Answer: A variety of strategies can be used to control water pollution to a greater extent. Rather than dumping sewage waste into bodies of water, it is preferable to treat it first. By doing so, the original toxicity can be reduced, and the leftover compounds can be decomposed and turned harmless by the water body. Water that has undergone secondary treatment can then be reused in sanitary systems and agricultural fields.
The Water Hyacinth is a unique plant that can absorb dissolved hazardous substances like cadmium and other metals. Establishing them in areas prone to such pollution will greatly lessen the negative consequences.
Precipitation, the ion exchange process, reverse osmosis, and coagulation are some chemical processes that aid in the treatment of water pollution. Individually, reusing, reducing, and recycling as much as possible will help to mitigate the effects of water contamination.
