Comparison between polyethersulfone membrane and cellulose acetate
There are polyethersulfone membrane (PES Membrane) and cellulose acetate (Cellulose Acetate), both of which have their own characteristics in many aspects.

Polyethersulfone membrane, the material is tough, its structure is dense and regular. In the field of filtration, it has good interception effect on impurities such as particles and bacteria, can operate stably under high pressure, and resists a certain degree of chemical corrosion, so it is suitable for liquid filtration in complex chemical environments. For example, in industrial wastewater treatment, it can effectively intercept heavy metal ions and organic pollutants to ensure the quality of the effluent.

Cellulose acetate has good hydrophilicity, smooth water molecules pass through, and low energy consumption. Its membrane formation process is relatively simple and the cost is controllable. It has outstanding performance in water purification. For example, when preparing drinking water, it can efficiently remove bacteria, viruses and other microorganisms in water without affecting the taste and quality of water.

However, although polyether sulfone membrane has excellent performance, high cost, and inferior hydrophilicity to cellulose acetate, it is slightly insufficient in some scenarios that require extremely high water flux. Although cellulose acetate has good hydrophilicity and low cost, its mechanical strength is limited. Under high pressure and high shear force environments, the stability of the membrane may be affected.

To sum up, the two have their own strengths. When applying, it is necessary to weigh the choice according to specific needs and environmental conditions to achieve the best use effect.
