In 2018, ZEMING deployed the Zhoushan Marine Meteorological Buoy System for real-time online monitoring of pollution conditions at river estuaries and outfalls. The monitoring parameters include water temperature, pH, dissolved oxygen, conductivity, chlorophyll a, oil content, salinity, turbidity, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, phosphate, as well as meteorological parameters such as air temperature, air pressure, relative humidity, wind speed, and wind direction. This system provides continuous real-time monitoring of the nearby marine environment, hydrology, and meteorology around the Zhoushan Dinghai Wastewater Treatment Plant.
