When Milk Is Ultrafiltered To Extract Milk Fat And Protein, Permeate Is A By-Product

Permeate 

 

Permeate is a term used in various fields such as chemistry, biology, and engineering. It refers to the substance or component that passes through a semipermeable membrane from a high concentration area to a low concentration area, either by diffusion or osmosis. In simpler terms, permeate is the material that passes through a filter or membrane, leaving behind the substances that cannot pass through.

The term "Permeate" is often used in the context of filtration processes. Filtration is the process of separating substances by passing them through a porous material, such as a membrane or filter. This process is commonly used in water treatment, where contaminants are removed from the water to make it safe for consumption. In this context, permeate refers to the purified water that passes through the membrane or filter, leaving behind the contaminants.

Permeate is also used in the field of biology. In cellular biology, the cell membrane is selectively permeable, meaning that it allows certain molecules or ions to pass through while blocking others. The molecules or ions that pass through the membrane are referred to as the permeate, while those that are blocked are referred to as the retentate.

In chemistry, Permeate refers to the component that has passed through a semipermeable membrane in a process called dialysis. Dialysis is a process that separates small molecules from larger ones by using a semipermeable membrane. The small molecules, or permeate, pass through the membrane and are collected on the other side, while the larger molecules, or retentate, remain on the original side.

Humans raise tamed birds called Poultry for their eggs, meat, or feathers. Most frequently, these birds belong to the superorder Galloanserae (fowl), particularly the order Galliformes. The phrase also refers to birds that are killed for their meat, such as juvenile pigeons (squabs), but excludes comparable wild species that are hunted for sport or sustenance and are referred to as game birds.

Permeate is also used in the context of reverse osmosis. Reverse osmosis is a process that removes impurities from water by forcing it through a semipermeable membrane. In this process, the purified water that passes through the membrane is referred to as the permeate, while the impurities that are left behind are referred to as the concentrate or brine.
