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

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Chronic kidney disease (CKD) is a major health problem and an economical burden affecting people worldwide. The main causes of CKD are diabetes and hypertension and patient numbers keep increasing. LÄS MER

  5. 19. Trace metal speciation in fresh and brackish waters using ultrafiltration, DGT and transplanted aquatic moss

    Författare :Jerry Forsberg; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Distribution, mobility, and toxicity of metals in natural waters are strongly related to their aqueous speciation. To understand the behaviour of an aqueous element and the transformation between chemical species, there is a need for reliable methods that enable measurements of specific fractions of metals.

  7. 20. Icodextrin metabolism in peritoneal dialysis : clinical and experimental studies

    Författare :Elvia García López; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Peritoneal dialysis; icodextrin; icodextrin metabolites; ultrafiltration; alphaarnylase activity; gel-filtration HPLC;

    Sammanfattning : Icodextrin (ICO, or polyglucose) is an effective osmotic agent for peritoneal dialysis (PD) patients (pts). ICO is a soluble polymeric form of glucose with an average molecular 'weight range from 13,000 to 19,000 dalton. Glucose is absorbed from the peritoneal cavity by diffusion. LÄS MER
