“…Due to its toxicity to the environment, sulfate is one of the main industrial pollutants that has drawn a lot of attention in water research [3]. High levels of sulfur in the water bodies cause several environmental issues, including the mineralization of water, disruption of the natural sulfur cycle and food chain, and atmospheric emission of hydrogen sulfide [4]. Sulfate removal has traditionally been accomplished using conventional wastewater treatment methods.…”

Using physical activation, a new composite adsorbent was prepared by modifying low-cost local adsorbent. This low-cost local adsorbent was also prepared from activating sludge, bentonite, and limestone (SBL). In comparison to the low-cost LCL, the adsorption capacity of the new composite adsorbent was improved. This was measured in terms of its ability to remove sulfate from wastewater. The behavior of the sulfate adsorption processes by using (SBL) as an adsorbent was investigated in batch experiments by examining different values of solution pH, contact time, adsorbent dose, and initial SO4 concentration. The high removal efficiency was exhibited by (SBL) = 96%. These results reveal the great potential of the new composite adsorbent (SBL) if applied to the absorption of sulfate ions.
