Ion exchange is widely used in the food and beverage industry, hydrometallurgy, metals finishing, chemical, petrochemical, pharmaceutical technology, sugar and sweetener production, ground- and potable-water treatment, nuclear, softening, industrial water treatment, semiconductor, power, and many other industries.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
Technological advancements in ion-exchange membranes and electrodialysis systems has enabled high efficiency treatment of flue-gas desulfurization wastewater to meet recent EPA discharge limits. [19] The treatment approach is similar for other highly scaling industrial wastewaters.
Selective electrodialysis uses ion selective exchange membranes to concentrate only some ions, whereas other species remain in the diluted channel. Selective electrodialysis is usually done by employing monovalent anion and/or cation exchange membranes, that only allows migration of monovalent anion or cations, respectively.
“While our success in destroying PFAS-impacted waste streams like Aqueous Film-Forming Foam (“AFFF”) at commercial scale has solidified AirSCWO as a reliable solution for PFAS disposal, we are now focused on applying our technology to meet the DoD’s most pressing PFAS treatment challenges,” said Chris Gannon, CEO of 374Water.
