Cleaning the membranes

To prevent the membranes from fouling it is strongly recommended to clean the membranes periodically.

The most common techniques are:

• Running the diffusers with the maximum overload airflow (air bumping) for a short period of time.
• Inject formic acid into the airflow
• Flush the whole system with acid or alkaline solution
• Dewater the tank and blow off the fouling with an high-pressure water jet
