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

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Janne Väänänen; [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

  2. 2. Municipal wastewater treatment by microsieving, microfiltration and forward osmosis : Concepts and potentials

  3. 3. Antibiotic Resistance in Wastewater Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Stefan Börjesson; Per-Eric Lindgren; Johanna Ericson Sollid; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi;

    Abstract : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. READ MORE

  4. 4. Efficient treatment of forest industrial wastewaters Energy efficiency and resilience during disturbances

    University dissertation from Karlstad : Karlstads universitet

    Author : Maria Sandberg; Karlstads universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest industry; wastewater; oxygen transfer rate; black liquor; surface active; extractives; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : This work concerns the efficient treatment of wastewaters from pulp and paper mills by means of aerobic biological processes. For treatment processes there are many aspects of efficiency and the present study investigates both energy efficiency and purification efficiency during disturbances. READ MORE

  5. 5. Microbiological analysis of municipal wastewater treating photobioreactors

    University dissertation from Västerås : Mälardalen University

    Author : Ivo Krustok; Mälardalens högskola.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photobioreactors; wastewater treatment; microalgae; microbiology; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Microalgae reactors, commonly known as photobioreactors, have become increasingly popular as an alternative for wastewater treatment. These systems reduce pollutants and remove nutrients such as nitrogen and phosphorous compounds from wastewater utilizing microalgae and bacteria. READ MORE
