Environment friendly ways to remove pollutants from water bodies

What is it about?

Industries around the world pollute water bodies with their wastes. Toxic chemical pollutants like dyes and heavy metals mix with clean water and make it unusable. This has led to a shortage of drinking water in many parts of the world. As a result, scientists have started to focus on ways for industries to remove pollutants from their wastewater. A popular method for this is adsorption. In this method, pollutants get adsorbed (or get attached) to the top layer of a solid material. The pollutants and the material are then removed. This article talks about “biosorbents,” which are essentially biological adsorbents. Many materials, including waste from farms and industries, are used as biosorbents. The authors discuss the benefits and drawbacks of using these materials to treat wastewater.

Why is it important?

Across the world, industries, farms, and cities are polluting clean water. Many of the pollutants released by them are toxic and can cause cancer and other disorders. Only about 3% of the ground water on the Earth is pure and fit for human consumption. The rise in water pollution is making this water unfit for use. As a result, millions of people may lose access to drinking water. This problem requires immediate attention and action. It is critical to develop effective methods of cleaning up water bodies. Biosorbents offer a simple and inexpensive way to clean wastewater. These are nontoxic, low cost, and biodegradable materials. They can even be combined with other materials. This allows us to improve their efficiency. KEY TAKEAWAY: There are many ecofriendly options for getting rid of water pollutants. One of these is biosorbents. These are both easily available and less expensive. Future research should focus on making these materials more practical for use.
