Description
- 高抗污染通量
采用专利亲水改性技术，具有优异的抗污染能力，在较低的跨膜压差下仍能保持较高的运行通量，并且在使用过程中通量下降的时间较长。 - 卓越的水质
0.03μm高精度过滤孔径，配合均质海绵结构，对水中胶体颗粒、细菌、病毒等去除率高，确保产水水质始终优良。 - 使用寿命长
膜纤维密封采用离心密封工艺，密封层无气泡，根部无蠕变，可承受反复高强度气水冲刷，最大限度降低纤维断裂风险，延长使用寿命。 - 产水效率高：
膜纤维采用高规格PVDF材质，力学性能优异，断裂强力≥4.5N，伸长率≥150%。应用工艺可实现气水联合反冲洗，清洗彻底，有效控制污染，同时减少反冲洗用水量，提高产水效率，回收率可达95%以上。 - 通用结构，更换无忧
水益加压式超滤膜产品可无缝替换市面上主流的超滤膜产品，安装简单，改造成本低，运行维护便捷无忧。
