Whole House Small Scale Water Ultrafiltration Water Treatment Systems：
Ultrafiltration membrane, which is a kind of aperture specification, has a nominal aperture range of 0.01 micron. By placing appropriate pressure on one side of the film, the solute molecules that are smaller than the pore size can be screened to separate particles with molecular weight greater than 500 Dalton (atomic mass units) and particle size greater than 10 nanometers. Ultrafiltration membrane is one of the earliest polymer separation films developed in the 1960s.
The industrial application of ultrafiltration membrane is very extensive and has become one of the new chemical unit operations. Used for separation, concentration, purification of biological products, pharmaceutical products and food industry; It is also used for terminal treatment in blood treatment, waste water treatment and ultra-pure water preparation.
Folding filtration principle：
Ultrafiltration membrane screening process, driven by the pressure difference on both sides of the membrane, ultrafiltration membrane as the filter medium, under certain pressure, when the original fluid flow through the membrane surface, ultrafiltration membrane surface with many tiny pores allow only water and small molecules through and become through the liquid, and concentrate in the volume is greater than the membrane surface micro aperture that substance is trapped in the liquid side of the membrane, liquid becomes, thus achieve the purpose of purification, separation and enrichment of concentrate.
Per metre long silk ultrafiltration membrane on the wall there are about 6 billion 0.01 micron pores, the pore size is only allowed water molecules, the beneficial minerals and trace elements in the water, and the minimum volume of bacteria is above 0.02 micron, so bacteria as well as the volume is much bigger than bacteria colloid, rust, suspended solids, such as sand, macromolecular organic matter can be trapped and ultrafiltration membrane, the purification process was realized.
Its calculation formula is:
S = PI in dL * n
S = PI outside DL * n
Among them: the total internal surface area of the membrane, d is the inner diameter of the ultrafiltration membrane.
Outside of S is the total surface area of the membrane, D is the outer diameter of ultrafiltration membrane;
L is the length of ultrafiltration membrane;
N is the root number of ultrafiltration.
Internal pressure type and external pressure hollow fiber ultrafiltration membrane
Fold the component:
Operating pressure 225psi (1.55 Mpa)
Test liquid temperature 770 F (250C)
Test liquid concentration 2000 mg/L (as NaCl)
Water recovery rate of single membrane components is 15%
Test liquid pH 7
The minimum desalination rate of single membrane elements is 99.0%
Minimum water content of 8,200 GPD (31.0 m3 / d)
Other features of ultrafiltration membrane are as follows:
1) shell impact resistant ABS material, bearing capacity above 16 kg, and 1 mm thick wall thickening, completely can withstand all kinds of the water pressure, to ensure that won't appear rupture phenomenon under the impact pressure, avoid the long-term compression in the process of using ultrafiltration membrane, leaking material produce creep.
2) each of the HUF90 film is filled with 1400 filaments with a length of 100mm, which increases the membrane area by 15% and the effective membrane area is higher than that of any family in the country.
Increased water production.
3) the end cover is the convex structure of the hemisphere. Compared with the traditional plane structure of the end plane, the distribution of the water in the end mask is more uniform and the wall thickness is 1mm thick, so as to ensure that the water pressure is not broken.
4) the adhesion between the shell and the threaded sleeve is used for the bonding of French imported glue. The bonding length is lengthened and the connection clearance is uniform.
There will be no leakage in the process of use.
5) the connection thread of the end cover and the shell USES the serrated thread, which increases the twisting distance and load, and the sliding tooth will not appear.
6) the effective area of the membrane is large, the water flux is large and the pure water flux is 1800 litres, which is much higher than that of the domestic product.
7) the design of pressure resistance and leak-proof structure ensures that the HUF90 ultrafiltration membrane does not leak, degumming, sliding teeth, gluing and other phenomena
Fold the classification
The ultrafiltration membrane is divided into: inorganic film and organic film, and the inorganic film is mainly ceramic membrane and metal film.
The organic film is mainly made of polymer materials such as cellulose acetate, aromatic polyamide, polyether sulfone and polyvinylidene.
According to the shape of the membrane, it can be divided into flat film, tubular film, capillary film, hollow fiber membrane and so on.
The film used in household water purifier is basically hollow fiber membrane.
In the inorganic film, ceramic ultrafiltration membrane is used in household water purifier.
The ceramic film has long life and corrosion resistance, but it has the soil flavor and affects the taste.
Meanwhile ceramic membrane is easy to be blocked, cleaning is not easy.
The hollow fiber ultrafiltration membrane is widely used in household water purification industry due to its large filling density, large effective membrane area, high pure water flux and easy to clean operation.
In the case of constant volume of water per unit membrane, the larger the membrane area is, the more water content of the filter element.
The formula for this calculation is S = PI dL * n S = PI dL * n
Where: S is the total inner surface area of the membrane;
D is the inner diameter of ultrafiltration membrane;
Outside of S is the total surface area of the membrane;
D is the outer diameter of ultrafiltration membrane;
L is the length of ultrafiltration membrane;
N is the root number of ultrafiltration.
