a multivariate regression model to examine the potential impact of IFAs on IPO underpricing, a phenomenon that refers to the persistence of significant, positive initial returns for shares issued in an IPO.

  3. 3. Anammox in IFAS reactor for reject water treatment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Bingquan Chen; [2019]
    Keywords : Deammonification; IFAS; Online sensors; Partial nitritation Anammox; Reject water; Specific anammox activity;

    Abstract : The aim of this study was to evaluate the performance of the integrated fixed-film activated sludge (IFAS) reactor achieving partial nitritation/anammox process to treat reject water after dewatering of digested sludge. During the study period, dissolved oxygen setpoint, aeration mode and inflow loading were changed to evaluate their influence on the process performance and efficiency in the reactor. READ MORE

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Karolina Los; [2018]
    Keywords : Wastewater; Nitrogen removal; Deammonification; Partial Nitritation; Anammox; Mainstream;

    Abstract : .... READ MORE

  5. 5. Nitrogen removal from municipal wastewater by mainstream Partial Nitritation/Anammox process

    University essay from KTH/Vatten- och miljöteknik

    Author : Alessio Robiglio; [2018]
    Keywords : Mainstream; Deammonification; IFAS; UASB; Anammox; Anoxia; Aeration; Online; Monitoring; Inhibition; Wastewater;

    Abstract : Mainstream Partial Nitritation/Anammox, also known as Mainstream Deammonification, is a promising technology for future wastewater purification that aims to remove nitrogen from wastewater in order to prevent the eutrophication. It is less costly than the traditional nitrification/denitrification process and it heads towards the direction of converting the WWTPs from energy consuming into energy producing facilities.
