📚 Quick Study Guide

  • 💧 Definition: Filtration is a separation technique used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but retains the solid.
  • Everyday Examples: Coffee brewing, water purification, air conditioning filters, kidney dialysis, and vacuum cleaners.
  • ⚗️ Key Concepts: The driving force behind filtration is usually a pressure difference across the filter. This can be achieved through gravity, vacuum, or applied pressure.
  • 📏 Filter Medium: The choice of filter medium depends on the size of the particles to be removed. Common materials include paper, sand, membranes, and cloth.
  • 🔬 Industrial Applications: Wastewater treatment, chemical processing, pharmaceuticals, and food and beverage production all rely heavily on filtration.
