Drinking water treatment (controlled alkalinity improves taste and stability). Aquaculture (supports certain fish species that prefer mildly alkaline conditions). Agriculture (used for irrigation in soils that benefit from slightly higher pH). Industrial processes (cooling systems boilers to reduce corrosion).

Prevent corrosion in pipes and systems. Maintain chemical stability of water. Support biological processes that require mild alkalinity. Enhance effectiveness of some treatment processes (like disinfection).

Slightly alkaline water. Low concentration of hydrogen ions. Common in natural waters with dissolved minerals (like bicarbonates).
