  1. 1. Considerations and Novel Technologies in Industrial Water Treatment - Treatment of challenging wastewater

    University essay from KTH/Kemiteknik

    Author : Nils Toll; [2021]
    Keywords : Industrial water treatment; considerations; novel technologies; BOD; COD; organic waste; heavy metals; desalination; Industriell vattenrening; nyckelfaktorer; nya teknologier; organiskt avfall; tungmetaller; avsaltning;

    Abstract : Industriell vattenrening är ett extremt viktigt område inom Miljöskyddsteknik då 60% av allt sötvatten inom Sverige används av industrier. Substanser som PFAS, aromatiska textilfärger, fenol och läkemedelsrester är extra utmanande då dessa kan vara gifta för biologisk rening. READ MORE

  3. 2. Monovalent selective electrodialysis in greenhouses - An analysis of brackish groundwater and greenhouse wastewater treatment

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Georg Schücking; [2020]
    Keywords : desalination; water treatment; greenhouses; ED; MSED; monovalent selective electrodialysis; groundwater; sodium; nitrate; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Abstract : Water use in greenhouse can be optimized by switching to alternative sources of irrigation water and building zero-liquid discharge systems that recirculate greenhouse effluent. The use of brackish groundwater (BGW) has become a popular option for greenhouses that have adopted reverse osmosis (RO) to reduce the salinity of their source water. READ MORE

  4. 3. Electrodialytic Remediation of PFAS-Contaminated Soil

    University essay from KTH/Vatten- och miljöteknik

    Author : Georgios Niarchos; [2018]
    Keywords : Per- and polyfluoroalkyl substances; Electrokinetic; Ground; Groundwater; Treatment; Electrochemistry; Environment; Per- och polyfluoralkylsubstanser; Electrokinetisk; Grundvatten; Förorening; Elektrokemi; Miljö;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of anthropogenic aliphatic compounds, widelyknown for their environmental persistence and toxicity to living beings. While they are ubiquitous in theenvironment, interest has been focused on contaminated soil, which can act as a primary recipient andsource of groundwater contamination. READ MORE

  5. 4. Characterization of Succinate Producing Bacteria

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sofia Nyström; [2015]
    Keywords : xylose; succinic acid; chemical engineering; kemiteknik; biological production; Chemistry;

    Abstract : Målet med detta projekt var att studera två sorters bakterier, Actinobacillus succinogenes och Basfia succiniciproducens, och deras produktion av bärnstenssyra. Bärnstenssyra är en dikarboxylsyra som även är en metabolit i citronsyracykeln. READ MORE

  6. 5. Split of sodium and sulfur in a Kraft mill and internal production of sulfuric acid and sodium hydroxide

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Helena Lundblad; [2012]
    Keywords : LignoBoost; electrodialysis; salt split; bipolar membrane; internal production;

    Abstract : The removal of lignin in a Kraft pulp mill, with the aim to utilize the lignin as more value added green product than just firing lignin in black liquor, is possible with a LignoBoost plant. The LignoBoost plant uses sulfuric acid in the process and this results in an increased net input of sulfur to the pulp mills recovery cycle. READ MORE
