March 2018 Newsletter – POREFLON chosen for municipal wastewater treatment

March 13, 2018

Location: Americas, 2017

Goal: Stable, durable membrane fiber for MBR unit

Capacity:
760 m3/d (260 GPD)
MLSS average 15,000 mg/L

Result:
BOD 2 mg/L
TSS <3 mg/L

Situation

Cassette Type PhotosThe cassette unit pictured to the right is the type of membrane bioreactor (MBR) system that Sumitomo’s USA Water Processing Group was invited to install at a municipal wastewater treatment facility in the Americas last year.

The plant’s existing MBR system had operational problems surrounding the breakage of the fiber membranes due to extreme conditions in the waste stream. This particular wastewater treatment plant had a standard throughput of 760 m3/d with an average MLSS of 15,000 mg/L.

Results

The primary difference in the Sumitomo MBR was the POREFLON PTFE hollow-fiber membrane — developed, tested and proven for its durability in extreme operating conditions. Under this particularly challenging situation, the PTFE hollow-fiber membrane module performed stably and delivered a good treatment standard — BOD was 2 mg/lL and TSS was less than 3 mg/L — during its testing phase and beyond.

The POREFLON PTFE Membrane Module continues in operation today, proving its value for high performance in extreme conditions.

PTFE hollow-fiber membranes were made to withstand extreme situations at a high performance standard.

With a very broad application range, even beyond challenges in municipal wastewater, the product is also an excellent choice for treatment of:

  • leachate at waste disposal sites
  • wastewater at oil refineries
  • wastewater from heavy industrial facilities, e.g. fabric dyeing and metal cutting
  • pharmaceutical manufacturing waste streams
  • industrial plating and scrubber drainage

POREFLON PTFE membrane modules stand up to waste water streams containing high oil content with stable performance, easy maintenance, and long life. A proven problem solver.
