Ship Exhaust Gas Cleaning System (EGC) Water Quality Monitor

The ship exhaust gas cleaning water quality monitoring system consists of sensor cabinets, electronic units, air purification systems, integrated circulation pumps, pressure reducing valves, and flow meters. It is used to monitor the seawater quality at the inlet and outlet, obtain water quality monitoring data to determine whether the discharged water meets the standards. The sensor cabinet can monitor parameters including polycyclic aromatic hydrocarbons (PAH), turbidity, temperature, and pH, and the data is transmitted to the central control system through Ethernet connection. The UviLux fluorescence sensor is configured in the system to meet special requirements for PAH and turbidity monitoring, with turbidity measurement complying with the ISO7027:1999 international standard.
