Firstly Sodium Hypochlorite – 25l (12-15%) 25 . A 12% solution is widely used in waterworks for the chlorination of water. A 15% solution is more commonly used for disinfection of waste water in treatment plants.

Sodium hypochlorite is widely used in various applications. It is used on a large scale for water and surface purification, bleaching, odour removal, and water disinfection. Sodium hypochlorite is light yellow with a strong bleach odour. Sodium hypochlorite is a chemical that is produced through the mixing of caustic soda, liquid chlorine and water.

The anhydrous compound is unstable and may decompose explosively. Sodium Hypochlorite – 25l in solution exhibits broad-spectrum anti-microbial activity and is widely used in healthcare facilities in a variety of settings. It is usually diluted in water depending on its intended use. “Strong chlorine solution” is a 0.5% solution of hypochlorite (containing approximately 5000 ppm free chlorine) used for disinfecting areas contaminated with body fluids, including large blood spills.

Finally it may be made by diluting household bleach as appropriate (normally 1 part bleach to 9 parts water). Such solutions have been demonstrated to inactivate both C. difficile and HPV. “Weak chlorine solution” is a 0.05% solution of hypochlorite used for washing hands, but is normally prepared with calcium hypochlorite granules.
