Fouling resistance technology designed for challenging feed
Excellent rejection delivering high quality permeate
Enhanced durability with wide pH tolerance range
The Product
The CLEAR Classic FR reverse osmosis elements are brackish water membranes with enhanced fouling resistance properties which offer a combination of high rejection and high product durability to treat challenging feed waters. The CLEAR Classic FR products are suitable for applications where stringent permeate quality requirements need to be met, such as in municipal water treatment, industrial demineralization, and wastewater recycling.
The Series
The Aquaporin Inside® CLEAR series features the world’s first and only biomimetic brackish water reverse osmosis products in the market. The Aquaporin Inside® technology replicates nature’s way of filtering water by incorporating the aquaporin water channels into membranes, which enables fast, energy-efficient and natural water filtration.
