Membrane Filter Principle Membrane filters are thin layers of semi-permeable materials that separate chemicals when they are subjected to a driving force. The membrane works by separating substances physically. Biological filters
Nanofiltration, referred to as NF, this type of membrane pore size is between ultrafiltration and reverse osmosis, can filter water, solvents, monovalent salts, etc. , sugar and dyes etc. Filter particles with specifications less than 0.
2020年4月9日 · 6. Let the cleaning solution soak the membrane filaments in the membrane tank for 2 ~ 4 hours, while soaking, it can be aerated to enhance the cleaning effect. 7. First perform alkaline washing, then acid washing, and finally, wash with oxidant solution. 8.
If the membrane does not have a substrate, it is bio-directional and either side can be used as the inlet. If it has a substrate, the substrate layer will be more coarse and ridged than the membrane side. The membrane side would be the inlet and the coarse substrate side the
