  1. 1. Automation of a rotating bed reactor for PFAS remediation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Axel Martin; [2023]
    Keywords : Programming; automation; experimentation; optimization;

    Abstract : Properties such as being water and oil repellent and being heat resistant make per- and polyflouroalkyl substances (PFAS) useful in a wide range of products. Since they do not break down in the environment, PFAS pollution makes it way back into drinking water and seafood. READ MORE

  3. 2. Analysis of Methanol Based Chlorine Dioxide Production : An analysis of sodium chlorate reduction efficiency and investigation of salt cake filter wash on an SVP-LITE® system

    University essay from Karlstads universitet

    Author : Emil Lundh; [2023]
    Keywords : ECF; SVP-LITE®; chlorine dioxide; bleaching; ECF; SVP-LITE®; Klordioxid; blekning;

    Abstract : This work aimed to determine how effective an SVP-LITE® chlorine dioxide plant at Vallviks Bruk was running. This was done by determining the chemical consumption per unit of chlorine dioxide produced. The calculations relied upon online instrumentation that was manually validated. READ MORE

  4. 3. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Shea Nee Chew; [2023]
    Keywords : Moving bed biofilm reactors; Biofilm carriers; Mechanical mixing; Mixer configurations; Carrier mixing; Biofilmsreaktorer med rörlig bädd; Biofilmsbärare; Mekanisk blandning; Blandarkonfigurationer; Bärarblandning;

    Abstract : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. READ MORE

  5. 4. Electrosynthesis of persulfate and hydrogen gas with boron doped diamond as the anode material

    University essay from KTH/Kemiteknik

    Author : Sandra Shneker; Tsion Abebaw Kebede; Vera Lindbäck; [2022]
    Keywords : Boron-doped diamond; persulfate; flow cell; electrosynthesis; current efficiency;

    Abstract : The efficiency of boron-doped diamond electrodes (BDD) has been investigated by electrolysis of an aqueous solution containing sodium sulfate. A Synthesis StarterKit from Condias was used, which contained the BDD anode with an active surface area of 3.14 cm2, and electrosynthesis was performed in a batch mode reactor. READ MORE

  6. 5. Numerical Design of an Extremely High Temperature Thermochemical Reactor for Converting Biochar to Hard Carbon

    University essay from KTH/Kraft- och värmeteknologi

    Author : Jinghe Zhang; [2022]
    Keywords : CFD; Hard carbon; Biochar; Induction heating; Energy efficiency; CFD; Hårt kol; Biokol; Induktionsuppvärmning; Energieffektivitet;

    Abstract : Hard carbon is now a popular choice for the anode material in sodium-ion batteries. Converting biochar to produce hard carbon is considered carbon neutral and of great interest since it reduces the environmental impacts of biomass waste. READ MORE
