Stage One of Wastewater Treatment
Wastewater comes from many places, including rainwater. The water contains everything from feces and urine to sticks and other debris. It’s estimated that 35 percent of wastewater is made from solid objects.
Stage Two of Wastewater Treatment
The water is free from sludge and other solids, but it’s nowhere near clean. Other contaminants must be removed.
Final Removal of Remaining Contaminants
Wastewater treatment plants use several combinations of methods to remove the remaining contaminants in the water. The most common method is to run the water through a sand filtration system.

1. Benefits environment
Since all the water waste is released in natural water reservoirs such as lakes and rivers, the water gets contaminated. This polluted water is consumed by fishes, crops, and animals. Also, the polluted water is evaporated and ultimately the rainwater is also nothing but polluted water.
2. Recycled water
Since factories and industries require a huge amount of water every day for different processes, water recycling is the best solution. Any water waste treated by plants is pure enough to be utilized again. This process saves hundreds of liters of water.
3. Energy production
The sludge collected during the wastewater treatment process contains a large amount of biodegradable material. These materials can be used to generate electricity and other energy. The energy generated here can be used in wastewater treatment plants making it self-sustainable.
