Abstract： |
| Membrane flux of the original molded sand plate module was quite small, less than 7 L/(m2•h), when it served as the support of self-forming dynamic membrane. To improve the membrane flux, surface modification was conducted by coating the molded sand plate module with organic membrane materials. The optimized parameters included sand sizes, the composition and the concentration of organic membrane solution. The optimal values were 50-100 mesh numbers for the sand materials, and the original concentration of PVDF for the organic membrane solution, respectively. Finally, a novel type of sand plate membrane module was developed after its surface modification. A test of a submerged MBR for pilot-scale study at 16 L/(m2•h) with this type of membrane modules was conducted, and the system performed stably. For wastewater treatment, the sand plate membrane module will be a promising material used in MBR given its high strength and long life-span. |
