SETE Energy Saudia has completed the installation of the SSI fine bubble aeration system at the Jubail WWTP in Saudi Arabia. Pictured below are the AFD350 fEPDM diffusers with PP piping system and SS hardware. SSI worked with SETE to select the proper materials for the job through our significant experience working in the Saudi market, having installed hundreds of thousands of diffusers in the Makkah/Jeddah region. The fluorinated membranes is designed to extend the lifetime of the diffuser and to reduce the frequency of cleaning.

Below is a photo of the installation in one of the tanks. SSI’s Service Manager will be on site shortly from the US to commission the system.

Congratulations to Sergei Belotelov, SSI’s representative in Ukraine, on the sale and successful installation and commissioning of the SSI fine bubble PTFE disc aeration system at Rubezhnoye Paper in Ukraine. Below are some photos of the installation which includes over 3000 AFD350 PTFE discs. This system was sold after the completion of a completitive pilot test and analysis of diffused aeration with other technologies by the Client’s consultant, CF Ingenerie of France. Congratulations to all on a job well done.

SSI continues to follow Redmon Engineering’s independent study of SSI AFD350 PTFE disc diffuser membranes installed at the Fox Metro WWTP in Elgin, Illinois (Chicago metro area). This study was funded by the Fox Metro Water Reclamation District and results have been shared with SSI.

After 2 years and 5 years of performance, the data have shown consistency in both SOTE and “as is” and “cleaned” headloss of the tested samples with “new” diffusers from the same batches.

Below is a photo of the 5 year old sample which tested out like “new”.

It is an outstanding result for PTFE, considering that according to many published studies, plain EPDM membranes lose 20% or more of their efficiency over a 5 year period.

SSI congratulates its New England representative WESCOR on a successful New England SEA show this January 22-25, 2012 at the Marriott Copley Square in Boston, Mass. On display were SSI PTFE coated disc diffusers, tube diffusers, and complete aeration systems. Pictured from L to R are Ryan Cournoyer, Bill Montanaro, Jr, Bill Montanaro, Sr and Steve Roach.

Join us! Stamford Scientific International will be exhibiting at IFAT Entsorga 2012. Come visit SSI’s booth in Hall A2, Stand no. 138.

The show runs from May 7th-11th 2012 and will be held in Munich Germany. We hope to see you there!

Thanks to the City of Thousand Oaks, California for the opportunity to retrofit their existing aeration system having EPDM membranes of another make with SSI PTFE disc diffuser membranes. This is a large project that is ongoing, however we can share with you some photos of some of the basins that have been completed to date. The Operator is very satisfied with the new membranes and is expecting to see a return on investment in the form of a longer membrane life with less change in physical properties of the membrane over time.

Thank you to Shupe and Associates and the City of North Little Rock for their recent order to replace existing ceramic diffuser elements with SSI PTFE retrofit membranes. These are SSI PTFE coated EPDM diffuser membranes, 9″ diameter, which are the same as are used in SSI AFD270-P diffusers. The site’s existing diffuser bodies and piping system were made by others.

Below are some photos of the installation.

Thank you to TICSA of Mexico for an outstanding job at the Tierra Negra WWTP where SSI Snappy Saddle tube diffusers model AFTS3100 were installed in 2010. Below are some photographs of the installation before and after commissioning. The installation went smoothly and rapidly and we have another satisfied client.
