Work Performed

ASDR mobilized five (5) containerized wastewater treatment modules (20-foot ISO containers) for this project:  a caustic soda metering unit, a coagulant metering unit, a flocculant metering unit, a caustic soda storage unit and an electrical room. ASDR also provided a floating barge fitted with a 100-HP submersible pump to carry out the dewatering and dry maintenance project. Geotubes®* were deployed to collect and filter the sludge generated by the water treatment process.
