Trichloroisocyanuric Acid (TCCA) used for swimming pool

Currently, disinfectants used in swimming pools were as bellow: 
Bleach, bleach water (sodium hypochlorite), chlorine, trichloroisocyanuric acid (TCCA). Bleach: it is sodium hypochlorite, calcium chloride and calcium hydroxide mixture as a white to off-white powder or granules. Significant chlorine smell, nature is very unstable, hygroscopic, susceptible to moisture, light and heat to break down, can also react with the air of CO2. Aqueous alkaline solution available chlorine release component, oxidation, sterilization, bleaching, but there is sediment, water surface with a layer of white floating debris, the gastrointestinal mucosa, respiratory tract, skin irritation, and can cause coughing and affect vision . Dosage: each approximately 1000m3 20 ~ 30Kg. 
Trichloroisocyanuric Acid (TCCA), also called strong acid, a white crystalline powder, also processed into granules, flakes, organic chlorine disinfectant and difficult to break down in a dry environment 1 year, only its chlorine content reduced by 1%, TCCA almost entirely in the form of hypochlorous acid hydrolysis process, hypochlorous acid is a strong oxidant, can make pathogenic bacteria protein oxidation denaturation of death, because hypochlorous acid molecule is small, penetration ability, therefore, its bactericidal effect is high, it was determined, at the same concentrations, bleach water disinfection force is stronger than 80 to 100 times.In addition, TCCA efficacy of long duration, a disinfectant oxygen can increase the oxygen content of the water, after launching the advantages of instant precipitation. Dosage per m32 ~ 3 grams.
Instructions of Trichloroisocyanuric Acid (TCCA):
1. swimming pool disinfection: calculate the usage according to 2-3g / m3; take effect for 30-60 minutes. 
2. Public places and ground disinfection: use 1500-3000-fold diluted water solution for spraying and wiping for 30 minutes. Infectious disease epidemic area, use 150-200-fold aqueous diluted water solution for spray disinfection.
3. disinfection of white clothing and blankets: apply 2000-3000 fold diluted solution for clean items; soak for 10 minutes; for seriously polluted items, diluted 500 times, soak for 20 minutes.
4. disinfection of bathroom and toilet scrub; use 300-fold diluted solution for reaction of 30 minutes.
5. sterilization of non-metallic medical equipment: use 500-1000 times diluted solution for soak of 30 minutes; disinfection of apparatus with pus and blood; apply 100-fold diluted water solution for reaction of 30 minutes.
6. disinfection of non-metallic tableware: use 500-1000 times diluted water solution for reaction of 30 minutes.
