Sodium hypochlorite

Clear, pale yellow liquid with chlorine odor.

Sodium hypochlorite is a clear, pale yellow liquid characterized by a distinct chlorine odor and strong oxidizing properties. It is typically available in aqueous solutions ranging from 5% to 20% concentration. This compound is extensively used as a bleaching agent in industries such as textile manufacturing and paper production, where it helps whiten and brighten fabrics and paper products. Furthermore, sodium hypochlorite plays a vital role in water treatment, ensuring the maintenance of high-quality water standards.


Water Treatment

Sodium hypochlorite is widely utilized in water treatment processes as a disinfectant and oxidizing agent. It is highly effective in purifying water sources, targeting and neutralizing various contaminants to ensure water safety. In water treatment systems, sodium hypochlorite is carefully added in controlled amounts to help maintain water quality standards and support the prevention of waterborne diseases. Beyond its role in purification, it serves as a bleaching agent that aids in the removal of color and odor from water, enhancing its aesthetic and sensory qualities. The application of sodium hypochlorite in water treatment requires precise monitoring and regulation to avoid excessive dosing and mitigate potential environmental impacts.

Pulp & Paper

Sodium hypochlorite plays a crucial role in the pulp and paper industry, particularly in the bleaching process of wood pulp, the fundamental raw material for manufacturing paper products. During the bleaching stage, sodium hypochlorite is introduced to the wood pulp to eliminate color, thereby enhancing the paper’s brightness and overall quality. Its effectiveness as a bleaching agent allows it to be used alongside other chemicals to fine-tune the brightness and whiteness of paper to meet specific standards. The implementation of sodium hypochlorite in the pulp and paper industry necessitates meticulous monitoring and management to minimize the environmental impact, ensuring the process is both efficient and environmentally responsible.
