The membranes have good durability (>12 months) and a short response time (<5 s).
The membranes have good durability ( > 9 months) and a short response time (ca.
We have demonstrated that the membranes are stable for over 6 weeks continuous operation at room temperature.
The results show that the membranes are stable upon exposure to 30 wt % MEA for at least 4.5 months.
The membranes also display an excellent oxidative stability, which suggests a good lifetime usage of the membranes.
Additionally, the obtained membranes also possess great potential for long-time operation, as demonstrated by stability test.
The present membranes have much potential for use in long-term water treatment with high efficiency and stability.
Compared to most commercially available membranes they have superior long-term stability and very relevant performance.
Long-term stability of the grafted membranes is much better than the pristine PBI membranes.
The results showed that these membranes are efficient for treatment of petroleum refinery wa...
