The City of Alma wastewater plant has been operating SSI’s PTFE coated 12” disc diffusers for almost one year with no problems. We have not had to perform  any maintenance on the diffusers and there has been no instances of membrane clogging whatsoever. The PTFE coated diffuser membranes have made all the differences in our aeration basin since installation and we are very satisfied with SSI’s product and would recommend to anyone.

We’re planning to check on  membranes later for  maintenance. We cannot believe that we have not had to clean them yet. Thank’s for making life easier for the operators at plant and have a great 2007.

Sincerely, yours
