Industrial Process Water — Sanitises recirculating systems in manufacturing, food & beverage processing, and wash-down operations
Cooling Towers & HVAC Systems — Controls microbial growth (including Legionella risk) in open and closed-loop cooling systems
Potable Water Storage & Emergency Treatment — Treats tanks, cisterns, wells, and rainwater harvesting systems
Other Uses — Drill rigs, remote camps, construction site water, remediation projects, and spill response

General Instructions for Safe & Effective UseMaintain appropriate free chlorine residuals based on your specific application (typically 0.5–5 ppm depending on purpose and regulations).

Pre-Treatment Testing — Always test water quality (chlorine, pH, cyanuric acid) before dosing. Keep cyanuric acid below 50–100 ppm depending on system requirements.
Dosing Guidance — Dosage varies widely by application, flow rate, and target residual. As a starting reference: 1 × 150g stick can treat approximately 15,000–25,000 litres depending on demand and contact time. Always calculate based on system volume, flow, and required chlorine residual.
Placement — Use in purpose-designed tablet feeders, contact chambers, or gravity-feed erosion devices. Ensure good water flow across the sticks.
Monitoring — Regularly measure free chlorine, pH, and system performance. Adjust stick quantity or feed rate as needed.
Safety Precautions — Wear appropriate PPE (gloves, eye protection) when handling. Store in a cool, dry, well-ventilated area away from incompatible materials. Do not mix with other chemicals. In case of contact, rinse thoroughly and seek medical attention if irritation persists.
Regulatory Note — Always follow local water treatment regulations, dosing guidelines, and discharge standards.

Dosing Rates & Guidelines

All dosing rates below are indicative and based on standard Australian industry practice. Actual dosing must be determined by site-specific water quality testing, regulatory requirements, and risk assessment. One 150 g stick contains approximately 135 g of available chlorine (90% w/w).

Application	Target Free Chlorine Residual	Indicative Dosing Rate	Units	Notes
Residential swimming pool — maintenance	1.0–3.0 mg/L (ppm) free Cl₂	Approx. 1 × 150 g stick per 50,000–70,000 L per week	sticks/week	Use in floating feeder or in-line erosion feeder. Adjust for bather load, temperature and cyanuric acid level. Maintain cyanuric acid (CYA) 30–50 mg/L.
Commercial / public swimming pool — maintenance	1.0–3.0 mg/L free Cl₂ (SPASA / state health dept.)	Dose via calibrated erosion feeder; approx. 2–5 g available Cl₂ per m³ per day depending on bather load	g available Cl₂/m³/day	Feeder flow rate must be calibrated. CYA must not exceed 100 mg/L in public pools. Check state public health pool regulations.
Swimming pool — superchlorination / shock	Raise to 10 mg/L free Cl₂ then allow to fall below 5 mg/L before bathing	Approx. 10–15 g TCCA per 1,000 L (1 m³)	g/m³	Pre-dissolve in a bucket of pool water before addition. Do not use TCCA for superchlorination if CYA already exceeds 80 mg/L — use unstabilised sodium hypochlorite instead.
Spa pool — maintenance	3.0–5.0 mg/L free Cl₂	Approx. 3–5 g available Cl₂ per 1,000 L; use ¼ stick (approx. 37 g) per 2,000 L as a guide	g/1,000 L	High water temperatures accelerate chlorine demand. Monitor closely. CYA build-up is a concern in high-turnover spa environments — dilution is the solution.
Cooling towers — continuous dosing	0.2–0.5 mg/L free Cl₂ residual at outlet	0.5–2.0 g available Cl₂ per m³ of circulating water per day	g/m³/day	Must comply with AS/NZS 3666.2 and state health department risk management plans. TCCA adds CYA which may interfere with some residual monitoring methods — validate analytical method.
Cooling towers — shock / remedial dosing	2–5 mg/L free Cl₂ for minimum 1-hour contact time	Approx. 2–5 g available Cl₂ per m³	g/m³	As per AS/NZS 3666.3 remedial disinfection procedures. Isolate drift eliminators where required. Record all dosing events.
Potable water storage tank — shock chlorination	5–10 mg/L free Cl₂; allow 30-minute contact time then flush	Approx. 5.5–11 g TCCA per 1,000 L (1 m³)	g/m³	Pre-dissolve before dosing. Flush thoroughly before returning to service. CYA accumulation must be managed in ongoing treatment. Check local authority requirements. Note: AS/NZS 4020 compliance of feeder equipment required for drinking water contact.
Recycled / irrigation water disinfection	0.5–1.0 mg/L free Cl₂ residual at point of use	1.0–3.0 g available Cl₂ per m³	g/m³	Dosing rate highly dependent on chlorine demand of treated water. Jar testing and residual monitoring recommended prior to commissioning.
Wastewater / effluent tertiary disinfection	Meet discharge licence requirements (typically 1–2 mg/L residual after 30-minute CT)	5–20 g available Cl₂ per m³ (highly variable; depends on BOD/COD of effluent)	g/m³	Bench-scale chlorine demand testing essential. High organic loads will consume chlorine rapidly. Consider chlorine contact time (CT value) requirements of the relevant environment protection licence.
Equipment and surface sanitation (solution)	50–200 mg/L available Cl₂ in working solution	Dissolve approx. 55–220 mg TCCA per litre of water	mg/L	Prepare fresh each day. Do not use on aluminium, copper or brass surfaces. Minimum 1-minute contact time on clean surfaces. Rinse food-contact surfaces thoroughly after use.

Dilution Instructions

Important: Trichloroisocyanuric acid is a powerful oxidiser. Always handle in a well-ventilated area. Never add water directly to solid TCCA — always dissolve TCCA into a large volume of clean water. Never mix with other chemicals in concentrate form.

Don PPE before commencing: Put on chemical-resistant gloves (nitrile minimum 0.4 mm, neoprene or butyl preferred for extended contact), chemical splash goggles, and an apron. If preparing solutions in enclosed spaces or handling quantities greater than 500 g, wear a P2/Class B combination respirator.
Select appropriate equipment: Use a clean, dry HDPE or polypropylene bucket or dosing vessel. Never use metal containers. Ensure the vessel is free from contamination — even residues of incompatible chemicals (see Chemical Compatibility section) can cause dangerous reactions.
Fill the vessel with clean, cool water first: Add the required volume of clean water to the vessel before adding any TCCA. Water temperature should ideally be below 25°C. Do not use hot water — this accelerates dissolution and chlorine gas evolution.
Add TCCA slowly to the water: Place the required number of sticks or weighed quantity of TCCA gently into the water. Never pour water onto dry TCCA tablets. Stir gently with a chemical-resistant paddle or rod.
Allow to dissolve fully: TCCA sticks are designed to dissolve slowly. For preparing working solutions, allow adequate time for complete dissolution (typically 15–30 minutes for a 150 g stick in 10 litres of water at 20°C). Do not crush sticks to accelerate dissolution unless specifically required — crushing increases dust and chlorine gas hazard.
Verify concentration before use: Use a calibrated DPD chlorine test kit or photometer to verify free available chlorine (FAC) concentration in the prepared solution before application. Record the result.
Dose immediately or use within 24 hours: Prepared chlorine solutions degrade rapidly, particularly in sunlight. Store prepared solutions in a sealed, opaque HDPE container and use within 24 hours. Label all prepared solutions with date, time, and concentration.
Dispose of unused solution correctly: Do not return unused solution to the original drum. Dilute heavily with water and dispose to sewer in accordance with local trade waste regulations, or allow to dechlorinate naturally in an open, ventilated area before disposal.

For in-line erosion feeders and floating dispensers: Load tablets or sticks directly into the feeder per the manufacturer’s instructions. Ensure the feeder is designed for TCCA — not all feeders are compatible. Never mix TCCA sticks with other tablet types (e.g. calcium hypochlorite pucks, bromine tablets) in the same feeder. Never leave a TCCA feeder in a stagnant, non-circulating water system.
