Toray Membrane

Toray membrane element is a reverse osmosis product which is widely used in seawater desalination, ultrapure water production, wastewater recycling. It has been applied in large/medium/small water treatment systems. It is a high flow product that saves both the operation and installation cost, and with low pressure, high salt removal performance.
It is recognized worldwide as having excellent stain resistance, brine, ultrapure water and desalination products.
