Containerized Oily-Water Treatment — Duba & Tabuk Bulk Plant

A rapidly deployed containerised plant treating oily water that seeped into a newly built sump at Duba Bulk Plant, to meet government limits before marine disposal.

Executive summary

When a new sump at Duba Bulk Plant seeped oily water into the excavation, FKP delivered a containerized modular plant — assembled in standard 40-foot containers for rapid deployment — to treat the industrial oily water safely for marine discharge.

A new 11 × 8 × 6.5 m sump built by Rawabi Butec experienced oily-water seepage ~3 m deep, needing an urgent compliant solution. IE-Consult proposed a containerised modular plant; Water Technology Company (W-Tech) assembled it in standard 40-ft containers for rapid deployment.

The challenge

Oily water seeping into a fresh excavation at ~3 m depth demanded an urgent, transportable treatment solution that meets government regulation before marine disposal.

Site & process constraints
  • Urgent response to active seepage
  • Government limits before marine disposal
  • Remote bulk-plant site
Engineering approach

A treatment train sequenced to the contaminants.

Gravity Oil-Water Separator → DAF → Sand Filter → Cartridge Filtration → Ultrafiltration

A gravity oil-water separator (3 × 50 m³/hr) takes the first cut, DAF removes suspended solids and residual oil, FRP sand filtration and cartridge filtration polish, and an ultrafiltration module (75 m³/hr) finishes — all assembled in three 40-ft containers for fast mobilisation.

Containerised for speed: standard 40-ft modules let the plant deploy fast to a remote site.
