“Dr. Elimelech’s pioneering research has not only enriched the academic community’s understanding of a highly complex topic, but also led to innovative approaches to addressing critical environmental issues and spawned the growth of an industry,” he said. “ARKA’s unparalleled technology expertise is contributing to the success of our nation in a variety of sectors and creating high-skilled jobs that will attract investment to our state and enhance our economy,” Lamont added.

Elimelech’s research and development is in the application of membrane processes including forward osmosis or FO (for desalination and water reuse), high-pressure reverse osmosis or HPRO (for brine concentration and management), and low-salt-rejection reverse osmosis or LSRRO (for brine management and minimal- and zero-liquid discharge applications).

HPRO and LSRRO are expected to revolutionize low-energy, low-cost brine management. Gradiant, a US company specializing in brine management (minimum- and zero-liquid discharge, MLD/ZLD), is commercializing a variant of the LSRRO and FO technologies, which is called Counter Flow RO (CFRO). The current market of brine management is estimated at $11.5B.

Elimelech’s innovative work on forward osmosis (FO) profoundly impacted the desalination and water industry. He was a co-founder of Oasys Water, a company which commercialized the ammonia-carbon dioxide FO desalination technology. More than 13 new FO start-up companies have been formed following his pioneering FO research.

In a recent breakthrough, Elimelech showed that the solution-diffusion model, which has been used to describe water transport in reverse osmosis (RO) membranes for more than 50 years, is fundamentally flawed and he proposed an alternative mechanism and theory for water transport consistent with experimental observations. This finding has direct implications for the design of high-performance desalination membranes.

In 2021, Elimelech was appointed Sterling Professor of Chemical and Environmental Engineering, the university’s highest academic rank; the first engineering professor at Yale to earn this distinction.

ARKA is a world leader in the design, development, manufacture, integration and test of precision optics, telescopes and electro-optical payload systems for defense, aerospace and scientific applications. ARKA’s mission has grown to include groundbreaking communications, software development, and data processing capabilities, expanding their reach to new areas of innovation.
