A few days ago a United Nations study predicts that by 2025, two-thirds of the world's population will be facing a water crisis. Population growth and changes in rainfall patterns will make the ocean as a potential source of drinking water in many countries. But due to huge demand for energy, in the process of seawater desalination technology is still unable to solve the problem of people is imminent. And according to new scientist reported, compared with traditional reverse osmosis technology, the researchers found the alternative energy efficiency is relatively high - — Is penetration technology.
the modern energy consumption effect of reverse osmosis desalination plants than decades ago has improved, but 一座 1 year production. 500 million cubic meters of water desalination plant will consume 90 megawatts, peak output is equivalent to 20 offshore wind turbines. Reverse osmosis is a inner energy intensive process, the process of natural water by light salty, and reverse osmosis process is just the opposite. If high concentrations in seawater injection of absorbing liquid, fresh water can be extracted easily, and this is what some are already starting to appear experimental 'leaking' the principle behind the factory.
hydration technology innovation of companies in the United States ( HydrationTechnologyInnovations) In 2004, introduced a portable water filter is based on the osmosis principle. Is permeable membrane is small, sealed plastic bag, sealed in the package also includes source as absorbing liquid sugar and spices. But the high cost of the filter to produce clean drinking water, can only be used for emergency, thus unable to cope with global water crisis.
is also 2004, the United States by menachem yili miller (Yale university MenachemElimelech) , Jeffrey McCarty piano ( JeffreyMcCutcheon) , Robert McGinnis ( RobertMcGinnis) Team is composed of penetrating ideas to further advance. The team used an absorbing liquid based on ammonium bicarbonate, ammonium ions and bicarbonate ions can attract water molecules through the membrane, and then heating solution to 40 degrees Celsius, ammonia and carbon dioxide discharge, leaving the pure fresh water, and exhaust gas can be reused after capture. Team said, if we can take advantage of the power plant waste heat evaporating gases, the method of energy consumption is only 20% of the desalination plants, but the technology higher requirements for the plant's location.
is infiltration technology faced another challenge is to find the right film, let water through and out of salt. 'Water desalination report' edit Tom carat, pan ( TomPankratz) Said: 'this is the main obstacle is penetrating industry faces. 'Are permeable membrane needs not only the thickness of thin as far as possible, so that the water of the sea close to attract solution, maintain a high osmotic pressure; At the same time also need to be strong enough, but resistance to penetration of water.
hydration technology innovation of the company has developed a cellulose film, the film could not resist ammonium bicarbonate alkaline solution. In order to withstand the high pressure reverse osmosis process, reverse osmosis membrane 'support' is needed to strengthen its toughness, but if used in penetration, the membrane is too thick.
Yale university research team realized that if the support layer to go out, you can get appropriate is permeable membrane. Through the test of different polymer solution, the team found a way to use alternative support layer of thin film method. In addition to the new film, thin and toughness, permeability is very good also. Experiment, up for osmosis membrane flux is traditional 9 times that of the reverse osmosis membrane, can filter 97% of salt. Yili miller said the test USES is 'manual lab version of' the new film, if the new film in industrial scale production, its performance will be better.

Look from the filtering technology consists of nanofiltration, ultrafiltration, sodium filter, reverse osmosis technology. Among them:
1, microfiltration ( MF) : general filtration precision in 0. 1 - 50 microns, such as common all kinds of PP filters, activated carbon filter, ceramic filter and so on all belong to the category of microfiltration, for simple coarse filter, filter the impurities in the water and sediment, rust and other large particles, can't remove the water of bacteria, viruses, organic matter, heavy metal ions and other harmful substances. Usually can not clean, as disposable filter material, often need to change.
　　1) PP cotton filter: high not only commonly used for coarse filtration, removal of water and sediment, rust and other large particulate matter.
　　2) Activated carbon, granular activated carbon filter is widely sold devices in the United States, it is enough to eliminate the peculiar smell in the water and chlorine, but can not effectively remove the water all the toxic chemicals and other pollutants.
　　3) Ceramic filter: small filtering precision can be 0. 1 micrometers can be used in addition to bacteria. But usually small flow rate, not easy to clean. Ultrafiltration (
2, UF) : filtration precision in 0. 001 - 0. 1 micron, belong to one of six new and high technology in the 21st century. Is a kind of using membrane separation technology of pressure difference, can filter out the rust in the water, sediment, suspended solids, colloid, bacteria, viruses, macromolecular organic matter and other harmful substances, and can retain some mineral elements beneficial to human body. Is the core component in the process of synthesis of mineral water, mountain spring. Water in the ultrafiltration process of recovery rate is as high as 95% above. And the realization of easy to rinse with back flush, not easy jam, relatively long service life. The filtering precision of 0. 01 micron ultrafiltration membrane for water rate and the effect of filtering effect is good and is widely used.
3, sodium filter ( NF) : filtration precision between ultrafiltration and reverse osmosis, desalination rate is lower than the reverse osmosis, also is a kind of need electricity, pressurized membrane separation technology, water recovery rate is low. Commonly used in industrial pure water manufacturing.
4, reverse osmosis ( RO) : the filtering precision can reach 0. About 0001 microns, is in the early '60 s developed a high precision using the method of differential pressure of the membrane separation technology. Can filter out the almost all impurities in the water, Including harmful and beneficial) , only to let water molecules through, commonly used in industrial ultrapure water, the manufacture of pharmaceutical ultrapure water and purified water. Reverse osmosis technology need to pressure, with electricity, water utilization ratio is low, not suitable for a large number of domestic and drinking water purification.
common water purification machine on the market at present has the following kinds:
PP filter water purification machine: monocular full of all kinds of PP filter water purification machines, generally low price, but the filter is easy to jam, often need to change, and the filtration precision is not high, only used for the initial filtering of water.
activated carbon filter: can eliminate the peculiar smell in the water and chlorine, but can not effectively remove the toxic chemicals and other pollutants in the water.
pure ultrafiltration water purification machine: can effectively remove the water and sediment, rust, suspended solids, colloid, bacteria, viruses, macromolecular organic matter and other harmful substances, but does not remove the chlorine in water, heavy metal ions, different color and odor.
reverse osmosis pure water machine: completely remove the beneficial and harmful substances in water, the output is softening of desalting water, but do not accord with standard of healthy water. Need to electricity, pressurized water utilization is low ( Waste water rather than pure water. ) , purify the cost is high, the flow rate is small.

PP filter core microfiltration membrane nuclear track etching method PP filter core microfiltration membrane nuclear track etching method is a new method for preparing microfiltration membrane by the dual action of physics and chemistry. By irradiating polymer materials (usually polyester and polycarbonate film materials) with high-energy charged particles (generally about 1MeV intensity), the polymer chain links where the particles pass through are broken to form incomplete tracks. Then, the etching reagent is used to react with the sensitive residual end group, so that the track continues to expand, and finally a columnar hole with uniform pore size is formed, thereby forming a straight through-hole microfiltration membrane. The process of preparing microfiltration membranes by nuclear track etching. The main factors affecting the pore structure of the microfiltration membrane are: the thickness of the film, the irradiation time of the high-energy charged particles, the concentration of the etching solution, the etching time, and the temperature. The thickness of the membrane is generally 5-15um, the pore size of the prepared microfiltration membrane is generally between 0.02-10um, and the porosity is generally about 10%. Because the membrane is thin, the fluid permeation rate is equivalent to the phase inversion method. This film generally has the characteristics of hydrophilicity, heat resistance, acid resistance, and good light transmission. Example Polycarbonate Microporous Membrane Material Acid Carbonate (PC) membrane. Corrosive agent Sodium hydroxide. Film-making process Heavy ions bombard the PC film, and the molecular bonds of the polymer film are broken to form small molecules and free radicals. These excited products continue to be damaged and form acidic compounds under the action of ultraviolet rays/peroxidants; acid compounds are under the action of alkaline solution. , to generate soluble salts, which are washed to form micropores.
