For a green hydrogen plant using river water as cooling water, key parameters to monitor

 For a green hydrogen plant using river water as cooling water, key parameters to monitor and control include temperature, pH, total dissolved solids (TDS), suspended solids, and conductivity, ensuring they remain within acceptable limits to prevent corrosion, scaling, and ensure efficient cooling system operation. 

Here's a more detailed breakdown:

Temperature:

Maintaining a suitable temperature range is crucial for efficient cooling and preventing damage to equipment. 

pH:

A stable pH level helps prevent corrosion and scaling in the cooling system. 

Total Dissolved Solids (TDS):

High TDS can lead to scaling and corrosion, so it's important to keep it within acceptable limits. 

Suspended Solids:

Excessive suspended solids can clog cooling system components and reduce efficiency. 

Conductivity:

High conductivity indicates a high concentration of dissolved ions, which can lead to corrosion and scaling. 

Other Parameters:

Depending on the specific plant design and location, other parameters like turbidity, hardness, and the presence of specific ions (e.g., chlorides, sulfates) might also need monitoring and control. 

Water Treatment:

To ensure the cooling water meets the required quality, appropriate treatment methods, such as filtration, softening, and demineralization, might be needed. 

Water Source:

The specific limits for cooling water parameters will depend on the characteristics of the river water source and the specific requirements of the green hydrogen plant's cooling system. 

Regulations:

Local environmental regulations and standards also need to be considered when establishing the limits for cooling water parameters.
