In this article, a new type of coagulant material has been investigated and the performance of the coagulation process using this type of coagulant was evaluated. This new type is a combination of zinc oxide nanoparticles and polyferric sulfate (ZnOPFS). The structure of zinc oxide nanoparticles was determined by spectroscopic, X-ray and electron microscopy methods, and based on this, it was determined that ZnOPFS is a complex and mixed compound that is mainly composed of zinc oxide nanoparticles and ferric sulfate. The effects of Zn/Fe (Zn/Fe) molar ratio and aging (time) on acidity and zeta potential were also evaluated using a specific method. The obtained results showed that in the simultaneous deposition process, zinc ions can prevent the formation of polyferric acid coagulation and subsequently improve the stability of ZnOPFS.

“…Many different processes are used to refine natural gas and bring it to pipeline gas quality for transmission. Sulfur is usually present as an impurity in fossil fuels [1] [2] [3]. With the combustion of fuels, sulfur is released in the form of sulfur dioxide, an air pollutant, which itself is the cause of respiratory problems and acid rain [4] [5] [6].…”

The sour gas sweetening is one of the main processes in gas industries. Gas sweetening is done through chemical processes. Therefore, it requires high cost and energy. The results show that increasing the operating temperature increases the mass transfer coefficient and increases the mass transfer rate. Theoretical and experimental data show that sulfur removal in 4.5 W magnetic field is desirable. The increase in sulfur removal percentage in the magnetic field of 4.5 W and 6.75 W is about 16.4% and 15.2%, respectively. According to the obtained results, the effect of temperature increase from 18.8˚C to 23.4˚C is more evident than the effect of temperature change from 23.4˚C to 32.2˚C. Because more thermal energy is needed to provide higher temperatures. Therefore, the temperature of 23.4˚C is reported as the optimal temperature. The results of this research show that the percentage of sulfur removal is also high at this temperature.

Wastewater can be contaminated with all kinds of microorganisms and small organisms, including bacteria, parasites, fungi and viruses. Therefore, it can be said that biological pollution is one of the most dangerous pollutions. These types of pollution can endanger human health and the environment. In this study, industrial wastewater disinfection has been investigated in a laboratory pilot. In this study, ultraviolet waves have been used for wastewater disinfection. In this research, treatment indicators such as wastewater pH, phosphate, nitrate, biological oxygen and chemical oxygen, organic carbon, and wastewater turbidity have been investigated. The results of this research show that if 4.5 g of dry ice is added to the wastewater entering the disinfection unit, the pH of the wastewater will decrease to about 7.9. The results presented from the disinfection unit show that the amount of chemical oxygen demand and biological oxygen demand have decreased by about 35% and 20.3%, respectively. The results of this unit show that the amount of phosphate and nitrate has decreased by 61.3 and 71.9%, respectively. Laboratory results show that the TDS of wastewater has decreased from 600 to 451 mg/l.
