Diffuser Membrane Cleaning System

A reliable solution to clean the diffuser membrane surface without needing to take the aeration tank out of service or interrupting the treatment process.

An atomiser injects an organic descaling liquid along the dropleg. From there the nebulised liquid reaches the diffusers. A dosing pump controls the flow of the descaling liquid, increasing or reducing the flowrate of the descalant to adjust to the membrane condition.
