PFOA and PFOS Removal by Membrane and Filtration Treatment

Posted by Anthony DeLoach, President on Aug 10, 2023 2:04:26 PM

In recent years, PFOA and PFOS, commonly known as "forever chemicals," have raised concerns among municipalities, food and beverage industries, and commercial facilities in the USA and around the globe. These synthetic chemicals, which never break down and pose significant health risks, have been detected in water, food supplies, and even bottled purified water. As new EPA regulations take effect in 2024, industries are searching for effective and cost-efficient methods to remove these hazardous substances from their water supply. Fortunately, advanced water purification technologies such as microfiltration, ultrafiltration, and reverse osmosis can address these challenges.

Regulations for PFOA and PFOS Chemicals

Posted by Anthony DeLoach, President on Jul 20, 2023 11:30:00 AM

PFOA and PFOS are man-made chemicals used in various products to simplify life. 

Forever chemicals, also known as synthetic chemicals called PFAS, have gained recognition. Scientists created these chemicals to make products resistant to water, stains, and sticking. The United States initially utilized them in the 1950s.

DuPont introduced Teflon in the 1950s to help Americans have nonstick cookware and make their lives easier. Americans and people from other countries liked this new improvement and soon used these substances in many different products.

These chemicals are resistant to water and lipids, so they don't break down and last a long time in the environment.

Over time, companies have used these chemicals in manufacturing various products, such as firefighting foam, food packaging, and cosmetics. As a result, these chemicals have entered the air, water, soil, and food production. They discontinued the use of PFAS and their other compounds in the mid-1970s.

People believe that contamination has affected more than 7000 metric tons of Fluorochemicals. PFOAs and PFOS, which can cause various health problems, have exposed many Americans and people in the USA.

PFOA chemicals contaminated 1% of public drinking water supply systems in 2016. The EPA did not regulate safe levels of PFOA and PFOS in drinking water systems for many years.

Advancements in Per and Polyfluorinated Substances  Removal Technology

Posted by Anthony DeLoach, President on Dec 14, 2021 1:00:00 PM

Per- and polyfluorinated substances (PFAS), known as "forever chemicals," have long been utilized in various consumer products due to their exceptional properties.

However, the challenge lies in effectively treating or eliminating PFAS once they enter the environment or water supply. This blog will focus on the technological advancements in removing PFAS and perfluorooctanoic acids (PFOAs) from water sources. By exploring different treatment methods, such as activated carbon absorption, ion exchange resins, and reverse osmosis, and simply avoiding PFOA and PFOS, we can better understand the available options for mitigating these persistent chemicals in water.

Activated Carbon Absorption

One of the earliest technologies employed for PFAS removal is activated carbon absorption. This method involves the use of specially treated carbon materials that effectively adsorb PFAS compounds from water sources. The activated carbon's large surface area and porous structure allow it to trap and retain PFAS molecules. This technology has proven effective in removing PFAS, including PFOAs, from drinking water and environmental sources. However, periodic treatment and regeneration of the activated carbon are necessary to maintain its efficacy.
