  3. 2. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Amrith Kumar; [2022]
    Keywords : Coagulation; flocculation; jar test; microplastics; sedimentation; water treatment; Burktest; flockning; koagulering; mikroplaster; sedimentering; vattenrening;

    Abstract : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.

  4. 3. Analysis of Benzoisothiazolinone in process water from operations that handle large amounts of paint residues

    University essay from KTH/Kemi

    Author : Cagenna Magendran; [2022]
    Keywords : Flocculation; Gas chromatography-mass spectrometry; Isothiazolinones; Paint residues; Stockholm s water and waste; Flockulering; Gaskromatografi-masspektrometri; Isotiazolinoner; Färg rester; Stockholm vatten och avfall.;

    Abstract : I denna studie undersöks isotiazolinoner i avloppsvatten eftersom det finns i alla kommersiella färger. För att avgöra om reningsverken är tillräcklig bra används gaskromatografi-masspektrometri (GC-MS) för att analysera förekomsten av BIT i processvatten som släpps ut i mjövattnet. READ MORE

  5. 4. Treatment of dissolved metals in highway runoff water : Pilot-scale trial with four reactive filter media and sand filter

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Keywords : stormwater treatment; metal removal; adsorption; reactive filter media; sand filtration; Petrit-T; Polonite; D-Rainclean; Filtralite-P; de-icing salt; pressure drop; filter clogging; rening av dagvatten; avl ̈agsnande av metaller; adsorption; reaktiva filterme- dier; sandfiltrering; Petrit-T; Polonite; D-Rainclean; Filtralite-P; avisningssalt; tryckfall; filterstoppning;

    Abstract : The increasing highway traffic is leading to higher and higher levels of pollutants in the stormwater, such as suspended solids, metals, oils, nutrients and PAH. This runoff water causes the degradation of water bodies quality, leading to increased interest in the treatment of highway runoff for the removal of contaminants. READ MORE

  6. 5. Mapping of Bacteria with Flow Cytometry – before, during and after treatment of drinking water

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Mikael Danielsson; [2018]
    Keywords : Biology and Life Sciences;

    Abstract : In order to produce drinking water of high quality, surface water works apply extensive treatment processes. In this study, flow cytometry and heterotrophic plate counting was utilized to study water quality before, during and after treatment in Görvälnverket in Stockholm, Sweden. READ MORE
