Trichloroisocyanuric acid (C3Cl3N3O3), also known as Symclosene, trichloro-s-triazinetrione, TCCA, TCICA, and trichlor, is a chemical compound used as an industrial disinfectant, bleaching agent and a reagent in organic synthesis.[1] [2] This white crystalline powder, which has a strong "chlorine odour," is sometimes sold in tablet or granule form for domestic and industrial use.

[edit] Use in water treatment
The compound is a disinfectant, algicide and bactericide mainly for swimming pools and dyestuffs, and is also used as a bleaching agent in the textile industries.
Applications: It is widely used in civil sanitation, pools and spas, preventing and curing diseases in husbandry and fisheries, fruits and vegetables preservation, wastewater treatment, algaecide for recycling water of industry and air conditioning, anti shrink treatment for woolen, treating seeds, bleaching fabrics, and organic synthesis industry
Benefits of TCCA in Swimming Pool-
- Available with 90% chlorine concentration
- Due to high chlorine content, handling is easy for large pools.
- Reduces chlorine loss during day time. TCCA is stable it does not strip like any other halogen compounds.
- Reduces algae growth as compared to any other disinfectant. It forms a protective blanket on the surface thereby reflecting sunlight back. This prevents algae growth.
- Dissolves slowly in water, allowing for continuously metered dosing of available chlorine, especially when in tablet form.
