Bio-Purge, biofilm control


If you are noticing that your diffusers are releasing fewer and fewer bubbles then likely a biofilm is forming a coating that is restricting airflow by blocking the perforations.

Bio-Purge is our leading cleaning/maintenance product for underwater air diffusion systems including aeration discs and Bubble Tubing™. As with any aeration product, over time, air diffusers and bubble tubing benefit from a maintenance treatment to remove calcium deposits, or organic biofilm that may coat the surfaces and inhibit airflow.

Bio-Purge is a maintenance products designed to clean aeration lines and diffusers.  Biofilm develops slowly covering the small holes designed to release micro-bubbles of air. Factors such as temperature, water quality, water hardness, pH and air pressure all effect if or when a biofilm may form, which explains why there are instances when no biofilm develops, or biofilm develops rapidly.
