What People Are Saying

We have had the SSI Aeration AFC coarse cap diffusers installed in our two 450,000 gallon sludge holding basins for nearly five years and we have never had a problem with them. We also see adequate mixing and desired performance. The basins are inspected periodically and we have not had to replace any of the modules to date in our wastewater treatment system.

What People Are Saying

We were facing the possibility of having to build side stream wastewater treatment facilities to keep up with the demand-and this would have been extremely expensive. But because the SSI PTFE fine bubble diffuser is so effective, we didn’t need to do that project, and we’re handling more water than ever before.

SSI Aeration takes its mission of providing aeration systems for industrial and municipal wastewater treatment plants with great seriousness. As the years have gone by, we realized there was a way we could achieve our mission and do more for the community. At our Poughkeepsie Headquarters, we have taken this idea in a surprising direction.

Todd Ritter, of the SSI Executive Team, explains: “we discovered that the precision fabrication, manufacturing and shipping we require could be provided locally.
