“…As can be seen in Figure 5b, the COD/sulphate ratio shows similar direction and length to Cd removal parameters while also exhibits an inverse direction to Cr and Pb removal. This finding further supports previous discovery that found higher COD/Sulphate increases the abundance SRB communities that enhances sulphate reduction, while Cd precipitates faster during the sulphate reduction process compared to the other heavy metals (Virpiranta et al, 2022). This study marks a stride in comprehending the significance of SRB utilization in pilot scale wastewater treatment plant treating laboratory wastewater that contained heavy metals.…”

Heavy metals in wastewater come from processes related to heavy metals as raw materials and contaminants. Heavy metals pose a significant threat. Bioaugmentation technique that utilizes communities of microorganisms to bioaccumulation heavy metals from wastewater. However, the application of SRB in anaerobic system installations for wastewater treatment needs to continue to be developed with more practical applications. In this study, the enriched SRB colony source was applied to an anaerobic tank. The grown SRB is used to extract heavy metals from wastewater with the addition of sulfate and supporting nutrients. Throughout the treatment process, the anaerobic system with SRB consistently maintained a sulfate removal efficiency of 87-88%, indicating continued sulfate consumption activity by the SRB colony. Despite the high initial concentration of heavy metals, the system effectively removed > 91% of Pb, Cd, Zn, and Cr on days 15, 30, and 45. Additionally, the system reduced the Cu content by 43.6%, thereby reaching peak metal removal heavy. the level was 85% on day 30 and decreased slightly to 83% on day 45. This study bridges the gap in understanding the application of SRB in wastewater treatment systems with effective performance.

“…Figure 2 shows the S2p high resolution spectrum of the recovered PG-Peat. The doublet with a binding energy difference of 1.4 eV could be seen at 168 eV for S2p 3/2 and at 169.4 eV for S2p 1/2 , which can be attributed to sulfate (Gogoi et al 2019;Virpiranta et al 2022), thus confirming the binding of sulfate ions onto the PG-Peat during the ion exchange process.…”

This paper presents the results of wastewater treatment at a mining enterprise developing a complex ore deposit in the Murmansk region, Russia. The main pollutants are sulfate, manganese, and strontium. For this complex wastewater treatment, a two-stage scheme was proposed and tested using two sorbents (at a pH of 6): an aminated peat biosorbent to remove sulfate and a commercial sorbent based on the mineral brucite to remove metals. Optimal conditions were established for purifying the wastewater of sulfate and manganese and strontium ions to the level of maximum available concentrations in water bodies for fishery purposes.

“…Research articles on sulfate removal are widely available in the scientific literature. [12][13][14][15][16] This survey covers a variety of approaches and techniques to treat streams with different levels of sulfate concentration, with a particular focus on streams that have low concentrations of this ion, i.e., lower than 2,000 mg L -1 . These studies not only address sulfate removal to comply with environmental regulations when disposing of effluents into water bodies, but also consider the importance of water reuse in industrial processes.…”

Sulfate is a common ion present in natural water bodies at low concentrations and as effluent in different metallurgical processes. The discharge of sulfate in rivers and waterbodies can cause direct and indirect damage to the environment. Regulatory agencies have been increasing the constraints in sulfate content limit for discharge focused on human equity and environmental protection. A common practice is the precipitation of sulfate with lime, but the remaining solution still has ca. 1,500 mg L-1 of sulfate, which is not acceptable for disposal or reuse. This work describes the main routes for sulfate removal such as chemical precipitation, biological degradation, ion exchange, and separation through membranes and discusses the main advantages and issues of each approach. One of the main challenges is to scale up the tests and show the performances at the industrial level. The subject must be the focus of constant study to obtain relevant results so that usual technologies are replaced by more innovative, cheap and efficient methods.
