Sodium Dichloroisocyanurate (SDIC) is a powerful disinfectant renowned for its efficiency in water purification and sanitation. A key factor contributing to its effectiveness is its 'available chlorine' content. Understanding what this means and how it influences the performance of SDIC is crucial for optimizing its use in various applications.

Available chlorine refers to the oxidizing capacity of a chlorine-containing compound. In the case of SDIC, when it dissolves in water, it releases hypochlorous acid (HOCl). It is HOCl that acts as the active sanitizing agent, destroying microorganisms through oxidation. The 'available chlorine' content is essentially a measure of how much HOCl can be released from a given amount of SDIC, indicating its disinfecting potential.

SDIC is typically available with specified percentages of available chlorine, commonly around 56% or 60%. This means that for every 100 units of SDIC, there are either 56 or 60 units of active chlorine available for disinfection. A higher available chlorine content generally translates to a more potent disinfectant, requiring a smaller amount of product to achieve the desired level of sanitation.

For water treatment, the concentration of available chlorine is critical for effective disinfection. Too low a concentration might not be sufficient to kill all pathogens, while too high a concentration could be wasteful, potentially corrosive, or even pose health risks if not managed properly. Therefore, selecting an SDIC product with an appropriate available chlorine content for the specific application is important.

For instance, in swimming pool maintenance, the target free chlorine residual is typically between 1-3 ppm (parts per million). When using SDIC, knowing its available chlorine percentage helps in calculating the exact amount of product needed to achieve and maintain this residual level. Similarly, for drinking water purification, precise dosing based on the available chlorine content is vital to ensure safety without imparting an unpleasant taste or odor.

The stability of SDIC ensures that its available chlorine content remains consistent over time, unlike liquid hypochlorites which lose their potency more rapidly. This reliability in maintaining active chlorine levels makes SDIC a preferred choice for applications demanding predictable disinfection performance.
