  1. 1. Investigations of the microbial diversity and dynamics in activated sludge using molecular methods

    University dissertation from Chalmers University of Technology

    Author : Johan Fredriksson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; activated sludge; microbial ecology; population dynamics; Bacteria; Archaea; 16S rRNA; terminal restriction fragment length polymorphism;

    Abstract : Wastewater treatment is necessary to reduce the health risks and environmental impacts associated with discharge of untreated wastewater. The most common way to treat wastewater in wastewater treatment plants is through the activated sludge process. READ MORE

  2. 2. Extending Wastewater Treatment Process Models for Phosphorus Removal and Recovery : A Framework for Plant-Wide Modelling of Phosphorus, Sulfur and Iron

    University dissertation from Division of Industrial Electrical Engineering and Automation, Faculty of Engineering, Lund University

    Author : Kimberly Solon; Lunds universitet.; Lund University.; [2017-04-24]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Benchmark Simulation Model; Anaerobic Digestion Model; Activated Sludge Model; Physico-chemistry; Phosphorus removal; Nutrient recovery;

    Abstract : As problems associated with shortage in resource supply arise, wastewater treatment plants turn to innovation to transform themselves into resource recovery facilities. Water groups worldwide recognize that wastewater treatment plants are no longer disposal facilities but rather sources of clean water, energy and nutrients. READ MORE

  3. 3. Coagulant Protein from plant materials: Potential Water Treatment Agent

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Ida Bodlund; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antimicrobial effect; Brassica; coagulant protein; MO2.1; Moringa oleifera; Mustard; napin; thermo-resistance; plant material; protein extraction; salt extract.;

    Abstract : Access to fresh water is a human right, yet more than 780 million people, especially in rural areas, rely on unimproved sources and the need for finding ways of treating water is crucial. Although the use of natural coagulant protein in drinking water treatment has been discussed for a long time, the method is still not in practice, probably due to availability of material and limited knowledge.

    Abstract : Popular Abstract in English Improving irrigation practices and optimal exploitation of available water resources are vital issues facing water scarcity and similar problems in arid and semiarid countries (e.g., Egypt and Tunisia). In these countries, the use of saline and low quality irrigation water (i. 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
