Due to rapid growth in cities, demand for water has increased dramatically. To meet the demand for water, groundwater resources are being exploited at a rate that is depleting at a very rapid rate. Second, there has been no adequate recharge of groundwater resources to maintain the continuous supply of groundwater. Therefore, we have to see that the water resources already present are maintained and can also be increased by other options. Therefore, water resources must be maintained and managed well.
The future of our water resources depends on the development of water resources. Therefore, the reuse of water has become the need of the hour. One option could be the use of treated wastewater effluents. Cities and cities generate huge amounts of wastewater. This, when discharged directly onto open ground, is causing considerable contamination of water, soil and air. Wastewater may have to be treated first in sewage treatment plants, which in turn will produce large amounts of effluent.
The problem is how to make good use of effluents, which not only go to waste, but also cause environmental pollution. Now, the question is, by what means effluents from wastewater treatment plants can be converted into reasonably pure water. The floor has been known as a major water cleaner. It has the capacity to act as a physical, chemical and biological filter.
