Below is an aerial photo of the Makkah 1 South WWTP installed 5 years ago with SSI AFD270 diffusers, courtesy of Google Earth. This is a 250,000 m3/day (67 MGD) facility A20 process with biological phosphorus removal. There are multiple plants like this in the Jeddah/Makkah region. Most of them use SSI diffusers, and many using SSI PTFE coated EPDM diffusers. SSI was involved in the design of this project from the beginning, including Biowin simulation. The effluent quality is excellent and the aeration system runs smoothly.

EnvironQuip Ltda., SSI’s longtime distributor in Brazil, has successfully installed SSI PTFE disc diffusers in another dairy WWTP. This client, Mu-Mu Alimentos, is a well known Brazilian manufacturer of doce de leite, gelato, and milk. Many dairy wastewater treatment plants are turning to SSI PTFE diffusers due to their successful track record in this industry.

Congratulations to Smith Cameron, our representative in BC, Canada, for securing the Penticton WWTP project for SSI. The fine and coarse bubble diffusers have just been installed and commissioned. Below is a photo of the SSI Snappy Saddle system under test.

Alok Industries of India, a Textile facility, has replaced the membranes in a system installed by a competitor with SSI PTFE at their production facility. Attached are some photos of the plant with the new SSI PTFE disc diffuser membranes installed. The plant personnel tell us that they are thrilled with the upgrade. Note the membranes in these photos were made by SSI but the system components were made by others.

Drydon Equipment sold the Plover, Wisconsin Sewage Treatment Plant an SSI fine bubble disc aeration system which was installed this winter. The system will be started up in February, 2011. Congratulations to Drydon on another job well done.

Congratulations to Mick Heavner, PE of Clearwater, Inc. on the successful installation and commissioning of the coarse bubble aeration system at Ahoshkie, NC.

Congratulations to SSI Indiana representative H & T Systems, contractor Bowen Engineering and consulting engineer BLA Inc. on a successful installation of the new SSI PTFE retrievable fine bubble aeration system at Tell City, Indiana. The system features SSI model AFTS3100-PTFE with PTFE coated EPDM tube membranes. Below are some photos of the plant at commissioning. High quality components are used in every part of SSI systems, from virgin plastics to compression molded membranes, to SS components welded by ASME code welders.

In 2009, Pierce County (Tacoma) Washington installed 9000 SSI PTFE disc membranes at their 29 MGD WWTP as a replacement for plain EPDM disc membranes made by another well known American company.

Pierce County reports a .6 PSI drop in pressure across the entire system after installing the SSI PTFE Diffusers. The system pressure dropped from 9.8 to 9.2. They said that typically they need a 500 hp blowers and 1 or 2 150 hp blowers to meet the demand. So far they have only needed the 500 hp blower. He is very happy with the new diffusers and wants them in used in their future expansion.

Thank you Pierce County for your business and congratulations on the successful installation that is so typical of this product. And thanks to Bob Thurston of Correct Equipment, Inc., SSI’s representative in the Territory, for reporting this information.
