IoT-Integrated Smart Ozone Systems: SCADA, ORP Control and Remote Monitoring
Introduction
Saying “the ozone system is installed and running” is no longer enough. Constantly changing process conditions, flow fluctuations, water quality variations, and the operational requirements of remote facilities are making real-time monitoring and automatic dose control of ozone systems mandatory. IoT integration and SCADA systems are transforming ozone technology from reactive equipment into a proactive process management tool.
In this post we examine what smart ozone systems mean, which parameters need to be monitored, and how real-time data management contributes to system performance. Our 10-chimney integrated SCADA system at Şenpiliç Hendek Factory is one of the most concrete examples of this approach in Türkiye.
Why a Smart Ozone System?
In conventional ozone systems, a fixed dose is applied and the system runs at that dose. But real processes are not static: flow rates change, water temperature changes, organic matter load fluctuates. Fixed dosing in this dynamic environment either falls short (target CT cannot be reached) or overshoots (energy waste, risk of product damage).
IoT-integrated systems solve this problem: ozone dose is automatically adjusted according to real-time data from sensors, the target parameter (ORP, residual ozone concentration, flow rate) is continuously tracked, and deviations are corrected with immediate intervention.
Core Components of a Smart Ozone System
ORP (Oxidation-Reduction Potential) Sensor: Measures the oxidative capacity of the water in millivolts (mV). In water treatment applications, a target ORP range of 650–750 mV represents the optimum balance point between effective disinfection and energy efficiency. The ORP sensor is the most critical feedback element that dynamically adjusts ozone dosing.
Residual Ozone Analyser: Particularly in drinking water, process water, and pharmaceutical applications, direct measurement of dissolved ozone concentration (mg/L) at the outlet point is mandatory for regulatory compliance and process validation.
Flow-Proportional Dose Control: Regardless of flow rate, the ozone dose per unit volume is kept constant. When flow increases, ozone generator capacity automatically rises; when it decreases, it falls. This means both energy savings and consistent disinfection performance.
SCADA Integration: All process parameters — ozone output concentration, oxygen purity, cooling water temperature, ORP, flow rate, energy consumption — are fed into a central SCADA system. Historical data logging, trend analysis, and alarm management can all be monitored on a single screen.
Remote Monitoring and Alarm Management: Operational issues are notified to field personnel via instant SMS/email alarms. Critical events such as ozone generator failure, ORP drop, or residual ozone limit breach can be detected and addressed remotely without requiring physical presence.
The Contributions of Real-Time Data Management
The concrete operational gains of IoT-integrated systems can be summarised as follows: 15–30% reduction in energy consumption (through the transition from fixed to flow-proportional dosing), a marked drop in ozone source losses (precise dosing = less waste), process optimisation through historical data, automation of regulatory compliance reporting, and the opportunity for proactive maintenance against unplanned downtime.
Şenpiliç Hendek: A Real-World Example from Türkiye
At OCS Ozone, we installed an integrated odour elimination and process monitoring system covering 10 separate chimney points at Şenpiliç Hendek Factory. Individual online ozone gas concentration measurement is performed at each chimney point, while a central SCADA system monitors all chimneys in real time from a single screen. With online oxygen (O₂) concentration measurement, a central oxygen generator, and water-cooled central reactor design, the system operates continuously at 1,000 g/hour capacity around the clock. This integration makes independent monitoring of each chimney point and immediate process intervention possible.
In Which Applications Is IoT Integration Essential?
Not every application requires IoT integration; but it becomes essential in the following conditions: pharmaceutical and food processing facilities requiring process validation and GMP/HACCP compliance; drinking water and wastewater treatment plants operating 24/7 at variable flow rates; large-scale industrial systems with multiple application points; and remote or unmanned facilities.
The OCS Ozone Approach
At OCS Ozone, we treat IoT integration not as an optional feature but as a fundamental instrument of process reliability. We plan and deliver ORP control, flow-proportional dosing, and SCADA integration as part of the design phase of the systems we install.
