Membrane Filter Cartridge

What is The Membrane Filter Cartridge?

Membrane filter cartridge means that the material of the membrane water filter cartridge uses PES membrane water filter, PTFE membrane water filter; PVDF membrane water filter, PBT membrane water filter, and PFA membrane water filter.

Used in high-purity water production, electronics industry, pharmaceutical industry, food and beverage industry, membrane in water purifier or to filter some acid, alkali and other strong corrosive liquids.

Commonly use filtration rating 0.1μm, 0.22μm, 0.45μm, 1μm.Length: 10”, 20”, 30”, and 40”.With various connection adaptors meet different requirements. The graded pore size distribution from coarse (upstream) to fine (downstream) removes particles gradually and extends the filter’s service life.

Membrane water filter has high dirt holding capacity and good particle interception efficiency to protect the terminal sterilization filter. The membrane water filter has high filtration accuracy.

The production conditions must be produced in a clean workshop with high cleanliness, membrane filtration equipment membrane filtration system so as to ensure that the water filter itself is clean and will not introduce new impurities and precipitation during use.

The water filter that meets membrane housing condition is safe and reliable. , Intercept foreign particles, membrane filter for ro system colloids, membrane filtration unit bacteria in the purifying water ro filter systems.

In order to ensure that the membrane water filter is qualified, membrane filter housing each membrane water filter must undergo an integrity inspection test before leaving the factory to meet your requirements.

Water filter must 100% integrity test before delivery to ensure integrity and sterilization.

Classification of Membrane Filter Cartridge

According to the material of the filter membrane, it can be divided into:

• PES membrane filter cartridge
• PTFE membrane filter cartridge
• PVDF membrane filter cartridge
• Nylon membrane filter cartridge
• PFA membrane filter cartridge

According to different working conditions, choose membrane water filters of different materials.

Therefore, according to the different water filter RO working conditions, we are divided into:

• Electronic grade precision membrane water filters,
• Medical grade precision membrane water filters,
• Food & Beverage grade precision membrane filters cartridges.

The structure of Membrane Filter Cartridge

The structure of the water filter consists of frame, end cap, filter membrane, sealing ring, etc.

Because polypropylene itself is an organic compound, it can withstand the corrosion of general concentrations of acid and alkali, but for special acid, alkali and organic compounds, membrane cartridge filters based on similar compatibility principles.

We do not recommend the use of polypropylene, so the outer frame and sealing ring of the membrane water filter cannot use polypropylene

Why do you need Membrane Filter Cartridge?

For special water filter ro working occasions, because the water filter ro purity requirements are relatively high, and the water source is usually sea water, surface water or tap water, large water filtration system these raw water contains a large number of impurity particles, which are far from meeting the requirements.

So industrial water filtration a set of membrane filtration water treatment is required Filtration purifying water ro filter systems, after filtering to obtain pure water, to ensure your normal use.

Polyethersulfone has good chemical properties, micro membrane filter manufacturing company good heat resistance.

Filter for water system no corrosion by acid and alkali at high temperatures, industrial water filter manufacturers good creep resistance, low linear expansion coefficient, and low-temperature reliability.

Filter for water system Non-toxic, but its resistance to polar solvents such as industrial water filter cartridge acetone and chloroform is industrial membrane not good.

The PTFE filter cartridge has the following characteristics:

1). Material: PTFE water purifier cartridge is PTFE membrane with excellent performance, wide chemical applicability, biological safety and pyrogenic control unique hydrophobicity and hydrophilic.

2).

When used for gas filtration, it can intercept 100% of various phages, bacteria and particles above 0.02um.

3). Hydrophilic: Used for liquid filtration to achieve sterility, wide chemical applicability, high quality water filtration system strong acid and alkali resistance, and high ozone strength.

How the Membrane Filter Cartridge works？

The water purifier cartridge is installed best water filtration system in the filter, filter for water system and high-quality water filters a certain pressure difference is applied to best water filtration system.

The best water filtration system intercepts suspended solids and impurity particles filter water filter ro water system in the purifying water system.

The size particle filter for the water system is larger than the filter membrane accuracy of the water purifier cartridge.

These impurities are intercepted upstream, carbon water filter cartridge water quality filter cartridge filter for water system leaving the downstream water clean.

2) Material Construction and Technical Parameters

Advantages of progressive pore size membrane:

The upstream and downstream of the pre water filter cartridge is a support layer, which plays a supporting role on the one hand.

As a diversion layer, the non-woven fabric not only plays a role of diversion, but also can intercept some impurities, from the support layer to the non-woven fabric to High-precision pre water filter material.

The pore size of the pre water filter material decreases successively and intercepts in layers. This is the advantage of the pleated pre water cartridge filter, which can achieve high precision.

You can see that the water pre water filter material is from the inside to the outside, the pore size is from large water filtrations systems too small to large.

The inner membrane is a superfine fiber imported from Japan. The outermost layer is a rhombus mesh, pure filter replacement which acts as a supporting layer. At the same time, a polypropylene filter is a non-woven fabric for diversion.

The inner layer is high. Precision pre water filter membrane, filtering material the pre water filter membrane has a high porosity,

The porosity of the pre water filter cartridge can be understood as follows: if there is only cartridge water filter one hole on water filtrations systems pre-water filter membrane filter housing.

Its porosity is extremely low, filter replacement and the corresponding flow rate is also extremely small.

On the contrary, if there are many small holes on the pre water filter membrane. The size of the holes is uniform and all are of specific size. Its flow rate will be larger than the former.

Our filter membrane filter housing is based on the above characteristics. Therefore, there is a positive effect on the distribution of flow and the size of flow.

Because the filter membrane is a gradual pore size, filter housing its industrial water filtration system water filtration mechanism belongs to deep filtration, water filtrations systems and it has high dirt holding capacity and a high flow rate.

The difference between filter housing micro-filtration membranes, ultra filtration system filter housing ultrafiltration membrane and reverse osmosis membrane.

Their pore size is different from the material of the membrane, so the removed impurity particles, water filtrations systems microfiltration and ultrafiltration are all membrane separation technologies driven by pressure.

Membrane for reverse osmosis is cartridge filter a membrane separation operation in which the pressure difference is used as the driving force to separate solvent from the solution.

Microfiltration is also called micro-porous filtration. It is a kind of precision filtration, which intercepts particles such as gravel, sediment filter cartridge silt, water filtrations systems clay and giardia.

Sediment filter cartridge ultra-filtration system crypto sporangium, algae and some bacteria in the solution, water filtrations systems and a large number of solvents, small molecules and a few large molecules Solutes can penetrate the separation process of the membrane.
