Effective Membrane Area
Appearance and Characteristics
The pore diameter of U-Flow Hollow Fiber Membrane are gradually increasing from outer layer to internal layer , and become asymmetric structure which is in favor of dcreasing filter drag.
U-Flow Hollow Fiber Membrane possesses alkalinity-resistant and acidity-resistant abilities and high performance makes it outstand from other competitors.
Feature Comparison Of External and Intemal Pressure Type Membrane.
External Pressure Type U-Flow Hollow Fiber Membrane is superior regular intenal Pressure Type.
Water Consumption of Cleaning
Consumption of Operating Energy
Pore Size and Distribution
The pore size of External Pressure Type U-Flow PES Hollow Fiber Membrane is small,and the rejection effect is great.
U-Flow PES is superior to PVDF Hollow Fiber Chemical-tolerant area.
U-Flow Module Technology
U-Flow series of Membrane uses progressive technology and unique design to lower producing cost and to develop those membranes which can be operated under pressure 0.5kg f/cm2
