Fig. 2From: Effect of hollow fiber diameter and membrane surface area of polymethyl methacrylate membrane on filter lifetimeTMP A and pressure drop B when the pressure was stable in all the experiments. The TMP was significantly lower for the CH-1.8W filter than for the CH-1.0W and CH-1.0N filters. The pressure drop was significantly lower for the CH-1.8W filter than for the CH-1.0W and CH-1.0N filters, and that for the CH-1.0W filter was lower than that for the CH-1.0N filterBack to article page
