WALISE – Innovative water quality profiling system for aquaculture and water management

The WALISE system has been designed to provide real-time, automated, and reliable data collection for the management of both natural and artificial water bodies, supporting sustainable and efficient water management.
It is a comprehensive, automated, and profiling solution for continuous water quality observation, forecasting, and intervention management.
One of its key components is the profiling measurement buoy, which can precisely map the vertical structure of water layers (stratification).
This means that WALISE not only collects surface data but continuously monitors the entire water column, providing a detailed picture of thermal, oxygen, and chemical dynamics.
This capability is essential for aquaculture operations, fisheries, lakes, reservoirs, and natural waters, as it enables the prediction of stratification-related oxygen depletion or other critical conditions, allowing for timely preventive action.

Main features and benefits of the WALISE system:

• Real-time autonomous measurement: continuously collects data on key water and air parameters such as dissolved oxygen, pH, temperature, conductivity, and algae concentration.
• Profiling measurement – full water column analysis: the buoy measures at multiple depths, identifying temperature and oxygen stratification and detecting critical zones.
• Early prediction and alerting: the system can warn of potential issues days in advance, predicting changes that could lead to water quality degradation or fish mortality.
• Automated intervention: WALISE can directly control external devices (e.g. aerators, pumps) based on threshold parameters.
• Energy independence: powered by solar energy, ensuring flexible, cost-effective, and sustainable operation.
• User-friendly interface: all data are available in real time via a cloud-based, multilingual web platform, supporting analysis, reporting, and decision-making.
• Durability and reliability: industrial-grade equipment, CE-certified and manufactured under ISO 9001, designed for long-term outdoor use.
• Environmental sustainability: helps protect aquatic ecosystems, contributes to climate adaptation, and the preservation of biodiversity.
