Question

Discuss the three methods of controlling water pollution.

Answer 1

Three measures of controlling water pollution:

Government protection low

• All factories and municipal corporations are responsible for the discharge of wastewater and have to treat it to remove harmful constituents.
• The wastewater released into the water body must meet norms fixed by the government.

Sewage converted into a useful product

• The solids removed by sedimentation can be used to generate the biogas which is a clean fuel.
• the residue from biogas generation makes good organic manure.
• the water obtained from the sewage can be used in irrigation after the removal of all impurities.

Use of the eco-friendly products

• The use of chemical fertilizer and pesticides should be minimized and replaced by the eco-friendly product.
