What is the diaphragm distillation?

membrane distillation is a process used to separate or clean liquids. This technology works by creating a gradient temperature over a membrane, with one side warmer and the other side cooler. The vapors rising from a heated liquid pass through the membrane into the lower pressure of the lower pressure, where they condense into the cleaning form of the liquid. This type of distillation has an application in industrial plants where certain liquids must be separated from the mixture and desalination plants where fresh water must be obtained from salt water. The heat causes the liquid molecules to gain energy and rise in steam. An example of this is steam that rises from hot water. The type of membrane used by this distillation process allows you to go through only steam and eliminate other impurities. After the steam passes through the membrane, it encounters a cool area or a surface that causes it to condense back to the liquid state. The resulting liquid consists only of the molecules that were in steam and any salt or otherNo impurities are still in the original mixture.

There are several types of membrane distillation processes. The distillation of the direct contact diaphragm, which is commonly used in desalination, keeps the cooling solution in contact with the remote side of the membrane. Distillation of the membrane of the air gap separates the coolant from the membrane with a gap and a hard surface on which the steam can condense. Other types of processes, such as sweeping gas and vacuum membrane distillation, actively stretch steam with a membrane using gas or vacuum. These latest techniques are vying for removal of undesirable compounds from the original mixture.

The use of membrane distillation is diverse. It can be used to remove salt and other unrealistic dirt from water, but is also useful in removing specific chemicals or creating concentrated mixtures for industrial or commercial use. As steam distilled with a membrane is odstrAny from the original mixture, so this original mixture is more concentrated.

The membrane distillation has become a desired desalination solution because it requires a relatively low amount of energy for operation. It can be operated by solar heat or waste heat from other operations. The small amount of heat required for this process makes it possible to create small plants in distant areas that may not have access to extensive energy sources.
