You know that ultrapure water is vital for a laboratory. However, there are multiple water purification methods, and some work better than others. Take a look at the different ways’ labs clean their water and learn how Pure Process Technology can help your ultrapure water needs.
Molecules of contaminants are pulled from the water and absorbed by a porous surface or compound. This method is useful for many uses, but it doesn’t create the ultrapure water a lab might need.
This method uses a resin that pulls ionized salts and minerals out of the water. The ionized particles are drawn to the resin, and this means that only water is left behind. This is a method that is often used in conjunction with other purification methods.
This is one of the oldest methods of purifying water. The water is heated and condenses in a pipe that brings it to a different container. This technique has been used for so long because it is highly effective for many uses.
This method uses a filter to sift through the water and keep contaminants from flowing through it. There are varying sizes of filters which allow for different levels of purification. Filters can be solid, like paper, or a media, such as sand.
This method uses a membrane to separate molecules and particles from water, creating the ultrapure water that many industries need. Pressure is applied to the water, which forces the water molecules through the membrane and leaves contaminants behind.
This is a method similar to filtration but uses a membrane instead of a traditional filter to ensure finer contaminants are processed out of the water.
This method exposes water to UV light, which oxidizes and destroys organic compounds in the water. This is excellent for organic contaminants, but not for inorganic materials. A unique characteristic of UV light is that a specific range of its wavelengths, those between 200 and 300 nanometers (billionths of a meter), are categorized as germicidal – meaning they are capable of inactivating microorganisms, such as bacteria, viruses, and protozoa.
