A filtration system is a process used to separate solids from liquids or gases by using a filter. This system can be found in various applications, such as water purification, air quality control, and industrial processes. The filter material captures particles while allowing the fluid to pass through, ensuring cleaner output. Different types of filtration systems exist, including mechanical filters, chemical filters, and biological filters. Each type serves specific purposes, such as removing contaminants from drinking water or filtering air in HVAC systems. Proper maintenance of these systems is essential for optimal performance and longevity.
