The Applications Of Membrane Filter

Membrane Filter Water Treatment

Membrane filter water treatment is a solid-liquid separation technology. It filters water through membrane holes and retains impurities in water without chemical changes. However, due to the very small size of the membrane holes, there are some corresponding technical problems. Hawach membrane filter is also used to treat raw water in the feed water, but it is different from filtration membrane separation technology. Hawach has Hydrophilic PTFE Membrane Filters, Microporous Glass Fiber Membrane Filters, Cellulose Acetate Membrane Filters for you to choose from.

Membrane Filtration Method

Membrane filtration method is a method of measuring the radioactivity in antigen-antibody complexes by using the characteristic of microporous membranes to better adsorb proteins and allowing small molecule antigens to filter through. The membrane is a solid phase method. Used to separate immune complexes from free antibodies or antigens.

Membrane filtration is the popular method which is used for separating particles in liquid solutions and gas mixtures. Acting as a barrier which can retain larger particles, and allow smaller molecules to pass through the membrane as while, membrane filter can separate substances when a driving force is applied across the membrane.

Under gravity, molecules always move from areas of high concentration to low concentration naturally. But if we apply external pressure, molecules can flow oppositely, from areas of low concentration to high one. Due to the pressure difference on both sides of the membrane, the permeate can go cross the membrane steadily, which allows the final product come out in the higher overall yields.

We can find four methods of membrane filtration in the labs, they are microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. With the membrane filtration, we can reduce the energy usage and lower the operating cost as while. You will find that fewer chemical additives are needed to remove impurities too.

Due to the advancements of the membrane filter, the processes of the membrane filtration are widely used in the field of removing bacteria, microorganisms, particulates, and natural organic material by separating color, tastes, and odors from water and gas.

Applications of membrane filtration

What are the applications of membrane filters? In addition to water treatment, membrane filtration applications for ultra-pure water production and desalination. Generally, reverse osmosis membranes (nanofiltration membranes) are used. Application of membrane filtration. Ultrafiltration membranes and microfiltration membranes are commonly used in feces and urine treatment, urban sewage treatment, and various wastewater treatments.

In industry, it can be used in dairy products manufacturing, semiconductor manufacturing, food manufacturing, paper manufacturing, and pharmaceutical manufacturing. Ultrafiltration membranes and microfiltration membranes are also commonly used.

In addition, membrane filter is also used in food and beverage, medical pharmaceuticals, municipal industrial water treatment, industrial high-purity water, boiler water supplement, seawater desalination, ultra-pure water in electronic industry, wastewater treatment and reuse, material concentration and purification, and other industries.
