Shoalhaven City Council
foam fractionation technology (SAFF) remediating PFAS from leachate at Shoalhaven landfill

Location: Shoalhaven Council LGA, NSW, Australia

Installation date: November 2022

Client: Shoalhaven City Council

Site type: Landfill

Application: Leachate

Product: SAFF20®

Capacity: 200-240 m3/day (dependent upon leachate chemistry)

The Solution:

  • The objective of the project is to remove PFOS, PFHxS & PFOA from landfill leachate catchment water to below the Australian PFAS NEMP V2 (2020) drinking water criteria so Shoalhaven City Council can use treated leachate water in its recycled glass plant rather than valuable potable water reserved for the local community.
  • Water treated as of March 2023: 2,800,000L with zero contractual failures.

Treatment Results:

PFAS Series Feedwater Conc. (ng/l) Treated Water Results (ng/l) Treated Water Removal Percentage (1)
PFOS80<10100%
PFOA130<10100%
PFHxS150<10100%
Combined PFOS + PFHxS230<10100%
8:2-FTS<50<50-
PFDA<20<20-
PFNA<20<20-
6:2-FTS<50<50-
PFHpS<20<20-
PFHpA50<20100%

(1) Removal percentage (%R) is calculated by comparing treatment results to feed and/or laboratory LOR (10-20 ng/l), FTS (50 ng/l).
