Guide to Reliable Water Quality Data with Semiconductor-Based Turbidity Sensors

Why is Real-Time Turbidity Monitoring Essential for Water Purifiers?


Most water purifiers widely used in homes and offices lack real-time turbidity monitoring capabilities. While some purifiers are equipped with TDS sensors, these cannot detect bacteria, microplastics, E. coli, or mold. 

As a result, many consumers still feel uncertain about the safety of their water, even when using purifiers. Just as the saying goes, "If you can’t measure it, you can’t improve it," the water purification industry must prioritize solving this issue.



Global Warning: The Need for Reliable Water Quality Data


The importance of this monitoring extends beyond household water quality management. Recently, major European companies like Siemens, Ecolab, Suez, Veolia, and Xylem issued a joint statement to EU policymakers, warning that the lack of reliable water quality data and standardized measurement systems could undermine water resource resilience. From households to the national level, the need for precise, real-time water quality monitoring systems is becoming increasingly urgent.



The Wave Talk’s Revolutionary Solution: The World’s First Semiconductor-Based Digital Turbidity Sensor

A water purifier functions as a small water treatment plant within the home. In actual water treatment plants, turbidity monitoring is essential; if turbidity exceeds safe levels, water supply is immediately halted. However, due to the high cost and large size of traditional equipment, integrating such turbidity sensors into household water purifiers has been challenging.

To address this, The Wave Talk developed the world’s first semiconductor-based digital turbidity sensor. This innovative sensor allows consumers to monitor water quality in real time, detecting impurities with 1,000 times the precision and 100 times the cost efficiency of conventional sensors. Its compact size enables easy integration into water purifiers. Verified by government testing agencies in South Korea, this sensor has proven its stability and performance, gaining recognition in various markets.

We are entering a new era, transitioning from “purifiers with only filters” to true purifiers equipped with both filters and sensors.



Cost Reduction and Efficient Management: Smart Water Quality Monitoring Powered by IoT and Big Data

Even with identical purifiers, filter contamination rates vary significantly depending on water quality conditions. Traditional purifiers do not account for these differences, resulting in uniform maintenance cycles. This can increase the risk of contamination and lead to unnecessary maintenance costs.


The Wave Talk’s digital turbidity sensor not only provides real-time water quality detection but also delivers a transformative impact on maintenance cost reduction. With a maintenance cycle 40 times longer than traditional turbidity sensors, it reduces the frequency of filter replacement. Integrated with IoT and big data, the sensor predicts filter and valve conditions, guiding users to the optimal replacement timing. This ensures safety and convenience for consumers, while offering maintenance cost savings and asset management efficiency for businesses.



Expanding The Wave Talk’s Technology to the Global Market


The Wave Talk’s digital turbidity sensor has already been successfully implemented in major global appliance manufacturers' water purifiers and is set to be incorporated into various purifier models from global manufacturers by 2025. With increasing demand for water quality monitoring in North America and Europe, 


The Wave Talk is rapidly expanding its market presence, leveraging its technical prowess and cost-efficiency. The success of turbidity sensors in purifiers is set to drive innovation across all sectors of the water industry, from potable water to ultrapure water, leisure water, and industrial water applications.


“If a turbidity sensor can be used in purifiers, it can be applied across all water industries.”



The Wave Talk’s Vision Toward a Global Standard


The Wave Talk’s digital turbidity sensor is establishing a new benchmark across the global water industry. The demand for clean, safe water is unwavering, and The Wave Talk’s technology is meeting that demand.


We look forward to the day when people will say, “Was there ever a time when we couldn’t know the quality of our own water?” Leading this transformation, The Wave Talk is positioned as a pioneer in global water quality monitoring systems.
