TCCA(Trichloroisocyanuric acid)
Trichloroisocyanuric Acid (TCCA) is a high-chlorine solid disinfectant with strong bactericidal effect. It releases hypochlorous acid gradually in water, providing efficient disinfection. With good stability and uniform solubility, it has low corrosion to equipment and is suitable for swimming pools, drinking water, industrial circulation water, wastewater treatment, and public sanitation.
Sodium hypochlorite - Applications and properties
Sodium hypochlorite (NaClO) is an inorganic compound known for its strong oxidizing properties. Commercially available as a pale yellow liquid with a concentration of around 5%, it is a common chlorine-based bleach and disinfectant used in both households and industry. It effectively kills bacteria, fungi, and viruses and is widely used for environmental cleaning, water treatment, and surface disinfection.
SDIC（Sodium Dichloroisocyanurate）
Sodium Dichloroisocyanurate (SDIC) is a chlorine-based disinfectant with high efficiency, stability, and easy handling. It is widely used for disinfection of drinking water, municipal water plants, swimming pools, industrial circulating water, aquaculture, and public sanitation. Additionally, it is applied in textile bleaching, paper making, and oilfield operations, showing broad market potential.
Calcium hypochlorite is a white granular or powdery inorganic highly oxidizing compound, commonly known as bleaching powder, renowned for its high available chlorine content (usually 60%-75%) and excellent bactericidal and bleaching abilities. It decomposes in water to form hypochlorous acid. Physical properties: White solid with a strong chlorine odor, soluble in water. It is mainly used for bleaching cotton and linen textiles, chemical fibers, pulp, and starch, as well as for disinfection and sterilization of drinking water and swimming pool water.
Aluminum sulfate is a white orthorhombic crystalline powder, readily soluble in water, with an acidic aqueous solution. It is primarily used as a high-efficiency industrial water purification flocculant and a sizing and precipitating agent in the paper industry. It forms precipitates by adsorbing suspended solids in water and is widely used in drinking water purification and wastewater treatment. It is also used in papermaking, fire-fighting foam, pharmaceutical astringents, and agricultural soil improvement.
Activated carbon is a highly efficient hydrophobic adsorbent, commonly used in air purification, wastewater treatment, decolorization and deodorization, and medical detoxification. It possesses a highly developed microporous structure and a large specific surface area, and is typically made from coconut shells, coal, and wood. It is renewable and exhibits physical/chemical adsorption properties for a variety of substances.
