  3. 2. 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

  4. 3. Optimizing Sample Dissolution Methods of Low Water Soluble Intermediate Organic Compounds to Support Environmental Risk Assessment during Active Pharmaceutical Ingredient Manufacturing.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Warda Mohammed; [2021]
    Keywords : Active pharmaceutical ingredient; API; total organic content; TOC; chemical oxygen demand COD; biological oxygen demand; BOD; Microtox; octanol-water partition coefficient; Kow; solubility.;

    Abstract : This project focus on investigating the dissolution of low water-soluble intermediate organic compounds called active pharmaceutical ingredients (API) and organic substances that are manufactured by a pharmaceutical company, Cambrex Karlskoga in Sweden. Several dissolution methods were used and evaluated using methods including total organic carbon (TOC), chemical oxygen demand (COD), biochemical oxygen demand (BOD) and Microtox toxicity test.

  5. 4. Modeling BOD removal in free watersurface constructed wetlands with variable residence time-based methods

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Degefu Yohannes Sebro; [2021]
    Keywords : BOD removal; Free water-surface constructed wetlands; VART-BOD; models; dynamic diffusion zone; Technology and Engineering;

    Abstract : Constructed wetlands (CWs) have been applied for several years in the removal process pollutants from secondary treatment plants and stormwater. In this paper, the Variable Residence Time (VART) model for solute transport in streams was extended to simulate the BOD removal process in free water surface flow constructed wetlands (FWS CWs).

  6. 5. Water Pollution and Economic Growth

    University essay from Umeå universitet/Nationalekonomi

    Author : Albin Magnusson; [2021]
    Keywords : ;

    Abstract : Water pollution is a cornerstone of environmental issues, where it not only harms human health but also has major economic consequences. This study examines whether there is proof of the inverted U – shape Environmental Kuznets Curve (EKC) between water pollution and GDP per capita for 16 European countries between the years 1992 and 2018.
