  • Patent number: 11807565
    Abstract: A method for remediating wastewater formed by water and per- and poly-fluoroalkyl substances (PFAS) using a wastewater treatment system that includes a collecting unit, a dewatering unit, a drying unit, and a baking unit. Wastewater provided to the collecting unit is dosed by adding a compound to the wastewater in an amount that is sufficient to cause the PFAS to separate from the water and to form a sludge. The sludge is dewatered with the dewatering from a first dryness level a second dryness level. The dewatered sludge is then dried in the drying unit from the first dryness level to a third dryness level. The dried sludge is then baked at a sufficiently high enough temperature that chemical bonds of at least a portion of the PFAS is destroyed.
