In weathering or contact with aerated water, the sulfides are oxidized to yield sulfate ions which are carried off in the water. Sulfate is carried to bodies of water by rain and through solution of sulfate compounds in sedimentary geologic formations within the drainage basin.
24 Νοε 2020 · Sulphate (SO42-) concentrations in freshwaters have increased globally over the last decades even though a strong reduction in atmospheric sulphur (S) deposition has occurred across large parts...
1 Ιαν 2021 · Sulphate (SO 4 2−) is a common anion nutrient naturally occurs in water bodies, and considered not toxic when presented in low concentration. However, the presence of large amounts of SO 4 2− induces sour taste in household water and scaling in pipe lines.
sulfate (alum) is used as a sedimentation agent in the treatment of drinking-water. Copper sulfate has been used for the control of algae in raw and public water supplies (McGuire et al., 1984).
1 Φεβ 2020 · Sulfate ion (SO 4 2− ) is a type of anions which are widely present in natural water body and industrial wastewater.
1 Μαρ 2018 · Several novel processes have been introduced to treat the sulphate in contaminated water and suitability of the option may depend on the requirement and the economy. For example, AMD treatment with granular activated carbon (GAC) and phytoremediation have recently captured greater attention of the scientific community.
1 Φεβ 2003 · Laboratory studies using bentonite showed poor or no removal in the case of high sulfate water. Ion exchange and nanofiltration were found to be very effective in removing sulfate.
