BIOAqua Online Dammed Water Quality Analyser

Reservoirs are essential infrastructures in the water management field. The origin of its waters may be diverse (rain, streams, run-off of cultivated land, etc.), not guaranteeing the quality of the environment because these flows may contain large amounts of nutrients, organic matter and other contaminants.

Likewise, the natural behaviour of dams and reservoirs can actively influence the state of the water. The eutrophication state of some dams represents a serious problem for managing the resource. The BIOAqua Online Dammed Water Quality Analyzer system constitutes the most complete solution on the market for automatic monitoring of the quality of dammed water and the optimization of its use.

BIOAqua Online Dammed Water Quality Analyzer is comprised of a multi parameter self positioning probe that automatically measures chemical and physical properties that represent the quality of water at different depths in dams.

This tool is highly effective for managing water in reservoirs, which allows optimizing operating costs and minimizes organoleptic problems in subsequent purification. BIOAqua Online Dammed Water Quality Analyzer ensures quality control in real time and defines the ideal depth at which water is extracted depending on its end use.

BIOAqua Online Dammed Water Quality Analyzer – Operation

Automatic Operation

BIOAqua Online Dammed Water Quality Analyzer carries out automatic measurements of the parameters at different depths in order to develop profiles graphics. The frequency and depth of the measuring points are configurable.

BIOAqua Online Dammed Water Quality Analyzer has a cleaning system that enables the extension of the system’s autonomy.

Data are collected automatically by the control center for their analysis and operation.

Manual Operation

The measurement process is set off by a local order from the BIOAqua Online Dammed Water Quality Analyzer keyboard or by a remote command.
