Sanitary Wastewater Treatment Plant BOO — Tanajib Marine

A build-own-operate MBR sanitary plant treating tanker-delivered domestic wastewater from the Tanajib Marine facilities — 5,400 m³/day, fully PLC-operated with 24/7 monitoring.

Executive summary

An upgrade to the existing unit, receiving tanker-truck domestic wastewater from Tanajib Marine Facilities and treating 5,400 m³/day to discharge standard via MBR. FKP delivered all civil and mechanical works, treated-water and sludge storage, and drying beds, running on PLC with 24/7 monitoring.

Upgrading the existing unit, FK & Partner Co. delivered all civil and mechanical works, treated-water and sludge storage tanks, and sludge drying beds, with five 120 kW generators and a synchronization switchboard; IE-Consult led the design.

The challenge

Tanker-delivered domestic wastewater from a remote marine terminal had to be treated to discharge standard reliably and autonomously, on a long 2022–2028 operating term.

Site & process constraints
  • Tanker-fed influent, variable load
  • Remote marine terminal — autonomous run
  • Long 6-year operating term
Engineering approach

A treatment train sequenced to the contaminants.

Screening → Grit & Grease Trap → Aeration → MBR Filtration → Sludge Drying Beds

Screening and a grit & grease trap pre-treat the influent; an MBR package provides biological treatment and membrane filtration to discharge standard; sludge drying beds dewater biosolids; the plant runs on PLC with 24/7 online monitoring, backed by five 120 kW generators.

Power autonomy: five synchronised 120 kW generators keep a remote plant running.
