Membrane Technology

The relationship between microporous filtration membrane flux and pressure is described by the concept of transmembrane pressure (TMP).

Water is the source of life, and its role in modern industrial production is irreplaceable. As far as the semiconductor and microelectronics industries are concerned, water is used in some major proce

0.22 micron filter membranes are usually used in laboratories and the medical industry. They are mainly used to remove very small particles in solutions, such as bacteria.

The filtration of organic solvents is inseparable from microporous filtration membranes. So, what kind of membrane is suitable to choose?

Filter paper and microporous filter membrane are both particle filtration media and are commonly used in filtration applications in various industries. However, they are different in terms

Prefiltration of microporous filtration membranes refers to the process of removing some larger particles or contaminants before the feed solution enters the formal microporous filtration membrane.

When selecting microporous filtration membranes, the terms "rated pore size" and "absolute pore size" are often used. So, what are their general meanings and differences?

Microporous filtration membranes can be used to remove bacteria from solutions. The working principle is very simple. The pore size of the membrane is smaller than the size of the bacteria, prevent...

The use of microporous filtration membranes will become contaminated by particles, colloids, organic compounds and microbial growth over time. The fouling of pollutants will reduce the performance of

What is conductivity? Conductivity is a measure of the material's ability to conduct current. It is the reciprocal of resistivity.

The pore size of a microporous filtration membrane is a key parameter that determines its separation performance. Most methods for evaluating pore size use a variety of measurement methods.

The performance of microfiltration membranes is affected by many variables, here is a brief summary:
1. Membrane pore size. The size of the membrane pore size is a key variable that

The working principle of ion exchange membranes (IEMs) is based on their unique molecular structure, which allows the selective transmission of certain ions while excluding others.

An electrolyte membrane, also known as an ion exchange membrane, is a semipermeable membrane that conducts certain ions while blocking other ions or substances of different charge, such as an electrol

Endotoxin is a heat-stable toxic substance that can usually withstand commonly used sterilization temperatures, such as dry heat or autoclaving, and can withstand temperatures up to 250°C for a short

Modified positively charged filter membrane refers to a filter membrane with a positive charge after chemical modification. The introduction of positive charges on the membrane surface can

The ASTM F83 test mentioned here should be ASTM F83-15a related to the filter membrane. ASTM F838-15a is a standard test

The double-layer gradient structure of microporous membranes refers to two layers of membranes with different pore sizes, usually arranged such that the layer with larger pore size

What is the "fiber-free release" standard of microporous filtration membrane? It refers to the phenomenon of fiber shedding on the surface of the membrane caused by factors such as material, productio

Medical sterile filtration is usually performed using filter membranes made of polyethersulfone (PES), polyvinylidene fluoride (PVDF) or nylon. A prominent factor in the selection of these membrane ma
