  • Wetlands act as valuable urban water treatment

    As cities and urban landscapes expand across the globe, water resource management continues to pose a huge challenge. Natural wetlands are often built over as cities grow, but a recent strategy of green infrastructure applies the opposite principle – wetlands are protected and constructed as part of city planning. Wetlands, whether natural or man-made, act as large-scale storage and ...

  • Comparative analysis of two low cost point-of-use water treatment systems

    The study examined two low-cost point-of-use water treatment systems developed in respect of bacterial and particulate removal when exposed to surface water for three months. Bacterial removal efficiency was estimated using E. coli and fecal coliforms, while particulate reduction efficiency was estimated by determining turbidity and total suspended solids (TSS). The systems investigated were ...

  • Removal of antibiotic resistant E. coli in two Norwegian wastewater treatment plants and by nano- and ultra-filtration processes

    The effectivity of different treatment stages at two large wastewater treatment plants (WWTPs) located in Oslo, Norway, to remove antibiotic resistant Escherichia coli from municipal wastewater was investigated. The WWTPs were effective in reducing the total cultivable E. coli. The E. coli in WWTP samples were mainly resistant to ampicillin (6–27%) and ...

  • Sodium hypochlorite dosage for household and emergency water treatment: updated recommendations

    Household water treatment with chlorine can improve the microbiological quality of household water and reduce diarrheal disease. We conducted laboratory and field studies to inform chlorine dosage recommendations. In the laboratory, reactors of varying turbidity (10–300 NTU) and total organic carbon (0–25 mg/L addition) were created, spiked with Escherichia coli, and dosed with 3.75 mg/L ...
