“…If the dosed persulfate was completely decomposed, formed sulfate at concentrations of 800 mg/L and 1200 mg/L would be achieved when the dosages of persulfate were 1000 mg/L and 1500 mg/L, respectively. A sulfate concentration that is higher than 600 mg/L in drinking water might cause taste alteration and diarrhea [54]. However, it should be noted that the concentrations of M. aeruginosa in most source waters were always lower than 10 6 cells/mL.…”

Cyanobacteria blooms in source waters have become a worldwide issue for drinking water production. UV-activated persulfate (UV/PS) technology was firstly applied to remove cultivated Microcystis aeruginosa in bench scale. The presence of persulfate significantly enhanced both cytoclasis and algal organic matter mineralization compared with UV-C inactivation alone. Around 98.2% of algal cells were removed after UV/PS process treatment for 2 h at a dosage of PS being 1500 mg/L (approximately 6 mM). Both sulfate and hydroxyl radicals were proven to contribute

“…The industrial wastewater is limited to under 500 mg/L sulfate in the legislation of many countries [13]. Several research have been reported for efficient removal of lead and sulfate from wastewater such as ion exchange [14][15][16], electrochemical reduction [17], activated carbon [18,19], biosorption [20], adsorption [21][22][23], and membrane separation [24]. The efficiency of these methods depends on the lead and sulfate concentration, pH, the economics involved, and social factor set in the standard of government agencies.…”

In this study, we present a low-cost and simple method to treat spent lead–acid battery wastewater using quicklime and slaked lime. The sulfate and lead were successfully removed using the precipitation method. The structure of quicklime, slaked lime, and resultant residues were measured by X-ray diffraction. The obtained results show that the sulfate removal efficiencies were more than 97% for both quicklime and slaked lime and the lead removal efficiencies were 49% for quicklime and 53% for slaked lime in a non-carbonation process. After the carbonation step, the sulfate removal efficiencies were slightly decreased but the lead removal efficiencies were 68.4% for quicklime and 69.3% for slaked lime which were significantly increased compared with the non-carbonation process. This result suggested that quicklime, slaked lime, and carbon dioxide can be a potential candidate for the removal of sulfate and lead from industrial wastewater treatment.

“…Bu modele göre qm değerleri Amberlite IRA 67 için 66,4; Amberlyst A23 için 281,2 ve Lewatit MonoPlus MP 62 için 796,1 mg/g olarak hesaplanmıştır [19]. Benzer sonuçlar Amberlyst A21 kullanılarak sulu çözeltilerden sülfat giderimi [29] ve reaktif boyaların Amberlite IRA-900 kullanılarak sulu çözeltilerden giderimi [30] için yapılan çalışmalardan da görülmektedir.…”
