Minimizing Downtime through Predictive Maintenance, Backwashing Optimization, and Real-Time Quantitative Bacteria Monitoring
Overview of the Ultrapure Water Process
The ultrapure water (UPW) production process involves multiple treatment steps to achieve an exceptionally high level of water purity, and it plays a key role in various industries, including semiconductor, pharmaceutical, power plant, and secondary battery production. By applying TheWaveTalk’s ultra-small turbidity and bacteria sensors to this process, one can maximize both efficiency and reliability.
By utilizing TheWaveTalk’s advanced sensors in the processes highlighted with yellow boxes—namely Reverse Osmosis, Ultrafiltration, and TOC (Total Organic Carbon) removal lines—the performance of the ultrapure water system can be further enhanced.
The Challenge: Ensuring Stable Ultrapure Water Supply Amidst Climate Change
Climate change significantly affects the availability and quality of water resources, posing a major threat to the stable supply of ultrapure water. Extreme weather events—such as droughts and floods—destabilize the feed water supply, while rising sea levels and pollutant infiltration degrade water quality, reducing the efficiency of ultrapure water production processes. As a result, industries heavily dependent on ultrapure water, including semiconductors, pharmaceuticals, power plants, and secondary batteries, face growing risks in maintaining stable production and product quality.
In particular, these industries experience direct operational risks due to changes in water resource stability. The semiconductor industry requires stringent contamination control for its ultra-fine fabrication processes; the pharmaceutical industry relies on ensuring product quality through stable ultrapure water supplies; power plants depend on ultrapure water to maintain equipment efficiency; and the secondary battery industry needs ultrapure water to ensure optimal battery performance. However, the uncertainty in water resources caused by climate change threatens the stable production of these industries as a whole. Ultimately, the issue of securing ultrapure water is directly linked to the uncertainties in water resources driven by climate change, making new approaches and technological innovations essential to address this challenge.
The Solution: Advanced Ultrapure Water Management with Turbidity and Bacteria Monitoring Sensors
To overcome the challenges posed by climate change and water quality management, applying TheWaveTalk’s advanced sensor technology to the ultrapure water process can maximize efficiency and stability. This solution introduces groundbreaking improvements at critical stages of ultrapure water production, enhancing process performance and achieving cost-effectiveness.
RO Process – Real-Time Integrity Testing and Predictive Maintenance By integrating ultra-small turbidity sensors into RO systems, the integrity of RO membranes can be monitored in real time. The sensors conduct automated tests based on precise data, enabling predictive maintenance. This approach prevents membrane performance degradation in advance, extends equipment lifespan, and reduces unnecessary maintenance costs. It provides a core technological foundation for ensuring a stable supply of ultrapure water.
UF Process – Optimizing Backwashing Intervals In the UF process, ultra-small turbidity sensors measure the turbidity of water at both the inlet and outlet of each UF module in real time. The collected data is utilized to optimize backwashing intervals, thereby reducing unnecessary water and energy consumption and minimizing process downtime. As a result, overall operating costs decrease, while the efficiency of ultrapure water production increases.
TOC Process – Real-Time Quantitative Bacteria Analysis By applying TheWaveTalk’s bacterial quantification sensor in the TOC line, it is possible to move away from conventional, inefficient culture-based methods and instead monitor bacterial levels in real time. This technology enables immediate detection and resolution of bacterial contamination issues, allowing for rapid and precise management of ultrapure water quality. It is a groundbreaking solution that overcomes the inefficiencies of traditional bacterial quantification, which previously required more than 24 hours.
In practice, assuming a detection limit (LoD) of 100 cfu/ml with an accuracy of 77%, the measurement time is merely one minute. This essentially means that bacterial levels can be quantified almost in real time. Furthermore, if the goal is to achieve 95% accuracy at concentrations below 100 cfu/ml, results can be obtained within six hours. Compared to the conventional culture-based method, which takes at least 24 hours, this solution offers bacterial quantification in one-fourth or less of the time.
Achieving Industrial Innovation and Sustainability in Ultrapure Water Management
As climate change intensifies and uncertainties in water resources grow, ultrapure water is becoming an indispensable resource for industries such as semiconductors, pharmaceuticals, power plants, and secondary batteries. These industries, which depend on ultra-precise processes and high-quality production, now regard the establishment of an efficient and sustainable ultrapure water management system as a critical necessity rather than an option.
TheWaveTalk’s ultra-small turbidity sensors and bacteria monitoring sensors significantly improve the overall efficiency of ultrapure water management processes. They offer an innovative solution that can reduce operating costs and enhance process reliability for various industries. Real-time monitoring, predictive maintenance in RO and UF processes, and rapid bacterial detection in TOC processes help maximize productivity, minimize downtime, and reduce both energy and resource consumption.
In conclusion, these technological innovations open up opportunities for ultrapure water-dependent industries to respond more effectively to climate change and water resource scarcity. This advancement transcends simple process improvements by setting new standards for achieving sustainable competitiveness in the global market and driving industrial innovation forward. TheWaveTalk’s sensor technology establishes a new paradigm for ultrapure water management systems and plays a pivotal role in supporting the future-oriented growth of each industry.
