Water Solutions Dry Seawater Reverse Osmosis Elements
DuPont Water Solutions has a long history of proven science and innovation. Reverse osmosis (RO) technology has come a long way over the last 40 years – desalination today costs only half of what it did 10 to 15 years ago. Water Solutions has focused its research and expertise in membrane development and design to meet the growing market need for seawater and brackish membranes that offer high permeability, high salt rejection and antifouling. Now, our ever-evolving R&D pipeline has led to the development of the industry’s first dry-test seawater reverse osmosis (SWRO) membrane.
Transition to dry SWRO portfolio
The new dry SWRO product portfolio is a breakthrough for the water treatment industry. Continuous advances in membrane chemistry, testing methods and procedures, together with automated precision single source manufacturing, enables DuPont to be the only supplier to offer dry SWRO elements.
Why dry?
Dry SWRO elements offer customers significant advantages versus wet elements. Wet elements contain a preservation solution that needs to be checked after one
year of storage, which may require eventual replacement. Not only does this add to the overall cost of the membrane, but it involves a high level of manpower, as well as reduces the possibilities of long-term storage and warehouse planning.
