How often does the sand filter need to be replaced?

There are two types of sand filters.

  1. High-rate sand filters - It usually needs to be replaced every 2-5 years.
  2. Low-rate sand filters - Low loading rate can last longer than the high-rate sand filters.

Replacement of the sand filters depends on the different loading rates and the organic content in the wastewater. For example, wastewater rich in organic material needs to be maintained better and reduces the performance of the sand filter.
