    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluoride removal; Groundwater; Natural minerals; Adsorption isotherms; Batch- and Column Experiments; Kinetics and thermodynamics; Drinking water quality; Sustainability; Kuondolewa kwa fluoride; Maji ya chini ya ardhi; Madini ya asili; isotherms za majaribio ya adsorbenti; Majaribio ya Kundi- na Safu; Kinetics na thermodynamics; ubora wa maji ya kunywa; Uendelevu; Fluoridavlägsnande; Grundvatten; Naturliga mineraler; Batch- och kolonnförsök; Adsorptionsisotermer; Kinetik och termodynamik; Dricksvattenkvalitet; Hållbarhet; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Fluoride (F-) concentration in drinking water is one of the water quality parameters in countries with high concentrations in groundwater sources. Natural minerals have shown considerable effectiveness in F- removal. LÄS MER

  3. 2. Hydrogeochemistry of arsenic, fluoride, and other trace elements in groundwater in northern Tanzania : Occurrence, distribution, and impacts on drinking water quality

    Författare :Fanuel Josephat Ligate; Prosun Bhattacharya; Felix W Mtalo; Jyoti Prakash Maity; Joyanto Routh; KTH; []
    Nyckelord :Arsenic; Fluoride; Groundwater; Lake Victoria basin; Risk assessment; Sanya alluvial plain; Tanzania.; Aseniki; Bonde la Ziwa Victoria; Floridi; Maji yaliyopo ardhini; Tanzania; Tathmini ya hatari; Uwanda wa Aluvia ya Sanya.; Arsenik; Fluorid; Grundvatten; Viktoriasjön; Riskbedömning; Sanya alluvial slätt; Tanzania.; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : The occurrence of arsenic (As), fluoride (F-), and other trace elements (TEs) with potential toxicity in groundwater is a global environmental concern. According to the National water resource mapping database, about 76 % of the drinking water supply in Tanzania is abstracted from groundwater sources. LÄS MER

  4. 3. Spatial variability of geogenic contaminants in drinking water sources : Insights into hydrogeological controls, geospatial data for safe water supply and groundwater resource management

    Författare :J. Ijumulana; Prosun Bhattacharya; Felix Mtalo; Steve W. Lyon; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drinking water; geogenic contaminants; potentially toxic elements; fluoride; spatial analysis; spatial variability; Tanzania; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : The presence of geogenic contaminants in drinking water is a major health concern in many parts of the world. The interaction of groundwater with different rock types and sediments in the natural geochemical environment play an important role in controlling their mobility. LÄS MER
