What Is a Millipore Filter?

Microporus filters are collectively referred to as membrane filters with a pore size of 0.2-1um. Referred to as MF.

Microporous filter

Micropore

Micropore filter is a new type of filtering equipment developed at home and abroad. It can filter out particles and bacteria over 0.1um of liquid and gas. It has the advantages of high filtration precision, fast transition speed, less adsorption, no medium shedding, resistance to acid and alkali corrosion, convenient operation and so on. Now widely used in medicine, chemical industry, electronics, beverages, fruit wine, biochemical water treatment, environmental protection and other necessary equipment in the industry.

Filtration capacity T / H: 0.05-20

Filter use pressure mpa: 0.1-0.6

Filter specifications: 1,3,5,7,9,11,13,15

Filter use temperature ° C: 5-55

Filtration accuracy (um): 0.1, 0.2, 0.45, 1-60

Filtration capacity (t / h): 0.5-100

Filter element length (m / m): 250-1000

Working pressure (Mpa): 0.1-0.6

The filter cartridge has 1 core, 3 cores, 5 cores, 7 cores, 9 cores, 11 cores, 13 cores, 15 cores, 21 cores, and 32 cores.

Foldable filter element length is 10, 20, 30, 40

Filter element materials are polypropylene, polytetrafluoroethylene, acetate fiber, polyethersulfone folding filter element, etc.

Filter pore size: 0.1um, 0.22um, 0.45um, 1um, 3um, 5um, 10um, etc.

1. Thoroughly clean the filter and filter connection parts, and properly install the filter element and housing.

2. Before starting, check whether the booster pump runs smoothly, check whether the connection is tight, and whether the valves are closed.

3. Before starting, slowly open the inlet valve, exhaust it, and then open the outlet valve for normal filtering.

4. If it is found that the filtration pressure difference is greater than 0.1Mpa or the flow rate is significantly reduced, it indicates that most of the pore diameter of the filter element has been blocked. It is recommended that customers clean or replace the filter element.

The stainless steel microporous filter is composed of a folding microporous membrane filter element and a stainless steel outer cylinder, which is equipped with a single-core or multi-core filter element. The filter cylinder body is connected by a quick-release clamp or a quick-opening ring bolt. Convenience. The inner surface of the filter is mirror polished (roughness Ra0.28m), no hygienic dead angle, and meets the requirements of the "FDA" and "GMP" specifications

The microporous filter is divided into chemical grade and food grade. Food grade must be manufactured according to FDA standards. The filter material is high-quality stainless steel (304 / 316L), both inside and outside are finely polished without dead ends. Its characteristics are small size, light weight, easy to use, large filtration area, low clogging rate, fast filtration speed, no pollution, good thermal stability and chemical stability.

This series of stainless steel microporous filters can remove most of the particles, so they are widely used in fine filtration and sterilization processes.

The filter cartridge has 1 core, 3 cores, 5 cores, 7 cores, 9 cores, 11 cores, 13 cores, and 15 cores.

Folding

Micro-pore filter element: Polypropylene membrane (PP) element, Teflon

Microporous filters are now widely used in pharmaceuticals, chemicals, electronics, beverages, fruit wine, biochemical water treatment, environmental protection and other necessary equipment in the industry. Therefore, its maintenance is very necessary, not only can improve the filtration accuracy, but also can extend the life of the microporous filter. What can we do to maintain the microporous filter?

There are two types of microporous filters for maintenance, namely precision microporous filters and coarse filters.

1.Precision microporous filters

The core of the precision microporous filter is the filter element. The filter element is composed of special materials, which are suitable for damage and need special protection.

When the precision microporous filter works for a period of time, the filter element traps a certain amount of impurities. At this time, the pressure drop increases and the flow rate will decrease. It is necessary to remove impurities in the filter in time and clean the filter element.

When removing impurities, pay special attention to the precision filter element, which must not be deformed or damaged, otherwise, the filter element can be installed again, and the purity of the medium after filtering cannot meet the design requirements.

Some precision filter elements cannot be used repeatedly, such as bag filter elements, polypropylene filter elements, etc.

If the filter element is found to be deformed or damaged, it needs to be replaced immediately.

2.Microfiltration filter for coarse filtration

The core of the coarse-filtration microporous filter is the filter core. The filter core is composed of a filter frame and a stainless steel wire mesh. The stainless steel wire mesh is a suitable piece of damage and requires special protection.

After the filter has been working for a period of time, certain impurities have precipitated in the filter core. At this time, the pressure drop increases and the flow rate will decrease. It is necessary to remove the impurities in the filter core in time.

When cleaning impurities, pay special attention to the stainless steel wire mesh on the filter element can not be deformed or damaged, otherwise, the filter is installed, the purity of the filtered medium can not meet the design requirements, and compressors, pumps, meters and other equipment will To destruction.

If the stainless steel wire mesh is found to be deformed or damaged, it needs to be replaced immediately.

Microporous filters have high filtration accuracy, fast transition speed, less adsorption, no medium shedding, resistance to acid and alkali corrosion, easy operation, and a wide range of applications, and its role is becoming more and more important.
