What substances are greatly reduced by lime coagulation, mixed media filtration, and activated carbon filtration?

Lime coagulation, mixed media filtration, and activated carbon filtration are processes used primarily in water treatment to improve water quality by removing various contaminants. Among these, the processes are particularly effective in reducing EPA priority pollutants, which include a range of toxic substances that the Environmental Protection Agency has identified as harmful to human health and the environment.

Lime coagulation works by adjusting the pH of the water to promote the precipitation of certain contaminants, including a variety of heavy metals and other soluble substances. This process can lead to the formation of flocs that can then be removed from the water through filtration.

Mixed media filtration utilizes different types of filtration media to capture and retain contaminants, enhancing the removal efficiency of various particles and chemicals. This method can remove suspended solids and a range of pollutants, contributing to lower concentrations of priority pollutants.

Activated carbon filtration is particularly well-regarded for its capacity to adsorb organic compounds and chemicals from water, effectively reducing concentrations of many EPA priority pollutants, including volatile organic compounds (VOCs) and some pesticides, which can be challenging to remove through other treatment methods.

Overall, when these three processes are applied together, they work synergistically to reduce a wide array of pollutants, making them effective for ensuring safe drinking water and compliance with
