REVERSE OSMOSIS & NANOFILTRATION
We are the recognized world leader in producing elements to demineralize brackish water, desalinate seawater and more.
Reverse Osmosis & Nanofiltration
Compared to other filtration technologies that rely on a screen or filter to remove particles, reverse osmosis (RO) and nanofiltration (NF) are pressure-driven separation processes that employs a semi-permeable membrane and the principles of cross-flow filtration.
We provide the most widely used RO and NF technologies in the world—trusted by municipalities, manufacturers of all types, small businesses and families wanting clean, healthy water at home.
REVERSE OSMOSIS AND NANOFILTRATION TYPES
Driving technology forward is what we do best. With decades of global experience in working with the most difficult problems in purifying water or liquid streams, regional technical support, and industry-leading innovations, our RO and NF technologies bring world-trusted, top-tier technology to your water filtration needs.
