Treating PFAS—Perfluoroalkyl and Polyfluoroalkyl Substances

Leachate and Industrial Water Solutions

Saltworks can help with PFAS problems, integrating solutions into existing or new wastewater processes. There is no single solution for PFAS-laden waters. We will study your problem and present you with options.

Perfluoroalkyls & Polyfluoroalkyls

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) are a group of man-made carbon-fluorine chemicals, widely used in many industrial and household products. PFAS “forever chemicals” do not naturally degrade. They are highly dangerous to human health and the environment.


The accumulation and treatment of PFAS is facing heavy scrutiny in a number of sectors including industrial, municipal, and waste management. PFAS are detected in many wastewaters, especially landfill leachate, due to their widespread uses in consumer and industrial products.

Treating PFAS

PFAS treatment systems need to be carefully engineered, with consideration of specific wastewater chemistry, co-contaminant removals, and the pros and the cons of different treatment options.
Alone, or together, there are multiple choices—including new advances—that need to considered to provide an optimal solution:

  • Granular activated carbon (GAC)
  • Ion-exchange (IX) resins
  • Evaporator Crystallizers such as SaltMaker
  • Nanofiltration (NF) or reverse osmosis (RO) such as XtremeRO/NF

Saltworks can help you to develop new water treatment systems or upgrade existing ones to treat PFAS. Our treatment professionals will help you assess the cost and performance of relevant options. Contact us. Challenge us.

Ultra High Pressure Reverse Osmosis for Landfill Leachate

Reverse osmosis (RO) is the best available technology to treat landfill leachate for surface discharge. Possible trace volatile organic compounds (VOCs) and ammonia emerging in the RO permeate can be removed with a polishing step to meet the highest discharge standards.

Biogas Digester

Anaerobic Digester Wastewater Management During Biogas Production

Digester wastewaters are by-products of biogas production in anaerobic digesters. They require treatment prior to disposal. To meet regulation compliance, treatment options range from minor interventions such as selective contaminant removal, to major interventions such as minimum and zero liquid discharge (MLD/ZLD).
