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.
- Fast Dissolving Powder Morphology: Unlike slow-dissolving tablets, the fine powder formulation dissolves rapidly upon pre-mixing in water. It releases maximum oxidizing power within minutes, making it ideal for immediate shock treatments, sudden algae remediation, and acute water biosecurity interventions.
- 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 rapid dissolution, trichloroisocyanuric acid 90 powder serves critical water treatment sectors:
- Commercial & Residential Swimming Pool Shocking:
• Designed for rapid pool shocking (super-chlorination) following heavy thunderstorms or heavy bather loads to eliminate green, yellow, and black algae.
• Recommended Dosage: Apply 1.5 – 3.0 g of TCCA powder per 1 m³ (1,000 Litres) of water. Pre-dissolve in a bucket of clean water and broadcast around the pool perimeter with the circulation system running. - Commercial Aquaculture & High-Tech Shrimp Farming:
• Thorough disinfection of reservoir pond water and pond bottom sanitization prior to post-larvae stocking.
• Recommended Application Rate: Apply 15 – 20 kg per 1,000 m³ of water in reservoir ponds; run paddlewheel aerators continuously for 3 to 5 days to eliminate pathogenic Vibrio bacteria (AHPND/EMS and white feces syndrome vectors), fungal spores, and microsporidia (Enterocytozoon hepatopenaei - EHP) before stocking. - 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
- Mandatory Dissolution Protocol (Pre-mixing):
• Always adhere strictly to the rule of adding small quantities of TCCA powder into a bucket filled with clean water, stirring thoroughly with a plastic rod before broadcasting.
• Never pour water directly into dry powder to prevent violent exothermic decomposition, boiling splashing, and hazardous gas emissions. - Critical Precaution for Pool Liners:
• Never broadcast undissolved powder directly onto pool floors lined with vinyl, PVC membranes, composite coatings, or epoxy paint. Concentrated chemical settling 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. Fine chemical dust generates corrosive, choking chlorine gas upon contact with atmospheric moisture. Always stand upwind when opening the drum lid and measuring powder.
• 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. What is the difference between TCCA 90% powder and 200g tablets?
TCCA 200g tablets are hydraulically compressed to dissolve slowly over 5 to 7 days for routine daily background chlorination. TCCA powder dissolves rapidly to release active chlorine immediately, making it the superior choice for shock dosing, algae blooms, and fast pond reservoir disinfection.
2. Does TCCA 90% powder 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 TCCA powder never be broadcast dry onto vinyl-lined pool floors?
Undissolved powder settling directly onto vinyl liners or epoxy coatings produces hyper-concentrated bleaching and aggressive oxidation at the contact point, causing discoloration and liner embrittlement. Always pre-dissolve the powder in clean water before distributing.
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.
