- Definition filtration technique in which a layer of a filter aid (e.g. diatomaceous earth) is applied to the surface of a filter, forming a filter bed that captures impurities Reference "COM-EN, based on:- Faudi > Precoat filtration: Efficient filtration solution for your application (3.3.2025)- Matex YG > How Diatomite Filtration Works: A Comprehensive Guide (3.3.2025)"
- Comment Precoat filters are used when the dirt particles are too small to produce their own filter cake. The filter cake is created by means of a precoated filter aid on the filter cartridge. The fine particles are filtered out through this precoat layer, i.e. the filter cake. When the maximum dirt holding capacity of the filter cake is reached, it is rinsed off the filter cartridge.
