Desalcott’s Point Lisas seawater reverse osmosis plant in Trinidad, West Indies, is nearing completion on its sixth expansion since it was commissioned in 2002.

The expansion consists of the addition of a new 914 mm intake header, three new 483 mm pipelines from the intake to the plant, an upgrade to the flocculation/sedimentation basins, a new clearwell pump, one new seawater reverse osmosis train, two new brackish water reverse osmosis trains, a new 915 mm permeate header, a new product delivery station and modifications to the chemical feed systems.
The next planned expansion is scheduled for June 2015 and will include adding more reverse osmosis capacity along with a Pall micro filtration pretreatment system, following three years of pilot studies.
The plant is the largest seawater desalination plant in the western hemisphere. according to Desalcott.
