XtremeUF ceramic ultrafiltration removes oils, grease, precipitated by-products, particulate, microbes, and suspended solids.
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 molecules are detected in many wastewaters, owing to their widespread uses in consumer and industrial products. Examples of waters containing PFAS include landfill leachate and aqueous film-forming foam stockpiles.
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:
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.

Treating Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) Contaminated Wastewater and Landfill Leachate
PFAS chemicals are often referred to as “forever chemicals” since they do not naturally degrade. PFAS are detected in wastewaters and landfill leachate due to their widespread uses in consumer and industrial products. They have made their way into some water supplies.
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.
Saltworks has started commissioning what we believe is a first-of-its-kind plant, with much customer interest. The membrane concentrator makes extensive use of reverse osmosis – turbocharged.
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).
