Hollow fiber membrane manufacturer quotationworking principle

The working principle of hollow fiber membranes is based on molecular diffusion and pressure drive. The mixture enters from the outside of the membrane by applying pressure, and then enters the inner pores through molecular diffusion. Inside the inner pore, the molecules of the substance can be further transferred or intercepted through the pores of the shell layer based on their molecular size and solubility properties, achieving the separation of the substance. In addition, hollow fiber membranes can also utilize solvents to gradually flow out of the membrane pores to increase solute concentration in the core.

Hollow fiber membrane manufacturer quotationApplied to the treatment of production and domestic wastewater in pharmaceuticals, brewing, catering, chemical industry, municipal wastewater reuse, hospitals, residential wastewater reuse, papermaking, and other industries. Membrane separation technology is a widely used separation technique for separating, concentrating, and purifying solution or gas substances. The membrane wall is densely packed with micropores, and the original solution passes through one side of the membrane under a certain pressure. The solvent and small molecule solute permeate through the membrane wall as the filtrate, while the large molecule solute is intercepted by the membrane, achieving the purpose of material separation and concentration. The membrane separation process is a dynamic filtration process, in which large molecular solutes are blocked by the membrane wall and flow out with the concentrated solution. The membrane is not easily clogged and can be used continuously for a long time. The filtration process can operate at room temperature and low pressure, with no phase change and high efficiency and energy saving. Hollow fiber membrane is an important form of separation membrane, and membrane products include hollow fiber microfiltration membrane (MF), hollow fiber ultrafiltration membrane (UF), hollow fiber reverse osmosis membrane (RO), hollow fiber curtain membrane (FPM), etc., as well as the application of MBR technology. It is mainly used in mineral water purification, production and domestic water purification, pharmaceutical purification, juice concentration, papermaking electroplating chemical industry and other pollution industries such as water treatment and recovery, urban sewage reuse and other pharmaceutical, chemical, construction, textile, papermaking, petrochemical and other industries.

Precautions for use:

1. Storage of membrane components: During transportation and storage, the membrane components should be kept in a dry, cool, and ventilated environment, avoiding direct sunlight and high temperatures.

2. Safe operation: During installation and use, appropriate protective equipment such as rubber gloves, protective goggles, etc. should be worn to prevent accidental injury.

3. Cleaning and maintenance: Regularly clean and maintain the hollow fiber membrane to maintain its good separation performance and extend its service life. When cleaning, appropriate cleaning methods and cleaning agents should be selected based on the membrane material and contamination situation.

4. Pressure control: During operation, the operating pressure should be strictly controlled to avoid exceeding the bearing range of the membrane component, which may cause membrane damage or performance degradation.

5. Chemical compatibility: Pay attention to the chemical compatibility between the hollow fiber membrane and the liquid being processed, and avoid using chemicals that are incompatible with the membrane material for cleaning or processing.

6. Regular testing: Regularly test and evaluate the performance of hollow fiber membranes to promptly identify and solve problems.
