King Fahad Causeway MBBR Sewage Treatment Plant
A complete MBBR sewage treatment plant serving both the Saudi and Bahraini sides of the King Fahad Causeway — 2 × 500 m³/day, meeting each country’s discharge standards.
Complete supply and installation of MBBR sewage treatment plants for both the Saudi and Bahraini sides of the causeway, meeting each country’s discharge standards with stable biological treatment under varying loads and automated PLC control with odour management.
The King Fahad Causeway is a 25 km sea-bridge between Al-Khobar and Al Jasra, managed by KFCA. FK & Partner Co. handled supply, installation, testing, and commissioning of the MBBR plant treating domestic wastewater from staff and administrative facilities on both sides; IE-Consult led the design.
A single plant had to serve facilities on both sides of an international border and satisfy two countries’ discharge standards, with stable performance under fluctuating hydraulic and organic loads.
- Two countries’ discharge standards
- Fluctuating hydraulic & organic loads
- Border-facility reliability
A treatment train sequenced to the contaminants.
Grit & grease pre-treatment protects the process; an MBBR biofilm reactor gives high-efficiency BOD/COD/TSS reduction resilient to load swings; sand filters and chemical disinfection finish for safe discharge; an odour unit and PLC auto-control complete the plant (2 × 500 m³/day).
