  2. 1. Sustainable Arsenic Mitigation A Strategy for Scaling-up Safe Water Access : A Strategy for Scaling-up Safe Water Access

    Author : Mohammed Hossain; Prosun Bhattacharya; Marinus Eric Donselaar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bangladesh; drinking water; arsenic mitigation; local tubewell driller; sediment color tool; low-manganese; Intermediate Deep aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : In rural Bangladesh, the drinking water supply is mostly dependent upon manually operated hand pumped tubewells, installed by the local community. The presence of natural arsenic (As) in groundwater and its wide scale occurrence has drastically reduced the safe water access across the country and put tens of millions of people under health risk.

  4. 2. Application of magnetic nanoparticles and reactive filter materials for wastewater treatment

    Author : Ramnath Lakshmanan; Gunaratna Kuttuva Rajarao; Erik Dahlquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reactive filter materials; magnetic nanoparticles; wastewater treatment process; nutrient reduction; sludge water content; toxicity of magnetic nanoparticles;

    Abstract : Lately sewage wastewater treatment processes (WWTP) are facing challenges due to strict regulations in quality of effluent standards and waste production. The reuse of wastewater treatment effluents is rapidly gaining attention as a means of achieving sustainable water supply. Therefore, new methods are required to achieve an efficient WWTP. READ MORE

  5. 3. Application of satellite data for investigation of water quality in coastal areas

    Author : Chuqun Chen; Avdelningen för Teknisk vattenresurslära; []
    Keywords : Atmospheric correction; Pearl River estuary; Daya Bay.; Numerical modeling; Chlorophyll-a; Water quality; Ocean color remote sensing; Gelbstoff;

    Abstract : The population growth in China together with the rapid industrialization and urbanization have increased the utilization of natural resources, leading to more waste being released to the environment. Thus, the environmental conditions have degraded in many regions to a point where environmentally related problems have become the main limiting factors for economical development and social progress.

  6. 4. Latex Colloid Dynamics in Complex Dispersions : Fluorescence Microscopy Applied to Coating Color Model Systems

    Author : Gunilla Carlsson; Jan van Stam; Maria da Graca Miguel; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; coating color; colloid; latex; diffusion; Brownian motion; film formation; polymer interaction; Physical chemistry; Fysikalisk kemi; Kemi; Chemistry;

    Abstract : Coating colors are applied to the base paper in order to maximize the performance of the end product. Coating colors are complex colloidal systems, mainly consisting of water, binders, and pigments. To understand the behavior of colloidal suspensions, an understanding of the interactions between its components is essential.. READ MORE

  7. 5. Brownification of freshwaters - the role of dissolved organic matter and iron

    Author : Sara Ekström; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brownification; freshwater; water color; dissolved organic matter DOM ; iron Fe ; decreasing acidification; climate change;

    Abstract : The term brownification refers to the trend of increasing water color, i.e. the water becoming browner, which has been observed throughout the northern hemisphere over the last decades. Brownification has both ecological and societal implications. READ MORE
