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

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

    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; [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; Gunaratna Kuttuva Rajarao; Anna Norström; Andres Veide; [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.

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

    University dissertation from Karlstad : Karlstads universitet

    Author : Maria Sandberg; Karin Granström; Jonas Berghel; Alan Werker; [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. Benchmark Simulation Model for Integrated Urban Wastewater Systems : Model Development and Control Strategy Evaluation

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

    Author : Ramesh Saagi; [2017-05-16]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Benchmark Simulation Model; Integrated control strategies; Integrated modelling; River water quality;

    Abstract : The integrated urban wastewater system (UWS) consists of different sections that are interconnected. These include: i) catchment; ii) sewer network; iii) wastewater treatment plant (WWTP); and finally, iv) receiving water system. Traditionally, these sections are operated and evaluated individually.
