Keräysteho

Keräysteho is a Finnish term that translates to "collection efficiency" or "capture efficiency." It is commonly used in the context of environmental technology and industrial processes, particularly when referring to devices or systems designed to remove particulate matter or other substances from a fluid stream.

The concept of keräysteho quantifies how effectively a device, such as a filter, electrostatic precipitator, or cyclone, is able to capture or collect the target substance from the gas or liquid it is flowing through. It is typically expressed as a percentage, representing the ratio of the amount of substance captured by the device to the total amount of that substance present in the incoming flow.

A higher keräysteho indicates a more efficient collection process. For example, in air pollution control, a high keräysteho for a particulate filter means it removes a large proportion of dust and other harmful particles from exhaust gases, thus reducing emissions. The factors influencing keräysteho can include the design of the collection device, the physical and chemical properties of the substance being collected, and the operating conditions such as flow rate and temperature. Understanding and optimizing keräysteho is crucial for meeting environmental regulations and improving process efficiency.
