In developed nations, trust in tap water is still a concern, despite significant investments in treatment systems. Our innovative laser and semiconductor-based sensor is designed to change that. With zero maintenance for 10 years, it's small enough to be built into smart water meters. Our sensor uses advanced light scattering technology to detect impurities and bacteria in real time, even at low concentrations. By integrating this into smart meters, companies can monitor water quality at the pipeline's end, ensuring safer, proactive water management. Watch the video to see how we're redefining water quality monitoring for the future.

This video is part of The Wave Talk’s in-house project, the Digitized Water Project (DWP). Using our advanced water measurement technology, the project aims to provide valuable insights to help society access cleaner water. Starting with this video, the DWP will span several series, during which we will develop prototype products and conduct various experiments to ensure cleaner water across different sectors. Staying true to The Wave Talk’s mission, we hope to make it possible for more people to drink and use clean, pure water. The turbidity of the water used prior to filtration in this experiment was 0.40 NTU. Please note that the results may vary depending on the quality of the water used.

Curious about the challenges of delivering safe drinking water to every home? Our latest white paper dives deep into the "Last Mile Problem" and how the world’s first deep learning sensor-on-a-chip  is revolutionizing water quality monitoring. Download the full white paper to explore how we're tackling these issues and ensuring safer water for all.

The results of comparing our product with a competitor's product after installation at a water treatment plant for approximately 13 months without any maintenance, including cleaning. The measurement values showed no difference from the competitor's product, and when the turbidity increased in the competitor's product, our product exhibited the same tendency to increase. The scale effect results below confirm that even after a year without cleaning or maintenance, the formation of internal scale did not affect the measurement results. This characteristic is due to our unique measurement method, which offsets the scale effect in turbidity measurements, allowing for long-term operation without maintenance.
