15 Ιουλ 2023 · Ion exchange is a known wastewater treatment process which can be used to remove the sulphate ion from wastewater through exchanging the ions between the ion exchanger (resin) and liquid (contaminated water).
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 · This study contributes to a strategy for controlled separation of sulfate using a sustainable biocomposite material that is suitable for fixed-bed column point-of-use water treatment...
1 Νοε 2018 · Examples of such processes include alternative chemical precipitation methods, membrane technology, biological treatment, ion exchange, and adsorption. In addition, aqueous chemistry and current effluent standards concerning sulfate together with concentrate treatment and sulfur recovery are discussed. 1.
The major criteria used to select the sulfate–removal treatment process were, in order of importance: 1) Capability to remove sulfate consistently to < 600 mg/L; 2) Treatment costs, which included examining the amounts of wastes generated by the treatment process; 3) Ease–of– operations.
6 Ιαν 2015 · Many treatment technologies have been developed and refined to remove sulfate from water, including chemical, biological, and physical processes. Chemical Treatment Technologies. Chemical methods for reducing sulfate concentrations include: Lime precipitation; Barium precipitation; The CESR process; The SAVMIN™ process
This paper presents a high-level comparison of four sulphate removal technologies, namely reverse osmosis, ettringite precipitation, barium carbonate addition, and biological sulphate reduction. Primarily operating costs, based on reagent and utility consumptions, are compared.
