Filtreleme, or filtering, is a process used to separate substances based on specific criteria. It is commonly applied in various fields, such as water purification, where unwanted particles are removed from water to make it safe for consumption. The technique can also be used in data analysis to sift through large datasets, allowing users to focus on relevant information. In everyday life, filtreleme can be seen in actions like using a coffee filter to separate coffee grounds from liquid. This simple method illustrates how filtering can enhance the quality of a product, whether it’s a beverage or information, by removing impurities or irrelevant data.
