N2O Liquid Phase Monitoring Devices

Supply of liquid-phase nitrous oxide (N₂O) monitoring equipment and associated calibration equipment for use at Yorkshire Water wastewater treatment sites. The equipment will provide continuous monitoring of dissolved N₂O concentrations and temperature within activated sludge process lanes and includes sensor probes, controllers, calibration equipment, associated accessories and manufacturer support.

Equipment must be supplied directly by the original equipment manufacturer and is required to enable the collection of N₂O monitoring data for baseline establishment and operational performance assessment. The equipment must support continuous data collection, integration with telemetry and control systems, and operation in accordance with Yorkshire Water's specified technical and environmental requirements.

Equipment will be supplied to 13 wastewater treatment sites. The quantity of sensors, controllers and associated equipment required will vary by site in accordance with the site-specific design and monitoring requirements.

Installation and commissioning will be undertaken by Yorkshire Water, or through a separately contracted delivery partner under an existing framework agreement.
