Desalination Plants

Our desalination water treatment systems feature both membrane-based and thermal desalination technologies. Our designs are state-of-the-art, optimizing efficiency, reliability, product water quality, and overall low cost per unit of water.

They recover higher percentages of the feed water as good quality product water. Boiler feed quality may be obtained by using specialized equipment designed for that purpose, even from seawater feed TDS containing up to 50,000 ppm.

Landmark manufactures a full line of desalination water systems designed for heavy or continuous duty service in the marine applications where quality and dependable performance is a key.

In addition to full-scale plants developed under Engineering, Procurement and Construction (EPC) and BOOT contracts, we offer customized, pre-engineered containerized solutions that provide a compact footprint and reduced installation time.
