Trichloroisocyanuric acid (TCCA) is an organic compound with the formula (C3Cl3N3O3).This white crystalline powder, which has a strong "chlorine odour," is sometimes sold in tablet or granule form for domestic and industrial use. Salts of Trichloroisocyanuric acid (TCCA) are known as trichloroisocyanurates.

The Trichloroisocyanuric acid (TCCA), with the CAS registry number 87-90-1,is also known as 1,3,5-Trichloro-1-triazine-2,4,6(1H,3H,5H)-trione; 1,3,5-Trichloroisocyanuric acid; Symclosene. It belongs to the product categories of Chlorination;Halogenation;Synthetic Organic Chemistry;Biocide.Its EINECS number is 201-782-8. This chemical's molecular formula is C3Cl3N3O3 and molecular weight is 232.41. What's more,Its systematic name is Trichloroisocyanuric acid (TCCA).It is a white to light yellow crystal powde which is stable,hygroscopic, and incompatible with acids,reducing agents,water,strong oxidizing agents.And it may lead to fire when Contact with combustible material. Trichloroisocyanuric acid (TCCA) is used for disinfection of drinking water, swimming pool water, industrial circulating water, sewage and any other water.It is usually used as an industrial disinfectant, bleaching agent and an organic synthesis reagent.

Trichloroisocyanuric acid (TCCA) applications

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 industry. It is widely used in civil sanitation for pools and spas, preventing and curing diseases in animal husbandry and fisheries, fruit and vegetable preservation, wastewater treatment, as an algicide for recycled water in industry and air conditioning, in anti shrink treatment for woolens, for treating seeds and in organic chemical synthesis.

Trichloroisocyanuric acid (TCCA) as used in swimming pools is easier to handle than chlorine. It dissolves slowly in water, but as it reacts, cyanuric acid concentration in the pool will build-up. At high cyanuric acid concentrations, normal chlorine levels can be rendered ineffective, requiring either dilution by draining and refilling the pool or by adding abnormally high doses of chlorine to overcome this effect.


Use of Trichloroisocyanuric acid (TCCA)
1. TCCA can be used in water treatment, especially in swimming pool water treatment, drinking water treatment, algae removal from industrial water supplies, treatment of industrial or city sewage, disinfection of petroleum well drilling slurry and sewage, and production of seawater cells.

2. It can be used in dishware disinfection, preventative disinfection of houses, hotels and public places, hygiene and disease control in hospitals, and environmental disinfection for fish, silkworm, livestock and poultry keeping. Trichloroisocyanuric acid(TCCA) can also be used in the disinfection and preservation of fruits and vegetables..

3. Finally, it can also be used in textile cleansing and bleaching, wool shrink resistance, paper insect resistance, rubber chlorination, etc.

Benefits of Trichloroisocyanuric acid (TCCA) in swimming Pool
TCCA is available with 90% chlorine concentration. Due to the high chlorine content, it is easy to handle for large pools. It reduces chlorine loss during the day time. Trichloroisocyanuric acid (TCCA) is stable and does not strip like many other halogen compounds. It reduces algae growth. TCCA dissolves slowly in water, allowing for continuous, measured dosing of chlorine, especially when in tablet form.

Trichloroisocyanuric Acid (TCCA) for drinking water chlorination
Access to common chlorine generating products (HTH, NaDCC) is limited in Iraq and other Middle-Eastern contexts. Trichloroisocyanuric Acid (TCCA) is available however, marketed for use in swimming pools as 'clean pool 90'. The tablets are 200g, with available chlorine listed as 90% minimum. The dosage would need to be reduced considerably for, say a 10m3 water truck.
My main concern, however, is whether this would be a suitable chemical for the chlorination of drinking water? To an untrained eye it looks similar to the Sodium dichloroisocyanurate (NaDCC) used in Aquatabs, but I'm unsure whether any of the bi-products might be hazardous in drinking water.
As a slow release tablet the proposal would be to use this in a floating pot chlorinator.Any guidance would be very much appreciated.
