Congratulations to SSI’s R & D team who have just been awarded a US patent on the use of a pressure sensor inside of a diffuser to digitally measure differential pressure across a membrane and orifice using piezoresistive sensors. In the future, this development will enable us to build smart aeration systems that sense membrane fouling, compare measured values to a series of past values and to neighboring diffusers, and automatically initiate membrane cleaning events. Prior to this development, diffuser pressure has been measured in the field using a series of tubes and analog gauges, with manual tabulation of values.
