In this YouTube video “How Do Wastewater Treatment Facilities Work?” r treatment is addressed.
Massive sewage flows through American cities can lead to massive water accumulating at water treatment plants. The wastewater flows through massive bar screens, which are used to filter solid materials such as toilet wipes or plastic items away from the wastewater. When the wastewater is processed, it is passed through the filter chamber. Its slow rate of the machine guarantees that there are fewer waste particles and the water remains more homogeneous.
The wastewater is further filtered by clarifiers making use of flow velocity. This is a way of reduction of solid contaminants to 10 micrometers. The liquid is then transferred into the aeration reservoir, where return activated sludge eliminates organic matter. The wastewater is now suitable for use following its passage through the second clarifier. This is followed by the disinfection process which utilizes chlorine, ozone, or UV light to purify the water even more. Each method for disinfection has its advantages and disadvantages. After disinfection, the affected water is pumped back for general usage in the homes.
