UF Membrane Module 9 nti PVDF Ultrafiltration Membrane Module UFF2880 Hloov Project
Daim ntawv thov
Kev kho cov dej kais dej, dej saum npoo av, dej zoo thiab dej ntws.
Pretreatment ntawm RO.
Kev kho, rov siv dua thiab rov siv dua cov dej khib nyiab hauv kev lag luam.
Filtration Performance
Cov khoom no tau raug pov thawj tias muaj cov teebmeem hauv qab lim dej raws li kev pabcuam ntawm cov dej sib txawv:
| Cov khoom xyaw | nyhuv |
| SS, Particles> 1μm | Kev tshem tawm tus nqi ≥ 99% |
| SDI | ≤ 3 |
| Kab mob, kab mob | > 4 log |
| Tawg | |
| TOC | Kev tshem tawm tus nqi: 0-25% |
* Cov ntaub ntawv saum toj no tau txais nyob rau hauv cov xwm txheej uas pub dej turbidity yog
