TCCA 90 Granular Product Overview
TCCA 90 Granular (Trichloroisocyanuric Acid, 90% available chlorine) is a stabilized, chlorine-based disinfectant supplied as free-flowing white granules. It is manufactured for use as a primary sanitizer and oxidizing agent in water systems where fast-acting chlorine release is needed.
- What it is: A dry chlorine-donor compound (CAS 87-90-1) that releases hypochlorous acid the active disinfecting agent when dissolved in water.
- What it does: Helps control bacteria, algae and other microorganisms through chlorine-based disinfection.
- Why granular form:The smaller particle size gives more surface area than tablets, so it dissolves faster making it the preferred format for shock dosing and quick chlorine top-ups rather than slow, continuous feeding.
- Who uses it: Pool contractors, facility operators, and distributors who need bulk, consistent-quality chlorine granules for pool and water treatment use.

How to Use TCCA 90 Granular (Usage)?
- Always pre-dissolve granules in a separate container of water before adding to a pool do not add dry granules directly to pool water.
- Add the dissolved solution gradually while circulation/filtration is running.
- Typical shock dose: 5–10 g per 1,000 litres of pool water, adjusted based on chlorine demand and free chlorine test results.
- Test free chlorine and pH after treatment; ideal pool free chlorine range is generally 1–3 ppm.
- For industrial or drinking water use, dosing should follow site-specific water treatment protocols consult your process engineer.

When stored in a cool, dry place in unopened packaging, TCCA 90 Granular typically has a shelf life of 2–3 years.
Q: How much TCCA 90 Granular should I add to a pool?
A common shock dose is 5–10 g per 1,000 litres of water, but the exact amount depends on current chlorine demand — always confirm with a chlorine test before and after dosing.
Q: Can TCCA 90 Granular be added directly to pool water?
No. Granules should always be pre-dissolved in a separate container of water before being added to the pool, with filtration running.
Q: What packaging sizes are available for TCCA 90 Granular?
DS Water Technology supplies TCCA 90 Granular in 25 kg and 50 kg HDPE drums, with bulk and custom packaging available on request.
