Granular Activated Carbon for PFAS Removal in Municipal Wastewater: A Rapid Small-Scale Column Test Study.

Recently, we at PURESTAR, have been investigating the application of GAC in the removal of PFAS from municipal wastewater, whereby in this post, we will share what we learnt from our pilot column scale work testing on the removal of PFAS by GAC.

Assessing the Efficiency of Granular Activated Carbon in the   Removal of PFAS

Per- and polyfluoroalkyl substances (PFAS) are a group of manufactured chemicals that have been used in industry and consumer products since the 1950s. Such compounds are often hazardous to both human health and the environment, hence a need to develop efficient means of eliminating them from waste water. One approach to accomplish this is with   granular activated carbon filter .

GAC is a very porous material that can trap pollutants, including PFAS, from water. In our study we evaluated the effectiveness of GAC to extract PFAS from municipal wastewater. Results indicated that GAC was effective for the attenuation of PFASs in water, suggesting that GAC could be considered as a negative PFAS remediation option.

Pilot-Scale Testing of GAC in Municipal Waste Water Treatment Type of water 511

To evaluate GAC removal performance of PFAS, small-scale GAC column tests (municipal wastewater spiked with PFAS) were carried out. The experiments were developed to replicate real conditions, and to ascertain the efficiency of GAC at collecting PFAS in the water.

Significant removal of PFASs was achieved in the water after crossing the  granular activated carbon water filter  columns during the experiments. This suggests that GAC is a suitable treatment to eliminate PFAS in municipal wastewater as a measure to protect public health and the environment.

One of the major benefits of GAC for PFAS treatment is that it works quickly. GAC is the fast tool to adsorb PFAS in water treatment practice and is an approach to solve PFAS pollution.

We believe in the efficiency of GAC to decrease PFAS in water levels in a fast and efficient manner offering a fast solution for removal of such hazardous chemicals. This quick look at GAC performance may indicate it as a candidate for implementation in municipal waste water treatment plants to safeguard water quality and public health.

Application of GAC to PFAS Contamination

PFAS pollution is an issue increasingly facing communities globally. Such toxic substances are resistant in the environment and may bio-accumulate in water bodies, posing a threat to human health and ecosystem. With Granular Activated Carbon we can remove PFAS and keep our water systems safe.

Otherwisewe recommend the granular activated carbon, the purer the better.}; GAC is a economical insitu method to remove PFAS in wastewater so we have the safety and clean water source as well. By introducing GAC treatment into municipal wastewater facilities, we have prevented PFAS from discharging into our water and eliminated potential human health effects due to PFAS.

Research highlights successes of GAC for PFAS in wastewater

4 Conclusions Overall, our study shows a promising application of GACs for PFAS removal in MWTPs. GAC was effective at adsorption of PFAS in water, this study offered the straightforward and efficiency measure in treating water contaminated by PFAS.

As we performed small scale tests to evaluate the efficacy of  granular activated carbon  we could see that, GAC has rapid removal efficiency of PFAS from contaminated water. This demonstrates the value of GAC as an asset to municipal wastewater treatment plants concerned with safeguarding water quality and public health.

In summary, our findings highlight the urgent need to develop effective mitigation strategies for PFAS discharges to wastewater. We can protect our water supplies and clean up our environment for generations to come with Granular Activated Carbon.
