Currently, there are two primary methods being used by industries and power plants to reduce the amount of pollutants released into the atmosphere.
Electrostatic precipitators are less effective than scrubbers.
They are designed to remove the visible soot from the emissions. This makes the emissions look clean but does not remove the real culprits of acid rain, SO 2 and NO x . Cleaner vehicles are produced in the United States which recirculate automobile exhaust back to the engine in order to burn extra NO x . Many people think that catalytic converters do this job, but this is not true. By increasing the number of electric vehicles on the road we can decrease the total amount of NO x emissions from automobiles.
