Aquatech Recently Provided Membrane Desalination Solution to LNG Refinery

Aquatech recently completed a project for Sabine Pass, one of the largest LNG refineries in the United States. The client required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export. The client decided that a reverse osmosis (RO) desalination solution, followed by a demineralization step, would best suit their intended system designed to operate on single pass RO feed water. Since single pass RO water is a challenging application for conventional electrodeionization (EDI) systems, the customer carefully evaluated options for RO permeate polishing. Our Fractional EDI (FEDI™) was chosen due to its design advantages that include reduced hardness scaling.

This water treatment system is key to long-term success of the terminal’s liquefaction process. Our FEDI™ successfully delivered a reliable EDI solution, coupled with a modular design, that allows for easy expansion for future growth as the plant plans to expand its capacity.
