TCCA 90% Chlorine Tablets – 50 kg Drum | UV Water Systems Oman

Trichloroisocyanuric acid (TCCA) at 90% available chlorine is one of the most concentrated and stable solid chlorine disinfectants available. Unlike sodium hypochlorite liquid, which degrades rapidly in Oman’s heat, TCCA tablets remain stable for months at ambient storage temperatures and release chlorine slowly when dissolved in water — making them the preferred disinfectant for swimming pools, storage tanks, and large water systems across the Sultanate. UV Water Systems supplies TCCA 90% tablets in 50 kg drums to residential pool owners, hotels, hospitals, schools, and industrial facilities throughout Muscat and Oman.

How TCCA Chlorine Tablets Work

TCCA (C₃Cl₃N₃O₃) hydrolyses in water to release hypochlorous acid (HOCl), the primary disinfecting species, and cyanuric acid, which acts as a UV stabiliser in outdoor pools. The slow-dissolving tablet form allows continuous chlorine release over 24–72 hours depending on tablet size and water temperature, maintaining residual disinfection without manual dosing every few hours. For storage tank shock disinfection, tablets are dissolved at higher concentration in a batch dose. TCCA is effective against bacteria, algae, viruses, and Cryptosporidium at appropriate contact times and concentrations.

Key Features and Benefits

90% available chlorine: The highest concentration available in solid tablet form — a small quantity treats a large volume of water, reducing storage and transport requirements compared to liquid bleach.
Heat-stable in Oman’s climate: TCCA retains available chlorine at storage temperatures up to 50°C, unlike sodium hypochlorite which loses strength within weeks in Oman’s summer heat.
Slow-dissolving release: Tablet form releases chlorine gradually over hours, maintaining a steady residual in pools and storage tanks without concentration spikes that can irritate skin or eyes.
UV-stabilised for outdoor pools: The cyanuric acid produced during hydrolysis stabilises chlorine against UV photodecomposition — up to 75% of chlorine can be lost in one hour of direct Oman sunlight without cyanuric acid stabilisation.
Easy to handle and store: Solid drum format eliminates the spill and corrosion risks associated with bulk liquid chlorine — safer for facilities without dedicated chemical storage rooms.

Frequently Asked Questions

What is the correct dose for pool disinfection in Oman? For ongoing maintenance, maintain free chlorine at 1–3 mg/L. In Oman’s warm outdoor pools, higher circulation and UV load means faster chlorine consumption — check residual daily and dose accordingly. UV Water Systems can design a complete pool chemical programme for your facility.

Can TCCA tablets be used in drinking water tanks? TCCA is approved for potable water disinfection at prescribed doses. For storage tank shock chlorination, UV Water Systems recommends a dose producing 2–5 mg/L free chlorine with a 30-minute contact time before use. Always confirm suitability with your local health authority in Oman.
