Sewage Treatment Plant

Completed in 2012, ASRY’s sewage-treatment facility is Bahrain’s first to combine a reed-bed system with a Moving Bed Biofilm Reactor (MBBR). It treats up to 1,500 m³ of wastewater each day. After passing through the biofilm stage, residual sludge irrigates dedicated reed beds that absorb the remaining nutrients. The process uses no chemicals, runs quietly, gives off no odour, demands little upkeep and leaves nothing for landfill.

 Marine Sludge Treatment Plant

ASRY is the region’s first shipyard to recover sludge discharged by crude-oil tankers. A monitored programme of bioremediation converts the waste into about 2,000 tonnes of compost each year, which is subsequently used in landscaping around the yard.

 Grit Treatment Plant

To deliver clean surfaces before coating, the yard operates a high-capacity plant that grades and conditions fresh grit for both internal and external blasting work.
