Air pollution control methods are used at different stages of Plant Scherer’s production process in order to minimize pollution from emitted gases. The three main pollutants regulated at Plant Scherer, as well as the United States, are particulate matter, NOx, and SO2. These pollutants can cause potential health problems for humans and can damage the environment. An electrostatic precipitator and a baghouse filter are two pollution control methods that focus on particulate matter collection. Flue gas desulfurization is a method that works to mitigate SO2 pollution. Also, selective catalytic reduction is put in place for NOx control. Each air pollution control method at Plant Scherer is further explained in detail.

​An electrostatic precipitator is a control method used for particulate matter collection at Plant Scherer. Electrostatic precipitators consist of discharge wires and collection plates. By applying high voltage to the discharge wires, an electric field forms between the wires and collection plates. When gas that contains particulate matter flows between the collection plates and the wires, the gas becomes ionized and the particulates in the gas become negatively charged by the ions. The negatively charged particulates are then collected by the positively charged collection plates, and the gas then leaves purified. Plant Scherer has an electrostatic precipitator attached to each one of its boiler units. The original installment project of each boiler unit also included an electrostatic precipitator attached to top of each unit (1982, 1984, 1987, 1989).
