Frequently Asked Questions
What is the available chlorine content of SDIC 55% and why does it matter?
SDIC 55% contains 55% available chlorine, which determines its disinfection strength. A higher available chlorine content means greater bactericidal efficiency, allowing lower dosage to achieve effective disinfection results in water treatment, swimming pools and other applications.
Is sodium dichloroisocyanurate (SDIC 55%) safe for use in drinking water treatment?
Yes. SDIC 55% is widely approved for drinking water disinfection. When used at the recommended dosage, it effectively eliminates bacteria, viruses and algae without adverse effects on the human body, making it suitable for waterworks and rural drinking water systems.
What packaging options are available for SDIC 55% granules?
SDIC 55% granules are available in HDPE drums, fiber drums and plastic buckets in standard sizes of 1kg, 5kg, 10kg and up to 50kg. For bulk orders, jumbo bag packaging and custom solutions are also offered to meet different purchasing requirements.
How does SDIC 55% compare to TCCA 90% in terms of safety and application?
SDIC 55% is classified as Class 9 dangerous goods, which is a safer classification compared to TCCA 90% (Class 5.1 oxidizer). SDIC 55% has a milder chlorine odor and less irritation to skin and respiratory tract, making it more suitable for applications requiring regular human contact, such as food processing and civilian hygiene disinfection.
Can SDIC 55% be used in aquaculture and livestock farming?
Yes. SDIC 55% is commonly used in aquaculture for pond cleaning, water body disinfection and fish seed disinfection. In livestock and poultry farming, it is applied for disinfecting pens, utensils and egg storage areas to kill bacteria, viruses and fungi, improving survival rates and reducing disease transmission.
What granularity options are available for SDIC 55%, and how do I choose the right one?
SDIC 55% is available in two granularity ranges: 8–30 mesh (coarser granules) and 20–60 mesh (finer granules). Coarser granules are typically preferred for swimming pools and industrial water treatment due to slower dissolution, while finer granules dissolve faster and are suitable for agricultural spraying, food processing and household disinfection.
