Types of Bulk Chlorine
Liquid Chlorine
Liquid chlorine, typically in concentrations of 12.5% to 15%, is one of the most commonly used forms of bulk chlorine. It provides rapid disinfection and is easy to transport, making it ideal for commercial pools and municipal water treatment facilities. It can be used directly or through automatic chemical controllers for hassle-free application.
Sodium Hypochlorite
Sodium hypochlorite is a liquid chlorine solution that is effective for multiple applications, including swimming pools, power washing, and commercial cleaning. With no mixing required, it is user-friendly and prevents the build-up of scale or cyanuric acid, making it a preferred choice for pool operators. BulkChlorine.com and other suppliers offer sodium hypochlorite in 55-gallon drums and full pallets.
Calcium Hypochlorite
Calcium hypochlorite is a solid form of chlorine that is often used for pool shock treatment. With a higher concentration than liquid forms, it provides a longer shelf life and is effective in killing bacteria and algae. It is available in 50-pound bags and is suitable for residential and commercial applications.
Chlorine Tablets
Chlorine tablets are a convenient option for residential pool maintenance. They come in 1-inch tablet sizes and are easy to use in floaters or skimmers. Though they are less concentrated than liquid forms, they provide a slow-release option for steady chlorine levels in pools.
Chlorine Gas
Chlorine gas is primarily used in large-scale water treatment facilities for its high effectiveness as a disinfectant. It is delivered in cylinders or ton containers and requires specialized equipment for safe handling. This form is not typically used by residential customers due to safety concerns.
Applications of Bulk Chlorine
Pool Sanitation
Bulk chlorine, particularly in the form of liquid chlorine and sodium hypochlorite, is widely used for pool sanitation. The recommended dosage is typically 1 gallon per 10,000 gallons of water to achieve a concentration of 5 ppm. Regular monitoring of chlorine levels is crucial to maintaining a safe swimming environment.
Water Treatment
Municipal water treatment plants use bulk chlorine to disinfect drinking water. Chlorine is added to kill pathogens and ensure safe water for consumption. The dosage varies based on the water quality and the specific treatment process.
Cleaning and Disinfection
Sodium hypochlorite is commonly used in commercial cleaning applications. It is effective in disinfecting surfaces, equipment, and tools in industries such as food processing, healthcare, and hospitality. Its ease of use and effectiveness make it a valuable asset in maintaining hygiene standards.
Industrial Applications
Chlorine is also utilized in various industrial applications, including bleaching and chemical manufacturing. Companies like Hill Brothers Chemical Company and ACR Products, Inc. provide bulk chlorine for these specialized uses, ensuring quality and compliance with safety regulations.
