Industrial air pollution can be reduced through various technologies. Flue gas treatment processes are designed to remove pollutants like particulates, sulfur dioxide, and nitrogen oxides from emissions. Key devices include electrostatic precipitators, which use electric charges to capture particles, and scrubbers, which use liquids or slurries to trap gases. For vehicles, catalytic converters oxidize harmful exhaust gases into less harmful substances. Additionally, technologies like scrubbing towers are being developed for carbon capture.
