1.What is Smart diffuser in wastewater treatment?
An air diffuser or membrane diffuser is an aeration device typically in the shape of a disc, tube or plate, which is used to transfer air and with that oxygen into the sewage or industrial wastewater. Oxygen is required by microorganisms/bacteria residents in the water to break down the pollutants.
2. Smart Disc Diffuser Working Principle:
① The membrane bulges and slits open during aeration by Mthe pressure of compressed air. The support plate distributes the air evenly over the entire surface of the membrane. Air is spread into small bubbles when released through the membrane.
② When the airflow is turned off, the pressure of the water above presses the membrane disc tightly to the support plate closing the small slits on the membrane. The non-return valve closes and makes sure that no water enters the pipeline.
