THE QUEST to optimize water re-use and anticipate regulatory pressures is driving many plants to give increasing attention to their wastewater. To help meet the challenges, wastewater treatment specialists such as Dow Water Process Solutions and Microdyn-Nadir are introducing new technologies. Meanwhile, researchers at universities in Germany, Spain and Singapore are working on potential future options, scaling up separation techniques based on ionic solutions and biomimetic membranes. "As part of Dow's reduce, reuse and reclaim circular economy approach we are really focused on the finite water supply. So we want to squeeze as much as possible from all the water used by industry, including the chemical industry," says George Barclay, global RD director at Dow Water Process Solutions, Edina, Minn.
