  • Molded EPDM membranes have tight wall thickness tolerances, a long and strong track record, and exhibit even air distribution and minimal shrinkage over time.
  • Patented PTFE membranes prolong efficiency, reduce plasticizer extraction, prevent membrane hardening, and limit dynamic changes, thereby reducing whole life costs.
  • Complete product line: 9” and 12” disc diffuser – create the system that fits your needs and budget.
  • Piping system integrity – thicker wall pipe and double anchors for fewer breakages.
  • SSI PODs connection is factory assembled to lower on-site labor costs, with shortest tank down time.
  • Grommet connection is easy to ship, move, and install on site. Affordable, tried and tested over 15 years.
  • Quick connect saddle allows installation with just a quarter turn of the diffuser and features an integral seal to ensure a leak-free connection. Allows membrane removal without disconnecting diffuser from the pipe.
  • Comprehensive design service and after sales support – our full drafting department works with you through design and calculation to simulation and installation.

“SSI went above and beyond our expectations. We couldn’t have been more satisfied with their products and their commitment to customer satisfaction. We look forward to working with them in the future.”

-Jerry Pressley, Fort Worth Water Department's Operations and Maintenance Superintendent.

“While I have been reluctant to attribute all our treatment plant improvements to the diffuser replacement, I think we all here think there has been a major difference in treatment plant performance. We had record low effluent turbidities in November and December and excellent nitrogen and ammonia numbers. I know we’ll all sleep better knowing that” -Chuck Rogers, Superintendent, Thousand Oaks, CA.
