Sodium Dichloroisocyanurate, commonly known as SDIC (CAS 2893‑78‑9), is a professional broad-spectrum chlorine disinfectant widely recognized in global water treatment and environmental sanitation industries. Produced through advanced purification and crystallization technology, our export-standard SDIC maintains a high available chlorine concentration of 56%-60%, with strictly controlled moisture content below 0.5% and mild pH value between 5.5 and 7.0, achieving efficient disinfection while ensuring water body safety and stability. The product provides two practical forms: fine powder of 80-200 mesh and solid tablets of 8-30mm, adapting to diverse dosing methods and on-site operation requirements of different scenarios.

The core advantage of SDIC lies in its stable chlorine release and long-duration bactericidal capability. As a high-efficiency oxidative disinfectant, it can thoroughly kill Escherichia coli, staphylococcus, various algae, fungi and harmful viruses in water bodies, solving common problems such as water turbidity, algae breeding and bacterial exceeding standard. Its slow-release formula avoids rapid chlorine loss, greatly extending the water purification cycle and reducing frequent dosing frequency, which significantly saves operational costs for users. With mild and non-irritating water quality after dissolution, it meets the safety standards of drinking water and aquaculture water, no secondary pollution, safe and reliable.

SDIC has extremely wide application coverage, covering civil and industrial water treatment fields. It is the preferred disinfection material for swimming pool recreational water to keep water clean and hygienic; it is widely used for sterilization and algae removal of industrial circulating water to prevent pipeline blockage and equipment corrosion; it is commonly adopted for aquaculture water purification to optimize breeding environment and improve survival rate; it also serves as core disinfection agent for drinking water pretreatment and daily water quality maintenance. Our factory implements full-process quality inspection, ensuring stable chlorine content and zero batch difference. With sufficient inventory and mature global supply chain, we provide stable bulk supply and competitive pricing solutions for global water treatment companies, aquaculture manufacturers and industrial enterprises.
