Aerosol formation by heterogeneous reactions in ammonia-based WFGD systems

Friedel’s Salts Synthesis and Adsorption Applications in the Removal of As(III) and Se(IV) from Desulfurization Wastewater

“…In the context of increasingly serious arsenic and selenium pollution and tightening environmental policies and laws, , it is crucial to control arsenic and selenium emissions from coal-fired power plants . The application of the limestone-gypsum wet flue gas desulfurization technology is a common method for treating arsenic and selenium in the industry, but the resulting desulfurization wastewater has a complex composition, contains a variety of heavy-metal ions and salt ions, and is characterized by high corrosion and scaling, making it one of the most difficult wastewaters to treat in thermal power plants. − Wastewater pollution is causing increasing environmental problems, and scientists have been trying to develop new means of wastewater treatment to overcome the secondary pollution and waste of resources caused by the traditional triplex tank process. , …”

Chloride Ion Removal from the Wet Flue Gas Desulfurization and Denitrification Wastewater Using Friedel’s Salt Precipitation Method

“…e wet flue gas desulfurization (WFGD) technology is one of the world's most widely used flue gas desulfurization technology due to its high desulfurization efficiency and low investment and operationg costs [1]. Meanwhile, in order to cost-effectively control SO 2 , NOx and other pollutants in the flue gas, scholars have developed a variety of multipollutant cooperative control technologies based on the WFGD in recent years.…”
