Makkah 1 South WWTP -Aerial Photo
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.
