The traditional process of membrane separation is compared with the effect of membrane separation.

Membrane separation should have a larger film area per unit volume, the membrane cutting speed is fast, in order to reduce the polarization of thick difference, the film cleaning and replacement is convenient, low cost, high retention rate characteristics.
the traditional process of membrane separation and membrane separation process effect: 1, high filtration accuracy, good de-miscellaneous effect, can achieve molecular-level filtration separation, effective interception of large molecular impurities.
2, quality, high purity, high price, stable quality, competitiveness significantly improved.
3, the whole membrane separation process of the effective substance only a small part will be intercepted or through, the amount of loss is relatively small, the total yield increased.
4, high degree of automation of equipment, simple operation, low labor costs, cost is greatly reduced.
film separation characteristics: 1, at normal temperature and low pressure separation and concentration, so low energy consumption, so that the operating costs of equipment is low.
2, small size of equipment, simple structure, so low investment costs.
3, membrane separation process is simply pressurized delivery of liquid, the process is simple, easy to operate and manage.
4, membrane as a filter medium is a uniform continuum made of polymer material, pure physical method filtration, material in the separation process does not occur qualitative changes (i.e. does not affect the molecular structure of the material).
film separation type: 1, tube device.
with a titular membrane and supported by a porous tube, forming a device similar to a tube shell heat exchanger, divided into internal and external pressure type, each with a porous tube supported on the outside or inside of the membrane.
-pressing membrane surface for microfiltration and over-filtering.
2, plate frame device.
is inserted between the same-sized film groups, intersetrilly inserting the partitions to form the flow path of the two fluid streams.
the membrane group can be placed in a uniform electric field, this structure is suitable for electrodialysis.
plate frame device can also be applied to the membrane on both sides of the fluid static pressure difference is smaller than filtering and permeation.
3, hollow fiber type device.
hollow fiber does not need support and can withstand a high pressure difference, in a variety of membrane separation equipment, its unit device volume content na film area is large.
a device similar to a tube shell heat exchanger with hollow fibers.
hollow fiber diameter of about 0, 1 to 1mm, side by side up to millions of roots, fiber end is sealed with epoxy resin, forming a tube plate, encapsulated in a pressure vessel.
hollow fiber type is suitable for reverse osmosis and gas osmosis separation.
Letrade according to the processing requirements of the equipment to customize cost-effective process package, the entire equipment for a comprehensive analysis and reasonable design, so that the design of equipment, manufacturing, production, monitoring of the process links to be effectively controlled, in order to achieve the economic performance of the entire process package and technical advantages of the dual combination, so as to provide customers with both professional and perfect fluid separation purification process package design.
