The market offers several effective chlorine-based sanitizers, with Trichloroisocyanuric Acid (TCCA) and Sodium Dichloroisocyanurate (SDIC) being two of the most prominent. Both are powerful disinfectants, but they possess distinct chemical properties and application profiles. As manufacturers and suppliers of these critical water treatment chemicals, NINGBO INNO PHARMCHEM CO.,LTD. aims to clarify the differences to help you make an informed choice.

Trichloroisocyanuric Acid (TCCA)

TCCA is known for its high effective chlorine content (typically ≥90%) and its stability due to the presence of cyanuric acid. This makes it ideal for outdoor applications like swimming pools, as the cyanuric acid protects the chlorine from UV degradation. TCCA is generally more acidic than SDIC.

  • Key Features: High chlorine content, UV stabilization, slow-release (especially in tablet form), acidic nature.
  • Primary Applications: Swimming pool sanitization, industrial water treatment, general disinfection.
  • Forms: Powder, granular, and tablets.

When you buy TCCA, you are investing in a highly stable and long-lasting disinfectant, particularly beneficial for applications requiring sustained chlorine levels.

Sodium Dichloroisocyanurate (SDIC)

SDIC, on the other hand, has a lower effective chlorine content (typically 56-60%) and is less acidic than TCCA. It dissolves faster and is often preferred for indoor applications or where a quicker release of chlorine is desired. SDIC is generally considered safer for delicate materials and has a more neutral pH.

  • Key Features: Lower chlorine content, faster dissolution, less acidic, broader pH range for use.
  • Primary Applications: Drinking water treatment, food industry sanitization, general household disinfection, quicker shock treatments.
  • Forms: Powder and granular.

If your requirement involves frequent disinfection with less concern for UV degradation, or if you need a sanitizer with a less aggressive pH, SDIC might be a suitable choice.

Choosing Between TCCA and SDIC

The selection between TCCA and SDIC largely depends on the specific application and environmental conditions:

  • For outdoor swimming pools: TCCA is generally preferred due to its UV stabilizing properties.
  • For indoor pools or where faster sanitization is needed: SDIC might be more appropriate.
  • For drinking water or food processing: SDIC's less acidic nature and broader pH compatibility often make it the preferred choice.
  • For industrial water treatment requiring sustained chlorine levels: TCCA is typically favored.
