Axine Water Technologies is expanding its leadership team to support its growth in industrial wastewater treatment of PFAS and other contaminants.

Regulation of PFAS chemicals continues to increase — here are some steps finishing operations can take to prepare.

EPA has issued guidance to states and POTWs on how it can use existing permit authorities to reduce PFAS in water discharges.   

The proposed new metal finishing standards to address PFAS is now being pushed back from August 2024 to December 2024. NASF is discussing with EPA staff the agency’s pending survey of the industry, which will likely be sent to finishing companies by April 2023.

NASF releases regulatory alert on EPA information collection request for PFAS wastewater discharge rule.

The NASF-AESF Foundation Research Board has selected a project on addressing the problem of PFAS and related chemicals in plating wastewater streams, studying PFAS destruction via electrooxidation and electrocoagulation.  Our last report described the results from experiments of EO with a Magnéli phase Ti₄O₇ anode on the degradation of eight perfluoroalkyl acids (PFAAs).  In this seven quarter report, we describe work to further explore how the degradation of different PFAAs are related to their molecular structures.

This article is based on a presentation given at NASF SUR/FIN 2022, in Rosemont, Illinois, in Session 6, Responses to PFAS / PFOA.  It follows the case study of three facilities’ conversion from PFAS-containing wetting agents to non-PFAS equivalents, eliminating PFAS and moving forward with a smaller and more sustainable environmental footprint.  The journey of conversion from PFAS-containing wetting agents in both chromic-sulfuric etch and hexavalent decorative plating tanks can be complicated and winding due to deep rooted standard industry practices, as well as state and federal regulations.  Outlined here is a clear course of action that led to eliminating PFAS from the facilities’ wetting agent strategies. 

The Department of Defense announced that it was temporarily stopping the incineration of PFAS-containing materials until it can issue appropriate disposal guidance.

Legislation was recently introduced again in Congress that would require EPA to issue wastewater discharge limits for PFAS for electroplating and metal finishing source categories.  Among other impacts, the measure would accelerate the PFAS rulemaking on which NASF is already working with EPA.
