Brief introduction:

Filter membrane, typically used for separating solutes in solution and enriched, also commonly used in the separation of colloidal suspensions.
Water membrane treatment is kind of solid-liquid separation technology, which is based on the membrane pore water filtration, the impurities in the water retention, and no chemical change,  simple application techniques.

The species:

Filter membrane with raw water trapped particle size classification, from crude membrane pores to be subdivided into microfiltration membrane (MF), ultrafiltration (UF), nano filtration membrane (NF) and reverse osmosis (RO).

MF membrane pore size 0.05um or more, or a molecular weight of 1,000 or more to remove colloids, organic polymer for the object.

NF membrane pore size of 100 to 1000 molecular weight. It is the removal of the material between the UF and RO, to remove trihalomethanes, odor, color, pesticides, dissolved organic matter, Ca, Mg, etc.

RO separation particle diameter of several tens of molecular weight, in order to remove salt and inorganic salt as the object class.

RO permeate water pressure more than osmotic pressure to 1 to 2 times. In addition to these four, there is an ion exchange membrane and the gas-permeable membrane.

MF, UF, NF and RO pressure-driven solid-liquid separation. Ion exchange membrane electric drive places make salt molecular separation, contributed to desalination.

Gas permeable membrane is a new study out of the film through the gas, make ethanol concentration and desalination.
Ultrafiltration, microfiltration membrane, nanofiltration, microfiltration membranes, hollow fiber ultrafiltration membrane, membrane, etc. Purcell.

At present, the most widely used ultrafiltration membrane, the membrane in the form of press, mainly divided roll, plate and frame, tubular and hollow fiber membranes and the like.

The main feature:

Membrane filtration device without using chemical flocculation treatment, nor do they need evaporation separation, just so that the water pressure liquid separation membrane filtration process which is a major feature.

Application :

Filter membrane is used in addition to water, but also for the manufacture of ultrapure water and desalination, reverse osmosis membranes in general (Nano filter). In addition to waste treatment, urban waterways handle a variety of wastewater treatment, generally using ultrafiltration and microfiltration membranes. Dairy products can be used in industrial manufacturing, semiconductor manufacturing, food manufacturing, paper manufacturing and pharmaceutical manufacturing, but also the general use of ultrafiltration and microfiltration membranes.
Membranes used in food and beverage, medical and pharmaceutical, municipal water treatment engineering, industrial high water, boiler water, desalination, electronics industry ultrapure water, wastewater treatment and reuse, material concentrated purification and other industries.
More extensive, household water purifiers ultrafiltration, ultrafiltration membrane. Macromolecules in solution can be removed, colloids, proteins, particles, etc., with the use of low pressure, large water production, easy to operate features.
