Stop Using the Wrong Disinfectant! How to Choose Between TCCA and SDIC Like a Pro ？

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.
