“…The high levels in the different sampling stations allow us to classify this water in the "polluted" category [10] [11]. In addition, the high concentration of 4 NH + would affect the water quality, the self-cleaning capacity of the water sources and, the death of fish and aquatic organisms [3]. The high concentrations of PO − may be due to the influence of waste from the residential community.…”

“…It receives particular attention because it is a means of energy recovery from organic waste [2]. Indeed, the anaerobic digestion of organic waste offers possibilities for energy and nutrient recovery [3]. Thus, it reduces the impact of waste on the environment, while producing renewable energy and thus contributing to a reduction in greenhouse gas emissions [2].…”

“…Anaerobic digestion is the main technology used in wastewater treatment. In the previous studies, anaerobic digestion was used to treat slaughterhouse wastewater with 95.90% COD (600 mg/L) removal [ 49 ] and 98.4% COD (100–600 mg/L) removal for nitrogen fertilizer wastewater [ 50 ]. Compared with the current study, sulfur convertase removed more COD, but the removal rate was much lower than in the previous studies.…”

Sulfide is a toxic pollutant in the farming environment. Microbial removal of sulfide always faces various biochemical challenges, and the application of enzymes for agricultural environmental remediation has promising prospects. In this study, a strain of Cellulosimicrobium sp. was isolated: numbered strain L1. Strain L1 can transform S2−, extracellular enzymes play a major role in this process. Next, the extracellular enzyme was purified, and the molecular weight of the purified sulfur convertase was about 70 kDa. The sulfur convertase is an oxidase with thermal and storage stability, and the inhibitor and organic solvent have little effect on its activity. In livestock wastewater, the sulfur convertase can completely remove S2−. In summary, this study developed a sulfur convertase and provides a basis for the application in environmental remediation.

“…They must be treated without first being released into the environment. [1] If the electroplating wastewater discharged in to the natural water bodies without treatment caused adverse effects to the aquatic fauna. For the treatment of heavy metals, a number of methods have been used, including precipitation, adsorption, ion-exchange, and membrane process.…”

Studies have been conducted into the effectiveness of electro coagulation in the treatment of wastewater containing metal ions (Fe, Zn, Cr, Mn, and Cu). Several operational criteria, including Time, pH, Current, Voltage, combination of electrodes like Fe-Fe, Fe-Al, Al-Al &Al-Fe were evaluated in an attempt to enhance removal efficiency. In addition, the increase of voltage 2.5V, 5V, 10V accordingly the current density also varied 0.12A, 0.24A, 0.53A respectively. The amounts recovered from Iron, Manganese, Copper, Zinc was discovered to be substantially faster than Chromium as a result of different removal strategies. The method was effectively used to treat effluent from electroplating, where an optimum decrease of (Fe, Zn, Cr, Mn, Cu) concentrations beneath permissible limits was obtained, just after 60 min. The 100 percent removal efficiency of Zn, Cr, Cu, Mn were obtained by using the Fe-Fe electrode with 10V and 60 minutes. The iron was removed 100 percent in the combination of Al-Al electrode with 10V and 60 minutes. At the increased time interval, the use of iron electrode increases the concentration of Fe, because iron electrode was the sacrificial electrode.
