Chlorine Tablets
Chlorine Tablets are solid, compressed forms of chlorine-releasing compounds, typically composed of stabilized trichloroisocyanuric acid (TCCA) or sodium dichloroisocyanurate (SDIC). These tablets are used primarily for water disinfection and sanitation due to their controlled and sustained release of chlorine. They appear as white to off-white, hard tablets with a mild chlorine odor. Chlorine Tablets are widely used in swimming pools, drinking water treatment, wastewater treatment, and industrial sanitization processes. Their slow dissolution ensures prolonged antimicrobial activity, providing effective control against bacteria, viruses, algae, and other pathogens.

Activated Carbon (Charcoal)
Activated carbon is a highly porous, adsorptive material processed to have an exceptionally large surface area (typically 500-1500 m²/g) through thermal or chemical activation of carbon-rich source materials. This versatile adsorbent exists in powdered (PAC), granular (GAC), pelletized, and extruded forms, with pore structures specifically engineered for different applications ranging from water purification to gas treatment. Its extended surface area and complex pore network (micropores <2nm, mesopores 2-50nm, macropores >50nm) enable superior physical adsorption of contaminants through van der Waals forces, as well as chemical interactions with surface functional groups.
Anti Foam
Anti foams are chemical additives designed to reduce or prevent the formation of foam in industrial processes, manufacturing, and various formulations. Foam can interfere with operations such as mixing, filling, pumping, and heat transfer, leading to reduced efficiency or defects in products. Anti foams work by destabilizing foam bubbles, causing them to coalesce and collapse rapidly. They are widely used in industries including food and beverage, pharmaceuticals, wastewater treatment, paints and coatings, and chemical manufacturing. Different types of anti foams include silicone-based, mineral oil-based, and organic polymer-based formulations, chosen according to the specific application and process conditions.
Benzyl Konium Chloride
Benzyl Konium Chloride (BAC) 50% is a quaternary ammonium compound with potent antimicrobial and disinfectant properties.
