We investigated the reducing rate of manganese oxides (MnOs) and organic matter in water by using pre-oxidation and coagulation/sedimentation methods with different chemicals. The reduction rate using NaOCl for organic matter was about 11%, while tha

Researchers are in continuous search of better strategies to minimize, if not prevent, the anthropogenic release of toxic heavy metals, such as Cu(II) and Pb(II), into drinking water resources and the natural environment. Herein, we report for the fi

In this study, manganese dioxide (MnO2) derived from groundwater treatment sludge was used in the adsorption of nickel (Ni(II)) ions from aqueous solutions. The synthetic MnO2 was prepared via permanganate reduction using manganese extracted from the

In this study, the potential of groundwater treatment sludge reuse in the adsorption of nickel ions from aqueous solutions was evaluated. The effects of varying solution pH (4.5, 5.5, 6.5, 7.5), initial nickel concentrations (10, 50, 100, 200 mg L−

Groundwater treatment residuals are rich in nano-sized metal oxides which have the potential to remove various water contaminants. In this study, hexavalent chromium adsorbents were synthesized from the residuals of a 30,000 m 3 d -1 groundwater trea

In the establishment of the groundwater management index of the Szuchung Hot-Spring Area, the sensitivity of the temperature change is much smaller than the sensitivity of the groundwater level change. Therefore, only the groundwater level can be use

Removal of algae via coagulation with magnetic MnFe2O4 recycled from drinking-water treatment sludge
Publikováno v:
2018 IEEE International Conference on Applied System Invention (ICASI).
In water treatment plants, oxidizing agents (e.g., NaOCl) are commonly added prior to coagulation. This reduces algae activity and enhances coagulation effectiveness. However, oxidants generate harmful by-products (e.g., trihalomethanes, THMs). Landf
