Frequently Asked Questions
What is sodium dichloroisocyanurate (SDIC) 55% and how does it differ from SDIC 60%?
SDIC 55% contains 55% available chlorine and is in granular form with 10–14% moisture content, making it a dihydrate variant. It offers slightly milder chlorine odor and less irritation compared to anhydrous SDIC 60%, while still delivering highly effective disinfection across a wide range of applications.
What is the correct dosage for using SDIC 55% in swimming pool disinfection?
The typical dosage for swimming pool disinfection is approximately 1–3 ppm of available chlorine in the pool water. The exact amount depends on pool volume, bather load, and water conditions. Always test the water before and after application to maintain safe and effective chlorine levels.
Is SDIC 55% safe for use in drinking water treatment?
Yes, SDIC 55% is widely used in drinking water treatment and rural water supply systems. When used at the correct dosage, it effectively kills bacteria, viruses, and algae without adverse effects on human health. It is important to follow local regulatory guidelines and dosage recommendations for potable water applications.
How should SDIC 55% granules be stored safely?
SDIC 55% should be stored in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, and incompatible materials such as acids, ammonia, and flammable substances. Keep containers tightly sealed to prevent moisture absorption. Store away from food, feed, and children.
What packaging options are available for SDIC 55% and can custom packaging be arranged?
SDIC 55% is available in standard packaging including HDPE drums, fiber drums, and plastic buckets in sizes ranging from 1kg to 50kg. For large-volume orders, jumbo bag packaging is available.
