    Author : Sofia Mile; [2023]
    Keywords : Chemical Engineering; Water and Environmental Engineering; Water Treatment; Coagulation Flocculation; Sludge Recirculation; Technology and Engineering;

    Abstract : Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g. READ MORE

  3. 2. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Bhargav Reddy Elavarthi; [2021]
    Keywords : micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Abstract : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. READ MORE

  4. 3. Evaluation of sustainability criteria for small-scale wastewater treatment facilities

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Edvard Nordenskjöld; [2017]
    Keywords : On-site sewage facilities; phosphorus; micropollutants; multi-criteria analysis; precipitation; adsorption; full-scale; wastewater treatment; Enskilda avlopp; fosfor; mikroföroreningar; multi-kriterie analys; utfällning; adsorption; fullskala; avloppsrening;

    Abstract : There are about 700,000 on-site sewage facilities (OSSFs) in Sweden, almost a quarter of which amount only to septic tanks for sludge collection and removal, with no form of post-treatment. All these OSSFs contribute about 10 % of the total anthropogenic phosphorus (P) load from Swedish coasts to the Baltic Sea. READ MORE

  5. 4. Integration of powdered activated carbon in tertiary disc filtration of wastewater

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Elias Thörnqvist; Philip Isgaard; [2016]
    Keywords : vattenförsörjningsteknik; water engineering; environmental engineering; flocculation; coagulation; PAC; disc filter; micropollutants; powdered activated carbon; avloppsteknik; Technology and Engineering;

    Abstract : This thesis investigates the feasibility of integrating Powdered Activated Carbon (PAC) in to chemical treatment in combination with disc filtration of tertiary wastewater. Jar and tube tests have been performed, where the suspension was filtered through a 10 μm disc filter from Hydrotech Veolia Water Technologies. READ MORE

  6. 5. Development of an Expancel Product through Optimisation of Polymer Composition and the Suspension Stabilising System

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Frida Berggren; [2014]
    Keywords : microspheres; suspension polymerisation; Pickering emulsions; flocculation;

    Abstract : Thermally expandable microspheres are spherical particles around 5-­‐40 µm in size, consisting of a polymeric shell in which a blowing agent has been encapsulated. The microspheres are expanded upon heating, resulting in a particularly low density. Microspheres are therefore suitable to use as light weight filler or as foaming agent. READ MORE
