1.specialized membranes for ultrapure water
By adopting the core patent of CSM, specialized membranes for ultrapure water can resist washing with acid and alkaline and high pollution. All the produced water’s TOC can be below 20PPB, and can be widely applied in electronic ultrapure systems.
Advantages
→high TOC removal rate
→anti-pollution performance has been added
→low TOC dissolved rate, short TOC standard washing period
→ultrapure water system applied in electronic chips industry, with higher stability than before
Components Category | Type | Water output [gpd(m3/d)] | Removal (%) NaCl IPA | | Test condition |
Normal RO membrane | RE8040-UE | 9, 000(34.1) | 99.5 95.0 | 225psig | NaCl 2, 000ppm IPA 1, 000ppm Temp. 25℃ Recovery 15% |
Efficient anti-pollution Ultrapure water membrane | RE8040-HLE | 9, 000(34.1) | 99.5 96.0 |
Ultrapure water membrane for low pressure | RE8040-UL | 10, 000(37.9) | 99.0 92.0 | 150psig |
Notes: 1. The statistics above was tested and recorded after testing for 30 minutes under normal conditions.
2. In order to shorten the washing period, all the produced membranes have been carefully washed before being sent to the clients.
