Media vs Membrane: How to Choose the Right Stormwater Filtration Solution

May 12, 2026

Since the passage of the Clean Water Act in 1972, stormwater filtration systems have improved significantly. Two categories of filters—media and membrane—remove pollutants in different ways. In this Ask the Experts feature, we explore the differences between them and when to use each. You'll discover:

  • Media filter stormwater solutions: How and why media filters work, how they can be adjusted to capture specific stormwater runoff pollutants, and how to maintain media filters.
  • Membrane filtration: What a membrane is, how it works, membrane filtration maintenance, and what kinds of stormwater treatment BMPs membrane filters can help you achieve.
  • Stormwater pollutant removal methods: How to tell which filtration option is right for your application, the standards with which these filtration systems should comply, how often to complete maintenance procedures for each, and what you can expect from these particle removal tools.
