  2. 6. Improvement of Wastewater Sludge Digestion

    Author : Michael Recktenwald; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

    Abstract : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. READ MORE

  4. 7. Upflow anaerobic sludge blanket reactor : modelling

    Author : Raul Rodriguez; Luis Moreno; Olle Wahlberg; Gunno Renman; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wastewater; anaerobic treatment; modelling; UASB reactor.; Chemistry; Kemi;

    Abstract : Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant.

  5. 8. Treatment of Textile Wastewater by Combining Biological Processes and Advanced Oxidation

    Author : Marisa Punzi; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Azo dye; textile wastewater; biological treatment; biofilm; microbial community; DGGE; green algae; photo-Fenton; ozone; toxicity; mutagenicity; LCA; cost analysis;

    Abstract : Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. READ MORE

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

    Author : Kimberly Solon; Industriell elektroteknik och automation; []
    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

  7. 10. Treatment of textile wastewaters using combinations of biological and physico-chemical methods

    Author : Maria Jonstrup; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; azo dyes; anaerobic-aerobic treatment; white rot fungi; laccase; photocatalysis; photo-Fenton;

    Abstract : Considerable amounts of water and chemicals are used in the textile industry, and the presence of dyes in the wastewater is a problem of environmental concern. Synthetic dyes are designed to resist light, water and chemicals to improve the quality of the textiles; however, these properties also contribute to their persistence in the environment. READ MORE
