The IFAS system will achieve BOD reduction, nitrification and denitrification, producing effluent suitable for reuse and irrigation applications.
Along with the process design, Headworks BIO will supply the core components of the IFAS system, including media, aeration grids, and media retention screens.
Headworks BIO will partner with Saudi contractor Wetico to construct the new 10 000 m3/day sewage treatment plant.
“We had to consider many factors when selecting a technology that would be suitable for our specific application,” said Dr Ahmed Khalaf Abdel-Lah, vice president of KSU. “One of the key challenges was to address the seasonal variation in occupancy levels on campus during the summer holidays that causes low flow or no flow for extended periods of time.”
KSU also required an extremely compact plant so that its presence on campus would have minimal visual impact. The four treatment reactors will have a total footprint of 144 m2.
Construction is already underway, with start-up expected later this year.
