Treatment Technologies for PFAS in Industrial Water Perfluoalkyl chemicals are organic chemicals whose hydrogen atoms have been replaced by fluorine. Polyfluoroalkyls have had many of the hydrogens replaced by fluorine. More than 4,000 perfluorinated and polyfluorinated substances (PFAS) have been produced since they were developed in the 1940s. More than 1,000 are listed in the […]Continue Reading

Most municipalities throughout the United States add chlorine to the water supply to treat the presence of germs and general microbial contaminants in the water. While this is considered a great benefit for general water safety, chlorine also has the side effect of changing the taste and odor of the water that you drink. What […]Continue Reading

Public drinking water supplies in the United States have been chlorinated since 1908, based on a study published in 1894 that determined that the addition of chlorine to water rendered it “germ free”. Today – over a hundred years later – chlorine has been adopted by the vast majority of municipalities across the country as […]Continue Reading

Multipure’s Solid Carbon Block filters utilize multiple filtration actions, combining mechanical filtration, electrokinetic adsorption, and physiochemical adsorption to provide the most effective contaminant reduction possible. When water streams into and through a Multipure carbon block filter, contaminants initially undergo electrokinetic adsorption as the water passes the outer prefilter. The prefilter develops a positive molecular charge […]Continue Reading

A recent study by the University of Illinois found that karst aquifers – groundwater ecosystems made up of creviced carbonate rock, and that make up one-quarter of global drinking water sources – are now contaminated with microplastic particles. Examining 17 groundwater samples from areas near the St. Louis metropolitan area and rural northwestern Illinois, researchers […]Continue Reading

Despite increasing reports of widespread microplastic pollution – in drinking water, in seawater, and in food supplies – many studies are still being conducted to determine the quantifiable dangers of microplastics. Microplastics are defined as any piece of plastic measuring between five millimeters (5 mm) and one micrometer (1 μm) in size. Plastics smaller than […]Continue Reading

A 2018 study by Orb Media, a nonprofit investigative journalism organization, examined eleven different bottled water brands across the world, finding that all of them contained some degree of microplastic contamination. Using a special dye that binds to plastic, the researchers used a special light to highlight the dyed particles in the water samples, and […]Continue Reading

About 10,000 pharmaceuticals with about 3,000 active ingredients are approved and marketed in the U.S. These and their reaction byproducts, reactants and solvents can be present in waste streams that require treatment prior to direct or indirect discharges. Pharmaceutical production is a major portion of the chemicals manufacturing industry — in value and product diversity, […]Continue Reading
