Innovacorp is a manufacturer, exporter and supplier of chlorine tablets for US water treatment and disinfection. The range covers TCCA 90 tablets for pools and cooling towers, and SDIC tablets for drinking water and emergency disinfection, used across commercial, municipal and industrial water systems in the United States.

Why Chlorine Tablet Selection Matters in the US

Water disinfection in the United States runs under a regulatory framework that shapes product selection more than most buyers expect. The Safe Drinking Water Act and EPA rules set treatment requirements for public water systems. NSF/ANSI 60 certification applies to drinking water treatment chemicals. A chlorine tablet that works in a swimming pool may not be approved for potable water use, and vice versa. This is where product selection and documentation matter more than a generic tablet listing.

Supply is another factor. The US market draws on both domestic and imported chlorine tablets, and buyers who understand the difference between TCCA and SDIC can match the product to the application instead of over-specifying or under-specifying. A pool operator in Arizona needs different chemistry than a municipal plant in Ohio, and a cooling tower in Texas needs different dosing than a well disinfection job in Michigan.

TCCA vs SDIC: Which Tablet for Which Application

The two main chlorine tablet chemistries behave differently, and US applications call for different choices:

• TCCA 90 (Trichloroisocyanuric Acid): around 90% available chlorine, slow-dissolving, acidic (1% solution pH 2.7–3.3). Best suited for outdoor swimming pools, industrial circulating water and applications needing long-lasting residual chlorine.
• SDIC (Sodium Dichloroisocyanurate): 56–62% available chlorine, fast-dissolving, near-neutral pH (5.5–7.0). Best suited for drinking water treatment, indoor pools and emergency disinfection where rapid action and pH stability matter.

US Regional Water and Application Profiles

Disinfection needs vary sharply by region and application:

• Sunbelt states (Arizona, Florida, Texas, Nevada): high UV exposure and long pool seasons. TCCA 90 is preferred because the cyanuric acid in TCCA stabilises chlorine against UV loss, reducing daily consumption.
• Midwest (Illinois, Ohio, Michigan): indoor pools and cooling towers with seasonal algae issues. SDIC is common for indoor pools where pH stability matters; TCCA for cooling tower intermittent dosing.
• Gulf Coast (Texas, Louisiana, Florida): high humidity and organic load. Higher chlorine demand from biological growth; dosing frequency set higher than inland plants.
• Northeast and Pacific Northwest: lower pool season but stringent discharge rules. Tablet feeders with controlled dosing preferred over granular shock dosing.

Where Our Chlorine Tablets Are Applied

• Swimming pools (residential and commercial): TCCA 90 tablets for long-lasting residual disinfection in outdoor pools, and SDIC for indoor pools and spa applications where pH stability matters.
• Cooling towers: TCCA tablets for algae and biofilm control in recirculating cooling water. Intermittent dosing is common, based on microbial load and blowdown schedule.
• Drinking water systems: SDIC tablets where NSF/ANSI 60 compliance is required. Used in small community systems, wells and point-of-entry treatment.
• Emergency water treatment: SDIC effervescent tablets for rapid disinfection of tanks, wells and stored water after flooding or supply disruption.
• Industrial process water: tablet dosing for microbial control in pipelines, storage tanks and CIP circuits.

Types We Manufacture, Export & Supply for US Plants

• TCCA 90 Tablets: 1g, 2g, 3g, 5g, 10g, 20g, 50g, 200g tablets for pools and industrial water.
• SDIC Tablets (NaDCC): 1g, 2g, 3.4g, 8.68g effervescent and non-effervescent tablets for drinking water and emergency use.
• TCCA Granules: for dosing systems where tablet form is not suitable.
• SDIC Granules: for bulk dosing in municipal and industrial water treatment.

Application and Dosage Guidance

Dosage depends on application, water volume and target chlorine residual. Indicative starting ranges:

• Swimming pools: 1 – 3 ppm free chlorine residual maintained with TCCA tablet dosing.
• Cooling towers: 0.5 – 2 ppm residual, dosed intermittently based on microbial load.
• Drinking water: 0.2 – 2 ppm residual, dosed according to local regulations and SDIC tablet size.
• Emergency water treatment: 1 tablet per specified volume (varies by tablet size and manufacturer instructions).
• Industrial process water: 0.5 – 2 ppm residual, dosed based on microbial load and system volume.

These are indicative only. Final dosage is set after water analysis and confirmed against local regulatory requirements.

Common Operating Issues and Fixes

• Slow tablet dissolution: often due to low flow through the feeder or cold water. Check feeder flow rate and water temperature; TCCA dissolves slower than SDIC by design.
• Chlorine residual dropping: can indicate high chlorine demand from organics or sunlight. Test cyanuric acid level (TCCA pools) and check for organic load.
• Feeder scaling: common with hard water and TCCA (acidic). Periodic acid washing of feeder and check for scale build-up.
• Tablet bridging in feeder: usually from moisture ingress or oversized tablets. Store tablets dry and match tablet size to feeder design.
• pH drift downward: TCCA is acidic; monitor pH and adjust alkalinity if pH drops below 7.2 in pools.

Packing

• 1 kg, 2 kg, 5 kg, 10 kg plastic jars
• 25 kg, 50 kg plastic drums
• 1000 kg jumbo bags (for granules)

Key Benefits for US Plant Operators

• TCCA 90 tablets provide long-lasting residual chlorine for pools and cooling towers.
• SDIC tablets dissolve rapidly for emergency and drinking water applications.
• Tablet form is easier to handle and dose than gaseous chlorine.
• Available in multiple tablet sizes for different dosing systems.
• Documentation available for NSF/ANSI 60 and EPA compliance review where applicable.
