HS-ACCCoal-Based Activated CarbonWhat is HS-ACCHydrosil’s HS-ACC is a highly active granular activated carbon (GAC) manufactured from select grades of coal. Hydrosil’s HS-ACC is designed for liquid phase applications. The coal-based carbon is typically used in portable water purification, wastewater treatment, industrial air purification, chemical purification, and the food and beverage industry. Coal-based activated carbon is known best for its’ combination of micro, meso, and macro pore structure. With a variety of pore structure the material is capable of removing a wide range of molecular weights. HS-ACC is NSF/ANSI/CAN 61 certified for potable water use. Where is HS-ACC UsedHS-ACC is commonly used in oil and gas refineries, municipal drinking water purification, and industrial pollution control. Industrial projects that use HS-ACC include groundwater treatment, stormwater run-off treatment, reverse osmosis systems, and removal of dissolved organics. HS-ACC, coal based activated carbon, is being used in combination with HS-PF for removal of per- and poly-fluorinated alkyl substances (PFAS). Granular activated carbon is one of the most well known technologies for removal of PFAS compounds through adsorption. What is Activated CarbonActivated carbon commonly referred to as activated charcoal is a a highly porous material used to remove pollutants from contaminated liquid and gas streams. Activated carbon is derived from a variety of raw materials such as coconut, wood, coal (bituminous, anthracite, sub-bituminous, and lignite), peat, and bamboo. Each raw material has unique properties which effect the resulting pore structure, carbon content, and ash content, which are important characteristics when removing a contaminant of concern. The material is used in remediation, medical, and industrial applications where adsorption is required. Activated carbon has strong physical adsorption properties known as London Dispersion Forces which is a Van der Waals Force. The attraction between the activated carbon and the pollutant are highly dependent on the vapour pressure of the adsorbing molecules. Activated carbon is often altered or impregnated by chemicals to enhance the surface area of the carbon. When the carbon is chemically altered the bonds are much stronger than London Dispersion Forces. Chemicals often impregnated on activated carbon include potassium hydroxide, phosphoric acid, or sulfur. With the addition of chemicals the activated carbon will have an affinity for select compounds such acidic or basic pollutants.

HS-PFLiquid Phase, PFAS/PFOA OrganoclayHydrosil’s HS-PF is designed to remove per- and polyfluoroalkyl substances (PFAS). The media is selective for removing PFAS (PFOA, PFOS, FTCA, FTSA, FTOH). Based on the application, flow, concentration of the pollutants, granular activated carbon (GAC) or resin may be used to remove contaminates to non-detectable limits. Hydrosil’s HS-PF is an economical and efficient remediation process which removes both long and short chain perfluoroalkyl carbolic acids (PFCAs). These emerging pollutants are commonly found in ground water from manufacturing facilities such as chemical, textiles, metal coating, automotive, as well as airports and air force bases. Testing has shown that PFAS can be adsorbed into the inter-layer structure of the material for complete PFAS removal including PFOS and PFOA. What is PFASPer- and poly-fluorinate alkyl substances are both known as “PFAS” or the “Forever Chemicals”. PFAS is grouped into polymers and non-polymers. Both of these are man-made chemicals have been manufactured for centuries in food packaging, stain repellents, textiles, fire-fighting foam, cleaning products, and military training equipment. PFAS chemicals are beginning to be phased out in the United States in order to eliminate the use of PFOA contamination. PFOA and PFOS is still be manufactured internationally and used in consumer products. The unregulated PFAS compound is also known as “GenX” to the large American chemical company that use it in manufacturing process. Due to the unique molecular structure of PFAS—it is extremely difficult to break it down. Several water treatment processes are resistant to removing PFAS; Hydrosil’s HS-PF works to remove PFAS by means of ion exchange. Ion exchange is used to remove both short and long chain PFAS.

Industrial projects that use HS-ACR include groundwater treatment, stormwater run-off treatment, and removal of dissolved organics. What is Reactivated CarbonReactivated carbon is a cost-effective alternative to virgin activated carbon. After the activated carbon is spent, the adsorbed organic compounds are destroyed via thermal treatment allowing the activated carbon to be used again. To reactivate carbon, the activated carbon is heated to high temperatures near 900°C which allows the organics that were adsorbed to be released from the pore structure. Once the organics are removed from the activated carbon pore structure the carbon is ready to be used again. The regeneration of activated carbon does result in a small loss of the activated carbons’ adsorption capacity. What is Activated CarbonActivated carbon commonly referred to as activated charcoal is a highly porous material used to remove pollutants from contaminated liquid and gas streams. Activated carbon is derived from a variety of raw materials such as coconut, wood, coal (bituminous, anthracite, sub-bituminous, and lignite), peat, and bamboo. Each raw material has unique properties which effect the resulting pore structure, carbon content, and ash content, which are important characteristics when removing a contaminant of concern. The material is used in remediation, medical, and industrial applications where adsorption is required. Activated carbon has strong physical adsorption properties known as London Dispersion Forces which is a Van der Waals Force. The attraction between the activated carbon and the pollutant are highly dependent on the vapor pressure of the adsorbing molecules. Activated carbon is often altered or impregnated by chemicals to enhance the surface area of the carbon. When the carbon is chemically altered the bonds are much stronger than London Dispersion Forces. Chemicals often impregnated on activated carbon include potassium hydroxide, phosphoric acid, or sulfur. With the addition of chemicals the activated carbon will have an affinity for select compounds such acidic or basic pollutants.

Both medias are impregnated with potassium permanganate (KMnO4) which oxidizes acid gases and odors. The HS-600 is a harder material than the HS-400; Therefore, the HS-600 will result in insignificant dusting. Depending on the application, Hydrosil will suggest either the HS-600 or HS-400. What is Potassium Permanganate?Potassium permanganate (chemical formula KMnO4) similar to sodium permanganate is a crystalline purple solid that dissolves in water.

The HS-100 is found in aquariums, residential drinking water filtration, wastewater treatment, stormwater treatment, mining trailing ponds, and agriculture industry. The HS-100 product is NSF 61 Certified for drinking water applications. What is Zeolite?There are roughly 40 types of natural occurring zeolites in the world. Natural zeolites are formed from sedimentary rocks or volcanoes which are essentially hydrated aluminosilicate minerals. There are 150 plus types of synthetic zeolites which are artificially made for specific purposes. Synthetic zeolites are manufactured to have uniform structure. Zeolites are hard solids which have high melting points. The material is unreactive and made with naturally occurring minerals. Zeolites are used in a variety of ways including water softeners, pet litter, catalysts, concrete production, and remediation. Understanding Ammonia/AmmoniumAmmonia in water exists as ammonia (NH3) and ammonium (NH4+). Depending on the pH and the chemistry of the water, the equilibrium and the presence of ammonia and ammonium will vary in your water. With a neutral pH and typical environments, most ammonia occurs as NH4+. As temperatures increase and the pH in the water changes the amount of NH4+ will decrease and the concentration of NH3 will increase. Typically when testing is completely on a contaminated water source, the total presence of free ammonia (both NH3 and NH4+) are accounted for. | ||
