5.14.5. Control Measures:

Reducing or eliminating the sources of pollution by

♤ Buffering- the practice of adding a neutralizing agent to the acidified water to increase the pH is one of the important control measures. Usually lime in the form of calcium oxide and calcium carbonate is used.

♤ Reducing the emission of SO2 from power stations by burning less fossil fuel, using alternate energy sources like tidal, wind, hydropower etc.,

♤ using low sulphur fuel;

♤ desulphurization

♤ decreasing emission of NOx from power stations and

♤ Modification of engines.

♤ Emissions of SOx can be controlled by

♤ Converting to sulphuric acid.

♤ Converting it to elemental sulphur.

♤ Neutralizing it and using it in the manufacture of other products.
