PFOS-PFOA & emerging contaminant treatment

 

Waterform deliver turnkey Environmental Contaminant Treatment solutions for industry & Government institutions that provide verified performance & regulatory compliance with the Barrier-ECT™ systems.

No two water bodies are exactly the same. And no two pollution incidents are the same. Waterform takes a responsible approach to working with our clients to control, remove or re-mediate the impact of pollution. Some areas of specialist advice we can help you with are:

  • PFAS/PFC’s – short chain (such as  perfluorohexanoic acid (PFHxA) and perfluorobutanesulfonic acid (PFBS) and long chain varites (Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Waterform has built and operated specialist treatment facilities for major fire fighting Authorities and supplied equipment for Air Force facilities.
  • N-nitrosodimethylamine (NDMA)
  • Taste and odor-causing compounds (eg. MIB and geosmin)
  • Pharmaceuticals and personal care products (PPCPs)
  • Pesticides and herbicides.
  • 1,4-Dioxane.
  • Fuels and fuel additives (eg. MTBE and BTEX)
  • VOCs (eg. PCE and TCE)
  • Endocrine disruptor chemicals (EDCs)

Waterform Technologies is able to custom engineer and build a plant that may incorporate Advanced Oxidation (ozone/BAC – UV/H202- or others), along with controlled membrane separation and rigorous online monitoring to deliver best practise treatment with the Barrier-ECT™ system.

We operate in the confidence of our clients understanding that such projects require discretion & strict communication protocols, whilst delivering permanent outcomes.

 

Waterform were the only company really prepared to work through the detail, take engineering responsibility & work with all stakeholders over many months of exhausting meetings to deliver a site recycled water plant that met the strictest requirements for water quality including PFOS / PFOA control.

Waterform carried out extensive bench testing of contaminated groundwater, surface water and creek discharge water from a major fire training facility. Our studies using ozone/BAC+UF resulted in a stable efficient reduction of the following tested inorganic toxic compounds by over 99.9%

PFOS
PFOA
Fluorotelomer sulfonate
Fluorotelomer sulfonate
PFOSA
N-Me-FOSA
N-Et-FOSA
N-Me-FOSE
N-Et-FOSE
PFBS
PFHxS
PFDcS
PFHxA
PFHpA
PFNA
PFDcA
PFUnA
PFDoA
PFTriA
PFTeA

The strong fluorine-carbon bond and low vapor pressure makes PFOA/PFOS resistant to a number of conventional water treatment technologies, including:

• Direct Oxidation
• Biodegradation
• Air Stripping & Vapor Extraction
• Direct Photolysis (UV)

Recent publications have discussed some bench scale success with degradation or destruction using advanced oxidation and enhanced photochemical methods. However, water treatment methods ultimately must be practical and achieve treatment goals.
Waterform has selected a particular Granular Activated Carbon as the primary method to remove the contaminants of concern with pre-treatment including ozone oxidation to break down organic constituents into more readily removable forms. We have based our study on research undertaken by DuPont USA in 2009 surrounding affordable PFOS / PFOA removal options for municipalities faced with tighter EPA regulations, aimed at establishing the viability of treatment options apart from nanofiltration / reverse osmosis (NF / RO) membranes.

Of critical important to any successful ECT removal project, is the ability to allow for any other constituents in the water (particularly surface water!) such at TOC that will have a very negative impact on the efficacy and lifetime of the selected PFAS removal technology.

By trusting Waterform with your next Environmental remediation project, you know you are in safe hands.
