  • 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.

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.
