Microfiltration of the products you picked the right?

There are three kinds of microfiltration filtering principle: screening and filter filter, deep. Generally think that the separation mechanism of microfiltration for screening machine, decide the physical structure of the membrane. In addition, factors such as adsorption and electric properties of withholding rate may also be affected. The effective separation range 0. 1 - 10 microns particles, static pressure difference operation is 0. 01 - 0. 2MPa。

particles in the process of microfiltration intercept location, can be divided into three intercept mechanisms: screening, adsorption and bridging, they microfiltration principle is as follows:

( 1) Screening: microporous membrane filter interceptor with membrane pore size is larger than the membrane pore size or particles, also known as mechanical entrapment.

( 2) Adsorption: particles onto the membrane by physical and chemical adsorption. Particle size is less than the film hole can be trapped.

( 3) Bridge: particle accumulation jostled each other, resulting in many particles can't enter the film hole or card in the hole, to complete the intercept.

the main equipment is microfiltration membrane, microfiltration membrane, internal and external diversion layer, filter plate, shell and center pole and can form filter ( Filter has folded filter, line winding filter, melt-blown filter, etc. ) 。 In industrial applications, the microfiltration equipment and some of the organic combination of the auxiliary equipment of form a complete set, namely the assembled into an independent micro filter system, such as continuous micro filtration system. Determine the membrane separation effect is the physical structure of membrane, pore shape and size. According to the microfiltration membrane material divided into two categories: organic and inorganic, organic polymer with cellulose acetate, polypropylene, polycarbonate, polysulfone, polyamide, etc. Inorganic membrane materials with ceramic and metal, sintered metal ( Such as stainless steel) , alumina, glass, silica, etc.

applications:

( 1) The water treatment industry, suspended solids in water, removal of tiny particles and bacteria;

( 2) Electronic industry, semiconductor industry ultrapure water, cleaning water terminal treatment of integrated circuits;

( 3) The pharmaceutical industry, medical pure water in addition to bacteria, in addition to pyrogen, anti-bacterial drugs;

( 4) The health care industry: removal of tissue fluid, antibiotics, blood serum, plasma protein and so on many kinds of bacteria in the solution;

( 5) Food industry: beverage, wine, soy sauce, vinegar and so on in food suspended muddy thing, microorganism and odor removal of impurities, yeast and mold the juice clarification filtration.

( 6) Chemical industry: all kinds of chemical filter to clarify.
