What was awarded for the Santillana Drinking Water Plant?
Longking EnTech Europe was awarded the contract to supply and commission a new 90 kg O₃/h ozonation system for the Santillana Drinking Water Plant in Madrid, operated by Canal de Isabel II.
The project included a centralized ozone generation system designed to serve both pre-ozonation and intermediate ozonation stages, together with the engineering required for its integration into the existing drinking water treatment plant.
At the time of this contract announcement, the project was entering its execution phase. The installation has since been completed and commissioned.
For the completed installation, system configuration, CFD optimization, automation, cooling and safety architecture, see our Santillana 90 kg/h ozone system technical case study.
What did the Santillana ozone contract include?
The awarded scope covered the engineering, supply, installation, commissioning and start-up of a new 90 kg O₃/h centralized ozonation system for the Santillana Drinking Water Plant.
The project included integration with the plant’s existing pre-ozonation and intermediate ozonation stages, together with the auxiliary systems, automation and process engineering required for reliable operation.
A Computational Fluid Dynamics (CFD) study of the existing ozone contact chambers was also included in the engineering scope to evaluate hydraulic behaviour and support optimization of ozone transfer and effective contact conditions.
Detailed information on the final system configuration and the results of the engineering work is available in the Santillana 90 kg/h ozone system technical case study.
What ozone generation capacity was awarded for Santillana?
The awarded system was designed with a total installed ozone production capacity of 90 kg O₃/h, based on 3 × 30 kg O₃/h Longking NLO ozone generators operating with oxygen as feed gas.
This configuration was selected to provide the capacity and operating flexibility required for the plant’s pre-ozonation and intermediate ozonation stages.
Further technical details on the final configuration, contact chamber optimization, cooling, ozone destruction, automation and SCADA integration are available in the Santillana 90 kg/h ozone system technical case study.
How was remote monitoring included in the Santillana contract?
The awarded system included integration of Longking EnTech Europe’s SENTINEL remote monitoring platform, providing access to key operating parameters, alarms and system status to support troubleshooting and maintenance activities.
Remote access remains subject to the plant’s cybersecurity requirements and operating policies.
For a detailed description of the final automation, SCADA integration and monitoring architecture, see the Santillana 90 kg/h ozone system technical case study.
What was the context of the Santillana ozone contract award?
Santillana is one of the major drinking water treatment plants operated by Canal de Isabel II in the Madrid region. The 90 kg O₃/h contract represented a significant modernization of the plant’s existing ozonation infrastructure and reinforced the use of ozone within its multi-barrier drinking water treatment process.
At the time this contract was announced, installation works were underway and commissioning was planned for 2022. The project has since been completed and the new ozonation system is now part of Longking EnTech Europe’s municipal drinking water reference portfolio.
This article records the original project award and execution milestone. For the completed installation—including the final 3 × NLO30 configuration, CFD optimization of the contact chambers, ozone destruction, cooling, automation and SCADA integration—see the Santillana 90 kg/h ozone system technical case study.
