Daltonen Focusing on Separating Membrane Products and Fluid Technology Services.
DA-SW400-HR
Product Introduction
The Daltonen Membrane SW seawater desalination dedicated reverse osmosis membrane element adopts innovative membrane technology, with strong compressive tightness of the membrane support layer, thick and dense skin layer, wear resistance, and chemical degradation resistance; By utilizing a short membrane structure and increasing the number of membrane pages, the membrane efficiency is greatly improved, achieving high desalination rate and boron retention rate under high water production conditions. Wide pH resistance range, high cleaning efficiency, and the ability to perform powerful and efficient cleaning with ordinary acids and alkalis. Due to thorough cleaning, the membrane system can operate at low pressure for a long time, greatly reducing operating costs and improving the economic benefits of the entire system
Product advantages
· High desalination rate
· Has compressive tightness, pollution resistance, and high cleaning efficiency
· Improving the overall economic benefits of seawater desalination systems
