Key Features

Calcium Hypochlorite 65% Min is a powerful chlorine‑based disinfectant and oxidizing agent widely used for water sanitation and purification. It offers a high available chlorine content — at least 65% — making it significantly stronger and more effective in killing bacteria, viruses, algae, fungi, and other pathogens compared to low‑strength chlorine sources. Its solid granular or powder form dissolves readily in water to release hypochlorous acid, a potent sanitizing species that ensures rapid disinfection and ongoing protection in treated water.

Chemical Composition & Properties

The chemical formula of Calcium Hypochlorite is Ca(ClO)₂, and products with 65% available chlorine typically appear as white or off‑white granules or powder. Calcium hypochlorite is a strong oxidizer that reacts with water to form hypochlorous acid and calcium hydroxide. It is relatively stable under dry storage and dissolves in both warm and cold water, producing disinfectant solutions that are strongly alkaline. This compound has a strong chlorine odor and can be stored for long periods with minimal loss of potency when kept dry and cool.

Product Description

Calcium Hypochlorite 65% Min serves as a versatile disinfectant chemical used in a wide range of sanitation and water treatment applications. When dissolved, it releases active chlorine species that penetrate microbial cell walls, disrupt essential metabolic processes, and oxidize organic contaminants, leading to effective sanitization. Its high chlorine content means that relatively small dosages can achieve high levels of microbial control. This makes it an efficient choice for demanding applications where reliable disinfection is critical.

Applications in Water Treatment

Calcium Hypochlorite 65% Min is widely used for drinking water disinfection, swimming pool sanitation, and wastewater treatment. In municipal or emergency drinking water treatment, it kills pathogens to ensure water safety. For swimming pools and spas, it controls algae, bacteria, and organic loads to maintain hygienic water quality. It also serves in industrial water systems — such as cooling towers and process water — for biofilm control and odor prevention. Additionally, it is used in aquaculture, agriculture, and various sanitation scenarios requiring high microbial control.

Mechanism of Action

The disinfecting action of Calcium Hypochlorite 65% Min is based on the release of hypochlorous acid (HOCl) when it dissolves in water. Hypochlorous acid is a potent oxidizing agent that destroys microorganisms by disrupting cell membranes, denaturing proteins, and interfering with essential metabolic functions. This oxidation process also breaks down organic impurities and prevents microbial regrowth by maintaining a residual chlorine level in the treated water.

Usage & Dosing Guidelines

Proper dosing of Calcium Hypochlorite 65% Min depends on water volume, initial water quality, and treatment objectives. For drinking water and pool sanitation, dosing is adjusted to achieve recommended free chlorine residuals. Typical pool maintenance levels are maintained between recommended ppm ranges, while shock treatments use higher concentrations to rapidly restore water quality after heavy use or contamination. It is commonly advised to pre‑dissolve the calcium hypochlorite in a separate container before adding to the main water body to ensure even distribution and effective dissolution.

Benefits

Products with 65% minimum available chlorine offer high disinfection potency, rapid microbial kill, and broad‑spectrum action against bacteria, viruses, and algae. Their high chlorine content means smaller quantities are required compared to lower‑strength chlorine sources. Calcium hypochlorite is relatively stable in dry form — maintaining effective strength over time — and provides ongoing residual protection in treated water. These benefits make it a cost‑effective solution for large‑scale and high‑demand sanitation needs.

Safety Considerations

Handling Calcium Hypochlorite 65% Min requires appropriate personal protective equipment, such as gloves, eye protection, and masks, as it can cause irritation on contact and has a strong chlorine odor. It should never be mixed with acids, reducing agents, or incompatible chemicals, as such reactions can release toxic chlorine gas or lead to hazardous conditions. Adequate ventilation and careful handling minimize the risk of dust inhalation and chemical exposure.

Storage Instructions

Store Calcium Hypochlorite 65% Min in a cool, dry, and well‑ventilated area, protected from moisture, heat, and sunlight. Keep containers tightly sealed and separate from organic materials, acids, and reducing agents to prevent degradation and dangerous reactions. Regularly inspect storage conditions and packaging integrity to maintain long‑term effectiveness and safety. Proper storage preserves available chlorine content and ensures reliable disinfection performance when used.
