Why does filtration typically follow powdered activated carbon (PAC) addition in a water treatment plant?

PAC enhances the taste of water
PAC creates turbidity which must be removed before distribution
PAC improves flocculation efficiency
PAC helps in reducing microbial counts

The correct answer is: PAC creates turbidity which must be removed before distribution

Filtration typically follows the addition of powdered activated carbon (PAC) in a water treatment plant because PAC can introduce turbidity to the water. When PAC is added, it can cause fine particles to be suspended, which may lead to an increase in cloudiness. This turbidity must be effectively removed through filtration before the water is deemed safe for distribution and consumption. Although PAC is beneficial in adsorbing organic compounds and improving taste, the primary concern after its addition is the management of turbidity. Proper filtration processes are essential to ensure that any particulate matter introduced does not adversely affect the water quality and clarity. Therefore, addressing turbidity through filtration is a crucial step in the treatment process after PAC addition.
