AI Deep Learning Sensor-on-a-chip for Turbidity & Bacteria

The Future of Water Quality Monitoring, All in One Platform

From water treatment membranes to swimming pools, home water purifiers, smart appliances, and even ultrapure water in precision industries — reliable water quality monitoring has become essential everywhere. Yet until now, the market lacked ultra-compact, cost-effective turbidity sensors capable of delivering high-precision measurements for years without maintenance.

The.Wave.Talk is redefining this landscape by mass-producing next-generation turbidity sensors that work seamlessly across all applications, setting a new standard for water monitoring.

1. In-line Turbidity Meter (IQ-50)

Designed for municipal and industrial facilities, the IQ-50 Inline Turbidity Meter integrates directly into pipeline systems for real-time monitoring. Operators no longer need separate sampling processes or external devices — turbidity data is available instantly for immediate response. Its maintenance-free and auto-calibrating design ensures stable performance without frequent checks, making it an ideal solution for public utilities operating with limited manpower and budgets. Long-term field tests confirm that IQ-50 maintains accuracy for over a year without any cleaning, delivering unmatched reliability for continuous operation.

2. 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.

3. 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.

Tested and certified by KOLAS and verified by government agencies, the system meets drinking water standards with proven precision and reproducibility.

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.

4. 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.
