  2. 1. Modern Artificial Recharge Plants : Combining chemical flocculation with aquifer recharge

    Author : Kristofer Hägg; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Natural organic matter NOM ; Chemical flocculation; Ultrafiltration membrane; Disc filtration; Managed Aquifer Recharge;

    Abstract : Water supply security is increasingly becoming a challenge worldwide. Surface waters, which are often used for drinking water production, have experienced an increase in natural organic matter (NOM) and frequency of algae blooms. Water quantity is also an issue due to increasing populations and potable water demand. READ MORE

  4. 2. Floodwater harvesting for artificial recharge of groundwater - estimation and prediction for arid Iran

    Author : Hossein Hashemi; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial recharge; Groundwater modeling; Climate change; Spate irrigation; Arid area; FWS; GBP;

    Abstract : Groundwater depletion in arid and semiarid areas is of increasing concern. Increasing water demand due to increasing population and climate change impacts have intensified the water shortage problems and put further stress especially on groundwater. READ MORE

  5. 3. Artificial recharge of groundwater for public water supply : potential and limitations on boreal conditions

    Author : Cristina Frycklund; KTH; []
    Keywords : ;

    Abstract : It is motivated by the intentions of Agenda 21 to findalternatives to the increasing dependence on chemical treatmentin the production of public water. Conventional waterworkscommonly include chemicals for removal of organic compounds,for reduction of corrosiveness and for disinfection. READ MORE

  6. 4. Modelling Freshwater-Seawater Interactions in Coastal Aquifers : Long-term Trends and Temporal Variability Effects

    Author : Carmen Prieto; KTH; []
    Keywords : seawater intrusion; seasonal variability; artificial recharge; spatial and temporal randomness;

    Abstract : Over-exploitation of coastal aquifers causes seawaterintrusion and eventually contamination of groundwater wells inmany parts of the world. Desalination of brackish water andartificial recharge of treated wastewater may then be asustainable strategy for managing groundwater supply inwater-stressed regions. READ MORE

  7. 5. Managing Eutrophic Waters in Artificial Recharge Plants : Cyanotoxin risk in Swedish freshwaters

    Author : Jing Li; Avdelningen för Teknisk vattenresurslära; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drinking water; cyanobacterial blooms; cyanotoxins; nutrients; total phosphorus; DIN TP; quick test kit;

    Abstract : In the last decades, the frequency and intensity of cyanobacterial blooms have been of increasing concern. They have become a direct threat to the drinking water supply by clogging filters, bringing odour and unpleasant taste to the treated water and worst of all, causing elevated cyanotoxins, which can be difficult to remove, yet lead to severe health issues.
