82. Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China 6/17/2016

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

83. Memosens 2.0: Cutting-Edge Sensor Technology Reloaded 8/3/2021

    Memosens technology converts the measured value to a digital signal and transfers it inductively to the transmitter. With signal alarms in the event of transmission disruption, Memosens offers safe data transfer for increased availability of the measuring point and trouble-free processes. With Memosens 2.0, measuring points become completely future-proof and ready for IIoT.
