Solution | Water Quality Monitoring Solution for River and Sea

INTRODUCTION

Automatic water quality monitoring at river and sea discharge outlets is one of the key technologies for environmental protection and management. By enabling automatic monitoring, this solution ensures effective oversight of existing pollution discharge points, allowing for real-time data collection, quick response to water quality issues, and effective measures to improve the ecological quality of river and marine environments. River and sea discharge outlets are crucial, as they are the final gateways for pollutants to enter rivers and seas, making them primary sources of water pollution. Thus, enhancing automatic water quality monitoring at these points is a significant step toward improving water ecosystem quality.

THE DIFFICULTY AND SITUATION OF RIVER AND SEA DISCHARGE OUTLETS

Numerous outlets make it challenging to inspect thoroughly.

Few monitoring points make rapid detection difficult.

Lack of smart monitoring limits predictive alerts and traceability.

Pollution tracing is challenging, making it difficult to hold responsible parties accountable.
