Biochemical Disinfection Mechanism & Key Technological Advantages
- Peak Active Chlorine Concentration (≥ 90.0%): Representing the highest available chlorine potency among solid sanitizers, TCCA hydrolyzes rapidly into high concentrations of uncharged hypochlorous acid (HOCl). Due to its electrical neutrality, HOCl effortlessly permeates bacterial cell membranes, inactivating essential intracellular metabolic enzymes and destroying pathogenic micro-organisms at minimal dose rates.
- Controlled Slow-Dissolving Matrix (5–7 Days): Mechanically compressed under intense hydraulic pressure, each 200g tablet dissolves erosion-style over 5 to 7 days under standard water circulation. This delivers continuous, steady free chlorine levels (1.0 – 3.0 ppm) without requiring daily manual chemical dosing, substantially minimizing operational labor.
- Innate Photolysis Resistance (Cyanuric Acid Stabilization): The dissolution process naturally releases cyanuric acid molecules, which act as a solar UV filter. This protective bonding prevents solar ultraviolet rays from decomposing active free chlorine in outdoor pools, saving up to 60% in chemical replenishment compared to unstabilized hypochlorites.
- Heavy-Duty UN-Certified 50kg HDPE Drum: Molded from thick-walled virgin white high-density polyethylene, each drum features an airtight threaded lid and dual handles. Designed to withstand mechanical impact and prevent ambient moisture ingress, it completely suppresses hazardous chlorine odor migration during transit and storage.
Practical Applications in Water Sanitization & Biosecurity
Backed by robust oxidizing action and long-lasting persistence, trichloroisocyanuric acid 90 serves critical water treatment sectors:
- Commercial & Residential Swimming Pools:
• Dosed inside surface floating dispensers, skimmer baskets, or offline erosion feeders.
• Maintenance Protocol: Apply 1 tablet (200g) per 40 – 50 m³ of pool water every 5 to 7 days. Maintains a steady chlorine residual of 1.0 – 3.0 ppm, keeping pool water crystalline and preventing green, yellow, and black algae build-up on walls and floors. - Commercial Aquaculture & High-Tech Shrimp Farming:
• Thorough disinfection of reservoir pond water and pond bottom sanitization prior to post-larvae stocking.
• Completely eradicates pathogenic Vibrio bacteria (AHPND/EMS and white feces syndrome vectors), fungal spores, and microsporidia (Enterocytozoon hepatopenaei - EHP). - Industrial Cooling Towers & Recirculating Systems: Suppresses bio-slime, algal growth, and hazardous Legionella pneumophila bacteria in heat exchange circuits, inhibiting microbially induced corrosion (MIC) and maintaining thermodynamic efficiency.
- Agricultural Livestock & Municipal Effluent Disinfection: Sanitizes animal housing, drainage gutters, and seafood packing facilities; provides terminal disinfection for municipal and hospital wastewater treatment systems.
Technical Dosing Guidelines, Safe Handling & Storage Protocols
- Routine Pool Sanitization Protocol:
• Place 200g tablets into an erosion chlorinator, skimmer basket, or floating chemical dispenser. Regulate water flow so each tablet erodes steadily over 5 to 7 days.
• Test free chlorine residual every 2 days using a DPD test kit to ensure levels remain within 1.0 – 3.0 ppm before inserting replenishment tablets. - Critical Precaution for Pool Liners:
• Never throw 200g tablets directly onto pool floors lined with vinyl, PVC membranes, composite coatings, or epoxy paint. Concentrated chemical dissolution at the bottom will aggressively bleach and embrittle synthetic liners. - Strict Chemical Incompatibility:
• Never mix TCCA directly with other chlorinating compounds (such as Calcium Hypochlorite 70% or liquid Sodium Hypochlorite). Direct cross-contact causes violent exothermic reactions, high gas pressure, and explosion hazards. - Warehouse Storage Protocol:
• Keep drum lids tightly sealed after use. Store elevated on pallets in a cool, dry, well-ventilated dedicated warehouse out of direct sunlight.
• Strictly isolate from heat sources, lubricants, fuels, strong reducing agents, mineral acids (HCl, H₂SO₄), and ammonium compounds.
⚠️ CHEMICAL SAFETY ADVISORY (GHS CLASS 5.1 OXIDIZING SUBSTANCE - UN 2468, PG II):
• Hazard Characteristics: Strong oxidizer. Generates corrosive, choking chlorine gas upon contact with atmospheric moisture. Always stand upwind when opening the drum lid.
• Mandatory Personal Protective Equipment (PPE): Personnel must wear chemical splash goggles, heavy-duty rubber gloves, and an acid gas/organic vapor respirator with activated carbon filters.
• Emergency First Aid: In case of contact with skin or eyes, flush immediately with copious clean water for at least 15 minutes. In case of inhalation, evacuate victim to fresh air immediately and seek medical attention with the product MSDS.

Frequently Asked Questions (FAQ)
1. Why choose slow-dissolving TCCA 200g tablets over daily granular chlorine dosing?
Granular hypochlorite dissolves instantly and degrades rapidly under solar UV exposure, necessitating daily manual testing and dosing. TCCA 200g tablets dissolve slowly over 5 to 7 days while providing built-in cyanuric acid UV stabilization, ensuring continuous residual sanitization and lowering operational overhead.
2. Does TCCA 90% tablet application cause pool water pH to rise?
No. A 1% aqueous solution of TCCA has a slightly acidic pH (2.6 – 3.2). Unlike alkaline calcium hypochlorite, TCCA does not elevate water pH or cause cloudy calcium scale formation, making overall water balancing significantly simpler.
3. Why must 200g tablets never be dropped directly onto vinyl-lined or coated pool floors?
Direct contact generates an intense, localized chlorine concentration on the surface as the tablet erodes. This localized hyper-chlorination bleaches pool paint, discolors vinyl liners, and causes permanent embrittlement. Tablets must always be placed inside floating dispensers, skimmers, or inline feeders.
4. Does THP Chemical provide batch COAs and VAT invoices for 50kg drum orders?
Yes. THP Chemical supplies batch-specific factory Certificates of Analysis (COA), 16-section MSDS sheets, and legal commercial VAT invoices with every shipment, ensuring complete technical and regulatory compliance for facility audits.
