What Is Granular Chlorine?
Granular chlorine is the general term for chlorine-based disinfectants produced in granular form. It is not a single chemical but a category that includes several distinct compounds, each with different active chlorine concentrations, solubility profiles, and applications. The granular form factor is preferred in industrial and commercial water treatment because it is easier to transport, store, and dose accurately than liquid chlorine or gas chlorine.
The main types of granular chlorine manufactured by Everglory Industrial include Calcium Hypochlorite, Trichloroisocyanuric Acid (TCCA), Sodium Dichloroisocyanurate (SDIC), BCDMH, and Chlorine Dioxide generating compounds. Each type has specific advantages depending on the application, water chemistry, and required disinfection profile.

Calcium Hypochlorite Granular
Calcium hypochlorite is the most common form of granular chlorine for water treatment. With 65%-70% available chlorine, it provides a strong, fast-acting disinfectant suitable for drinking water, swimming pools, and industrial processes. It dissolves relatively quickly without leaving cyanuric acid residue, making it ideal for applications where chlorine stabilizer levels need to be controlled.

Trichloroisocyanuric Acid (TCCA) Granular
TCCA contains the highest available chlorine content at 90%, making it the most concentrated chlorine disinfectant in granular form. Its cyanuric acid backbone provides UV stabilization, meaning the chlorine residual lasts longer in outdoor pools exposed to sunlight. TCCA granular dissolves slowly, providing continuous disinfection over extended periods. This makes it the preferred choice for swimming pool maintenance programs. View TCCA granular products →
Sodium Dichloroisocyanurate (SDIC) Granular
SDIC (also called Dichlor or Euchlorine) offers 56%-60% available chlorine with the fastest dissolution rate among stabilized chlorine compounds. It is commonly used for shock chlorination in pools and spas, where rapid chlorine residual increase is needed. SDIC is also widely used in hospital disinfection, food processing sanitation, and epidemic disease control due to its broad-spectrum antimicrobial activity. View SDIC granular products →
Granular Chlorine Sizing & Packaging
Standard mesh sizes for granular chlorine products:
- 8-30 mesh: Most common for calcium hypochlorite — balances dissolution rate with dust control
- 8-30 mesh: Used for TCCA granular — uniform particle distribution
- 20-40 mesh: Finer granules for applications requiring faster dissolution
- Custom sizes: Available upon request for specialized applications
Packaging options range from 1kg drums for retail distribution to 50kg drums for bulk industrial supply. We offer round drums, square drums, fiber drums, and customized packaging solutions. All packaging complies with international dangerous goods transport regulations.
How to Choose the Right Granular Chlorine
Selecting the appropriate granular chlorine depends on several factors:
- Application: Drinking water treatment typically uses calcium hypochlorite. Swimming pools use TCCA for regular maintenance and SDIC for shock treatment. Industrial cooling water often uses calcium hypochlorite or BCDMH.
- Dissolution rate needed: For continuous feed systems, slower-dissolving TCCA is preferred. For rapid dose adjustment, calcium hypochlorite or SDIC provide faster chlorine release.
- UV exposure: Outdoor applications benefit from stabilized chlorine (TCCA, SDIC) which contains cyanuric acid to protect chlorine from UV degradation.
- Calcium hardness sensitivity: In applications where calcium buildup is a concern (e.g., certain pool types), TCCA or SDIC avoid adding calcium to the water.
- Cost per available chlorine: TCCA 90% offers the highest chlorine content per kg, often making it the most economical choice on a cost-per-chlorine basis.
