  1. 1. Azoles and Contaminants in Treated Effluents Interact with CYP1 and CYP19 in Fish

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kristina Beijer; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Azole; fungicide; chemical; CYP1A; CYP19; EROD; aromatase; effluent; STP; wastewater; fish; stickleback; rainbow trout; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : Numerous contaminants are present in mixtures in the aquatic environment. Among these are the azoles, a group of chemicals that includes both pharmaceuticals and pesticides. Azole fungicides are designed to inhibit lanosterol 14-demethylase (cytochrome P450 (CYP) 51), while other azoles are intended to inhibit aromatase (CYP19), i.e. READ MORE

  2. 2. Pharmaceutical compounds; a new challenge for wastewater treatment plants

    University dissertation from Stockholm : KTH

    Author : Maja Dlugolecka; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; biodegradation; granular activated carbon GAC ; membrane bioreactor MBR ; pharmaceutical compounds; wastewater; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Vattenteknik;

    Abstract : Analytical analyses conducted at the Himmerfjärden WWTP (285.000 PE connected) identified 70 pharmaceutical compounds belonging to different therapeutic classes. Such organic micropollutants at low detected concentration range of µg - ng l-1 did not affect the treatment processes at WWTP. READ MORE

    Abstract : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. READ MORE

  4. 4. Degradation of organic matter in wastewater -Enhanced denitrification and removal of refractory organics

    University dissertation from Chemical Engineering, Lund University

    Author : Marinette Hagman; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; leachate; denitrification; carbon source; advanced oxidation; Activated sludge; wastewater; oxygen uptake rate; ozone;

    Abstract : Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. READ MORE

  5. 5. Microsieving in municipal wastewater treatment : Chemically enhanced primary and tertiary treatment

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Janne Väänänen; Lunds universitet.; Lund University.; [2017-02-02]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coagulation; wastewater treatment; flocculation; microsieving; control; primary treatment; tertiary treatment; coagulation; control; flocculation; microsieving; municipal wastewater treatment; primary treatment; tertiary treatment;

    Abstract : Municipal wastewater treatment plants are constantly forced to make improvements. The main objectives are to reduce energy consumption, to increase the treatment capacity and to improve the effluent water quality. Microsieves in combination with chemical pretreatment can potentially fulfil these objectives. READ MORE
