Thermal stratification in potable water storage tanks poses risks for system operators and their customers. Water treated with chlorine or chloramines generally remains stable for a few days. Thermal stratification can hamper passive mixing or cycling of the water resulting in the potential for limit aging or deterioration of the disinfectant chemicals. Drops in residual chlorine can lead to growth of bacteria often requiring the draining and flushing of the tank.
Thermal stratification can also promote the formation of nitrates and other disinfection byproducts, allow for the formation of ice endangering coatings and tank walls and allow headspace temperatures to rise above recommended levels.
The HydroView Pro 5MWI is equipped with depth and temperature sensors. Data from these sensors is recorded during tank inspections and downloaded following the inspection in an easy to read/report format. Additional water chemistry sensors are available and can be integrated with the vehicle and the data reporting module.
