Long-term field tests confirm that IQ-50 maintains accuracy for over a year without any cleaning, delivering unmatched reliability for continuous operation. Turbidity Sensor Module (WP-4000) Until recently, real-time turbidity measurement at the household level was nearly impossible. The WP-4000 module changes that. Based on custom semiconductors, this ultra-compact sensor can operate over 10 years maintenance-free , while being much more cost-efficient than traditional sensors. This breakthrough addresses a critical issue: studies show that 25% of household water purifiers may degrade water quality by releasing contaminants during filtration. With WP-4000, consumers and manufacturers gain access to real-time water quality data at the tap — ensuring that purified water is truly clean. Add-on Type(PipeTalk™) ※ Under Development Aging water distribution networks, micro-leakage, and biofilm buildup are common challenges in water supply systems worldwide.Currently under development, PipeTalk™  utilizes real-time turbidity data to detect early signs of anomalies within pipelines, enabling predictive and preventative maintenance . By shifting from reactive response to proactive management , PipeTalk™ enables the transition toward smart, preventive water network operations .This represents more than just monitoring — it’s a step toward a sustainable and resilient water management system . In addition, PipeTalk™ provides real-time membrane integrity monitoring for each vessel , detecting abnormalities in membrane filtration units (MF/UF, NF/RO) and minimizing fouling or damage.The system continuously collects data after backwash, filtration, and permeation stages , allowing operators to gain a comprehensive overview of membrane integrity across the entire process  — ultimately maximizing operational efficiency and membrane lifespan. Conventional turbidimeters require regular cleaning, calibration, and skilled operation. In contrast, The.Wave.Talk ’s technology delivers world-class accuracy while operating maintenance-free for over five years.

Evaluations by leading global home appliance manufacturers  have also confirmed that the sensor maintains stable performance under harsh conditions such as pressure, vibration, temperature fluctuations, and humidity — setting a new benchmark for long-term stability and operational efficiency across both public and industrial sectors. In-line Bacteria Measurement Device ※ Under Development (PoC with LG Display) Building upon its expertise in turbidity measurement, The.Wave.Talk  is expanding into the field of real-time bacterial detection.Through a Proof of Concept (PoC)  with LG Display , the company is developing the world’s first inline bacteria measurement device  capable of simultaneously detecting turbidity and bacteria. This product is based on The.Wave.Talk ’s technology that received NET (New Excellent Technology) certification in 2025  — “High-speed detection of foreign particles and microorganisms in purified water using deep-learning algorithms.” The technology has been officially recognized by the Korean government for both its technical excellence and commercialization potential. The device achieves a detection limit of 100 CFU/mL  and operates 40 times faster than traditional culture-based methods , offering 100,000 times higher resolution  than conventional optical tools.It introduces a new standard for microbial monitoring in industries requiring extreme precision and hygiene, such as semiconductor manufacturing, pharmaceuticals, biotechnology, and food production. Traditional bacterial analysis methods rely on culture-based processes that take 24–48 hours  and require trained personnel and laboratory facilities.In contrast, The.Wave.Talk ’s deep-learning–powered technology  can identify bacteria much faster with exceptional accuracy. Validated through KOLAS certification, government testing, and clinical trials at Severance Hospital , the system demonstrated 100% accuracy  and the capability to distinguish bacterial concentrations as low as 0.1%. Compared to FDA-certified systems , it also exhibited superior sensitivity and specificity. Conventional bacterial and particle measurement systems depend on manual procedures, periodic maintenance, and long analysis times (often over 24 hours). The.Wave.Talk ’s sensor is the world’s first to enable real-time, simultaneous, and fully automatic measurement of both bacteria and particles. By combining proprietary optical signal amplification  with AI-based speckle signal analysis , the system reduces maintenance requirements by up to 50 times  and shortens analysis time by 40 times , providing results within 30 minutes. With over 100 patents filed  and 80 registrations completed , this breakthrough technology establishes a new generation of intelligent, efficient, and economically scalable water quality monitoring platforms.

By developing an ASIC (Application-Specific Integrated Circuit)  that integrates the CMOS camera and MCU —the core components of conventional water quality sensors— THE WAVE TALK  has achieved an unprecedented level of miniaturization. This semiconductor-level integration not only reduces the overall sensor footprint but also enhances stability, signal processing efficiency, and production scalability. In parallel, we designed a custom laser drive circuit  and a miniaturized laser module  to ensure stable optical output and improved performance, even in compact configurations. This allows for high-sensitivity turbidity and bacterial detection  without the need for bulky optical assemblies or frequent maintenance. Thanks to these innovations, our ultra-compact water quality sensor  can now be seamlessly deployed across all water-related touchpoints—from industrial infrastructure such as pipelines and membranes  to smart home appliances  requiring real-time, autonomous water quality monitoring.

Membrane filtration facility at Aewol Water Treatment Plant, Jeju (Reference material, source: Seoul Economic Daily) From Conventional Sedimentation to Advanced Membrane Filtration Traditional sedimentation-based water treatment plants rely on coagulation, sedimentation, and filtration to remove suspended solids and impurities. While this method is simple and well-proven, it requires large land areas, significant chemical usage, and costly sludge management—making it less efficient and sustainable in terms of space and operation. In contrast, membrane filtration  physically separates fine particles, pathogens, and even microplastics using membrane barriers. This advanced process ensures consistent turbidity control and high-quality water output. Compact design and ease of automation make it particularly suitable for urban and small-scale plants. However, membrane systems still face challenges such as high operational costs and energy consumption . In large-scale facilities, varying raw water quality, frequent chemical cleaning, and increased power demand make it difficult to achieve both efficiency and economic feasibility. The Global Shift Toward ‘Smart Operations’ Across the globe, water utilities and industrial plants are moving toward Sustainable Operation  and Smart Maintenance . Rather than focusing solely on new membrane materials, the industry is turning toward data-driven optimization , collecting and analyzing operational data in real time. At the center of this transformation lies precision turbidity monitoring . Turbidity is not just a measure of water clarity; it reflects membrane fouling, cleaning cycles, and overall energy efficiency .To improve reliability, plants must acquire stable, accurate turbidity data that remain unaffected by biofilm, bubbles, or pulsation —while minimizing maintenance. The Solution: High-Precision Turbidity Monitoring In membrane filtration, turbidity changes directly indicate variations in membrane fouling and pump pressure . Real-time precision monitoring therefore plays a critical role in optimizing plant performance. Key benefits include: Optimized cleaning cycles:  Reducing unnecessary chemical cleaning saves both chemical and operational costs. Energy savings:  Early detection of fouling prevents excessive pressure loss. Localized diagnostics:  Vessel-level integrity monitoring enables early anomaly detection. Ultimately, precision turbidity monitoring enhances efficiency, cost-effectiveness, and reliability —the three pillars of successful membrane plant operation. TheWaveTalk Testbed — Data-Driven Operations Begin with Inline Turbidity Monitoring TheWaveTalk  is currently conducting a testbed program at domestic membrane filtration plants using its AI-powered inline turbidity meter  (automatic continuous turbidity measurement system). This initiative goes beyond simple water quality measurement—it aims to demonstrate how real-time data can optimize plant operation by analyzing turbidity behavior before and after membrane cleaning , assessing long-term data stability , and identifying signal variability trends . Testbed Overview Location:  Domestic water treatment plant Focus areas:  Real-time detection accuracy, cleaning response, signal stability In the next phase, TheWaveTalk plans to extend its technology to vessel-level integrity monitoring  by applying miniature turbidity sensor modules to each membrane vessel. This will enable module-level anomaly detection and efficiency tracking , accelerating the digital transformation of water treatment plants . Online Membrane Integerity Monitoring for Every Vessel Conclusion Membrane filtration represents the future of advanced water treatment , but without operational efficiency, it cannot become a truly sustainable solution. By delivering stable and intelligent turbidity data , The.Wave.Talk  is pioneering the digitalization of membrane operations —bridging the gap between advanced purification and sustainable practice. Organizations or partners interested in our membrane turbidity sensor testbed  or technical collaboration  are welcome to connect with us. Together, we can define the next standard of efficient, intelligent water treatment . 📧 Contact us: marketing@thewavetalk.com

Turbidity: The Core Indicator of Water Quality Turbidity—the cloudiness caused by fine particles or impurities suspended in water—is one of the most critical indicators of pool water quality. It determines not only how “clear” the water looks but also affects hygiene, safety, and operational efficiency . As turbidity rises, disinfectant efficiency declines, filtration load increases, and underwater visibility decreases, creating potential safety hazards. Many countries recommend maintaining pool turbidity within 0.5–5 NTU  for optimal clarity and safety. More importantly, turbidity is recognized as the earliest indicator of water quality anomalies . Changes in turbidity often precede bacterial growth, organic buildup, or declining filtration performance. This makes real-time turbidity sensing the most direct and reliable tool  for proactive water quality management. Modern turbidity sensors are no longer just instruments for clarity—they have become predictive devices  that detect invisible signs of contamination before they escalate. ※ Reference: Mike Sadar, “ Turbidity Measurement: A Simple, Effective Indicator of Water Quality Change ,” Hach Hydromet Application Notes , 2017. The Barriers: Cost and Maintenance Despite its importance, turbidity monitoring remains underutilized in many facilities due to three key challenges: High equipment cost:  Precision instruments are often too expensive for small or mid-sized pools. Complex maintenance:  Optical sensors are easily affected by biofilm, scale, or bubbles , requiring frequent cleaning and calibration. Dependence on specialists:  Many facilities lack the trained personnel to maintain continuous, reliable operation. As a result, many operators rely on manual inspections or periodic sampling , leaving a gap between measurement and real-time control. Technology Innovation: Semiconductor-Based Modular Sensors To overcome these barriers, TheWaveTalk  has developed a semiconductor-based miniature modular turbidity sensor . By integrating the latest advances in miniaturization and semiconductor fabrication, turbidity measurement is evolving from a standalone instrument  to an embedded sensing component  within broader systems. Key technological advantages: No biofilm cleaning required:  Optical structure minimizes contamination and maintenance. Auto-calibration:  Maintains long-term stability without manual recalibration. Low-cost semiconductor design:  Enables mass production and cost efficiency. Compact form factor:  Easily integrates into inline systems, circulation loops, or smart devices. In short, TheWaveTalk has redefined the paradigm with a “maintenance-free miniature turbidity sensor.” This innovation enables affordable, real-time monitoring  even in small facilities and residential pools where traditional devices were impractical. A Market Shift Toward Automation and Integration Globally, the pool industry is rapidly adopting automated water quality management .To improve operational efficiency, regulatory compliance, and user safety, integrated systems now combine pH, chlorine, ORP, and turbidity sensors  into unified control platforms. As automation expands, demand is rising for compact, low-cost, and auto-calibrating sensors , designed for seamless integration into filtration or control units.Solution providers are also moving beyond hardware—offering data-driven analytics and operational services , forming the foundation of smart pool management platforms . Where Robotics Meets Water Quality To date, no commercial pool-cleaning robot has featured a built-in turbidity sensor.This has largely been due to sensor size, cost, stability, and maintenance limitations . With TheWaveTalk’s miniature turbidity module, those barriers are gone.Its biofilm-resistant optics, auto-calibration function, and maintenance-free operation  allow for integration into cleaning robots. Future robotic pool cleaners could evolve from simple cleaning tools into smart autonomous systems —detecting contaminated areas, optimizing cleaning routes, and adjusting operation based on real-time turbidity data.This represents the first step toward a fully integrated model  that unifies mechanical cleaning and intelligent water management. Proven Reliability and Commercialization The.Wave.Talk ’s semiconductor-based turbidity sensor has already passed multi-year validation with a global home appliance leader , leading to a technology licensing agreement.This demonstrates that its accuracy and stability are verified not only in laboratories but also under real-world operating conditions . TheWaveTalk: Redefining the Standard for Water Quality Management The.Wave.Talk ’s modular turbidity sensor redefines traditional instruments—once seen as expensive and maintenance-heavy —into a compact, affordable, and integrable solution . With maintenance-free design , auto-calibration , and real-time data connectivity , the sensor is emerging as a core component of next-generation smart water management systems . This technology empowers pool operators to efficiently manage filtration backwash timing, detect circulation blind spots, and optimize chemical dosing—all through continuous data-driven insights.

The.Wave.Talk ’s laser-based inline turbidity meter (continuous turbidity analyzer) IQ-50  has demonstrated exceptional measurement stability  even under such demanding conditions, setting a new standard for turbidity management. 1. Pulsation Test – Consistent Measurements Despite Flow Variations KTR Certified Test Results (Pulsation Conditions) In pulsation condition tests jointly conducted with KTR, the IQ-50 maintained highly stable performance , with readings shifting only slightly from 0.031 NTU → 0.036 NTU  and the Relative Standard Deviation (RSD)  staying low at 2.19% → 5.57% . In comparison, conventional turbidity meters  under the same conditions showed significant fluctuations, jumping from 0.021 NTU → 4.144 NTU , with the RSD  surging from 14.31% → 34.96% . These results clearly show that the IQ-50 provides reliable and accurate data , even in environments where flow variations are frequent. 2. Bubble Test – Accurate Monitoring Despite Bubble Interference Jointly tested and validated with KTR In tests replicating environments with bubble interference, the IQ-50 once again demonstrated stability, maintaining readings at 0.040 NTU → 0.045 NTU  and an RSD  of 3.38% → 4.23% . By contrast, conventional turbidity meters  recorded notable instability, rising from 0.020 NTU → 0.077 NTU , with the RSD  jumping from 8.90% → 26.51% . This validates how the IQ-50’s optical signal amplification and multi-scattering analysis technologies  effectively suppress bubble-induced noise to ensure precise, real-time monitoring. 3. Maintenance-Free, Cost-Effective Design The IQ-50 is designed for direct inline installation  without the need for additional components such as constant-flow pumps, tanks, or bubble-removal devices.

CSMS™ and AI-Powered Next-Generation Precision Sensor Until now, most industry experts would have answered: “That’s impossible.” The reason is clear. Conventional inline sensors cannot detect subtle turbidity changes below 0.01 NTU, and bacterial detection is only possible at very high concentrations. Because of these technical limitations, using turbidity sensors to proactively identify risks in ultrapure processes has been virtually unthinkable. But TheWaveTalk has broken this paradigm by developing an ultra-precision turbidity sensor capable of detecting even the slightest changes—down to 0.0001 NTU—in real time.  The way ultrapure water management is done is about to change. The Breakthrough Technology: CSMS™ At the heart of this innovation lies TheWaveTalk’s proprietary CSMS™ (Chaotic Scattering Material and Structure) . By amplifying laser light pathways through the sample, CSMS™ captures even the faintest scattering signals that conventional sensors fail to detect. “It all comes down to the ultra-fine turbidity range” – The performance gap TWT Sensor (Blue): ✅ Responds precisely down to 0.0001 NTU ✅ Differentiates even minute changes caused by trace contaminants in ultrapure water Laboratory-grade precision turbidimeter (Red): 🚫 Flattened response below approximately 0.02 NTU 🚫 Unable to distinguish in the sub-0.01 NTU region Optimized for Ultrapure Industries ✅ Semiconductor & Display:   Maintaining nano-process yields and preventing micro-contamination ✅ Pharmaceutical & Biotech:   Sterility management and bioreactor contamination prevention ✅ Fine Chemicals:   Real-time detection of ultra-low particle and bacterial contamination Pushing the Limits of Detection Even Further TheWaveTalk has already surpassed industry limits with its 0.0001 NTU precision. Yet, we are not stopping here—we are preparing the next leap forward with even more advanced LoD (Limit of Detection)  capabilities. We invite you to stay tuned for what’s next.

TheWaveTalk recently participated in the 2025 Water and Wastewater Advancement Strategy Seminar  (hereafter referred to as the “Water Management Seminar”). The event was filled with the energy of numerous municipal water officials and corporate representatives, matching the heat of the summer weather outside. Since August 2024, TheWaveTalk has been collaborating with Korea Environment Corporation (K-eco) through the Mutual Growth and Performance Sharing Program . As part of this initiative, we installed our inline turbidity monitoring system at the Pyeongchang Waterworks and conducted extensive field testing over six months. During this time, we identified and addressed on-site challenges, fine-tuned our system, and successfully secured stable, reliable data. This effort culminated in April this year with the system obtaining official certification from Korea’s Ministry of Environment. In addition, we achieved national New Excellent Technology (NET)  certification, a testament to the technological excellence of our solution. The Water Management Seminar provided an ideal platform to showcase the successful partnership between K-eco’s extensive expertise and TheWaveTalk’s innovative technologies. Turbidity—an essential parameter indicating water quality—plays a critical role in ensuring the safety of drinking water. But how thoroughly is turbidity being managed with technologies developed in Korea? Regrettably, more than half of the turbidity analyzers currently installed in domestic water treatment plants and municipal water facilities are imported. Even many devices labeled as “domestic” depend heavily on foreign technologies for core functionalities To address this challenge, TheWaveTalk and K-eco set a clear mission: achieving the localization of turbidity analyzers used in Korea’s drinking water production process. This collaboration led to the development of Korea’s first 100% homegrown inline turbidity monitoring system, utilizing patented technology from the Korea Institute of Science and Technology (KIST). From left: TheWaveTalk Co-CEO Kyungman Cho, Director Gukhyun Nam, K-eco Gangwon Regional Office Head Changwan Choi, and Pyeongchang Waterworks Officer Wongyu Lee This system boasts a localization rate of 94.5% for components (based on material costs) and is the first in Korea to employ a laser light source. The laser-based turbidity analyzer, certified by the Ministry of Environment, marks a breakthrough in the domestic market. Compared to traditional tungsten lamp-based systems, the laser light source extends replacement intervals by more than three times, significantly reducing maintenance requirements. Moreover, the system achieves world-class accuracy while remaining unaffected by biofilm formation, ensuring robust and reliable operation . Notably, its cost is approximately half that of major foreign competitors, as reported on leading industry price information platforms. During the seminar, we were deeply encouraged by the genuine interest and thoughtful discussions from municipal officials who visited TheWaveTalk’s booth. Among them was Changwan Choi, Head of K-eco’s Gangwon Regional Office, who personally stopped by to share insights. With the success achieved at Pyeongchang as a starting point, we are optimistic that The.Wave.Talk ’s inline turbidity monitoring systems will be deployed not only across Gangwon Province but also nationwide, and worldwide—driving the localization of drinking water quality management.
