vollfiltration

Vollfiltration, also known as total filtration, is a process used in various industries to remove all solid particles from a liquid. This is achieved by passing the fluid through a filter medium that has a pore size small enough to capture all particulate matter. The goal of full filtration is to achieve a highly clarified or even sterile liquid, depending on the application.

The specific type of filter medium used in vollfiltration depends on the nature of the liquid and the size of the particles to be removed. Common materials include membranes, cartridges, or specialized filter cloths. The pore size rating of the filter is critical and is typically measured in microns. For complete removal of all solid particles, including very fine ones, filters with very small pore sizes are employed.

Vollfiltration finds applications in pharmaceuticals, where sterile filtration is essential for drug production. It is also used in the food and beverage industry for clarifying liquids like wine, beer, and juices, ensuring clarity and stability. In electronics manufacturing, high-purity water is often subjected to full filtration to remove any contaminants that could damage sensitive components. Water treatment plants also utilize full filtration techniques to produce potable water. The efficiency of vollfiltration is often measured by the amount of material removed and the clarity or purity of the final filtrate. Pressure is typically applied to drive the liquid through the filter, and the rate of filtration can be influenced by factors such as viscosity, temperature, and the filter's surface area.
