TCCA and SDIC are both stable chlorine disinfectants, but they have significant differences in key characteristics. Simply put, TCCA is best for long-lasting efficiency, while SDIC is ideal for rapid action and routine dosing.
To help you understand their differences more intuitively,pls check the following information:
| Comparison Dimension | TCCA | SDIC |
| Available Chlorine Content | Very high, 90% | Medium, 55% - 60% |
| Dissolution Rate | Slow, dissolves slowly and releases chlorine continuously | Very fast, dissolves rapidly and increases residual chlorine quickly |
| Aqueous Solution pH | Strongly acidic (pH 2.6 - 3.2), significantly lowers water pH | Nearly neutral (pH 6.0 - 7.0), minimal impact on water pH |
| Skin/Eye Irritation | Releases a strong chlorine odor | Relatively mild, less irritating |
Main Application Scenarios | Long-term disinfection: Such as daily swimming pool maintenance, industrial circulating water, hospital sewage, etc., | Rapid disinfection: Such as food processing equipment, tableware, emergency drinking water treatment, surface spraying, etc., suitable for situations requiring quick results. |
How to Choose Based on Your Needs?
You can refer to the guide below to make a decision based on your specific requirements:
If you need a long-lasting, economical solution: Choose TCCA. Its high chlorine content requires smaller doses, making it ideal for daily pool maintenance and industrial water treatment.
If you seek quick results and ease of operation: Choose SDIC. SDIC dissolves fast for quick disinfection. Its neutral pH won't alter water balance, and it's gentle on skin and equipment. Ideal for food factories, tableware, and general sanitation.
