How To Get Rid Of PFAS And PFOS In Drinking Water

PFAS, or PFOS chemicals, have worried authorities and many people in the United States in recent years. The Environmental Working Group estimates that PFAS chemicals are present in about 1,500 drinking water systems, on which nearly 110 million people in the United States depend. 

PFAS chemicals are now a reality after homeowners received reports of high PFOS levels in their drinking water. Due to the serious health concerns associated with PFAS, it is important to know the best way to eliminate them from drinking water. Let’s discuss how to remove PFAS in water.

Reviews on PFAS Chemicals

PFAS is a family that includes many chemicals, but PFOS and PFOA are the most common. They are used in industry for their superior properties including water, grease, and oil repellent. Unfortunately, PFAS chemicals do not degrade, so they remain in the environment for a long time. In addition, exposure to these chemicals can have adverse effects on human health.

Methods for removing PFAS in water

1. Activated carbon treatment

This treatment process uses activated carbon to remove PFAS in water due to its effective adsorption properties. Adsorption involves the accumulation of substances at the liquid-solid interface.

2. Granulated Activated Carbon (GAC)

GAC treatment uses activated carbon in granular form, with PFAS substances attached to small pieces of carbon when water flows. This is effective if you remove the particles in the drinking water before it passes through the grains in filter mode.

GAC works well in removing long-chain PFAS substances but is not as effective in absorbing short-chain substances.

3. Activated Charcoal Powder (PAC)

Activated carbon in PAC processing is in powder form and PFAS chemicals adhere to its surface. However, due to its small size, you cannot use filter mode with this method. Instead, after adding activated charcoal to the water, you will need to add another particle to remove it. This extra step makes the process uneconomical and ineffective in removing PFAS.
