Despite the identified challenges, ECT2’s robust pretreatment of granular activated carbon (to remove co-contaminants) and a backwashable sand filter (to remove solids) relieved the challenges from the co-contaminants and TSS.
The pretreatment was followed by ECT2’s SORBIX™ PURE Ion Exchange Resin which provided the best total solution for the client. From concept to commissioning, the team was able to provide onsite services to help optimize flow and treatment efficiency. Through national standard testing for PFAS, ECT2’s applied solution was accurately measured. Compliance to the 70 ppt state-mandated discharge goals was met for all 100 million treated gallons.
ECT2’s SORBIX™ PURE ion exchange resin has a dual mechanism of adsorption resulting in smaller treatment vessels and more cost-effective treatment. The tail of a PFAS molecule adsorbs to the resin’s backbone (adsorption), and the head of the PFAS molecule is attracted to the resin’s ion exchange site (ion exchange). This combination of adsorption and ion exchange produces the rapid removal of PFAS while generating minimal waste.
As an ongoing project, ECT2’s team is continuing to work with textile firms in the southeast to clean up their legacy impacts with sustainability in mind.
