HTH stands for what in water disinfection?

Explanation:
HTH stands for high-test hypochlorite, a granular calcium hypochlorite disinfectant used in water treatment. The “high-test” label indicates a higher available chlorine content than standard chlorine products, enabling effective disinfection at appropriate dosages. In practice, this form of calcium hypochlorite (Ca(OCl)2) provides a strong, rapid source of chlorine when added to water. The other options don’t fit the term: it isn’t hydrogen, nor “hypochlorous test,” nor a hydrogen-based version of hypochlorite.
