GENERAL DESIGN NOTES
The storage area should not be exposed to direct sunlight or ultraviolet light. Exposure to sunlight or ultra-violet light will reduce product strength. Heat Trace and Insulate if necc to prevent crystalization which occur even at ambient temperatures 32F(30% concentration) to 70F(40% concentration). Include PolyLevel Temperature and level probe to know temperature and prevent crystalization.
Strictly meet or oversize vent to prevent chlorine dioxide gas from forming.
Wetted parts should be titanium.
REGULATIONS
The EPA has set a maximum contaminant level of 1 milligram of chlorite per liter (1 mg/L) in drinking water
WARNINGS
- Easily ignites by friction if combined with a reducing agent like powdered sugar, sulphur or red phosphorus
- Do not use absorbant type fiberglass insulation on tanks
- Will turn shock-sensitive if contaminated with organic matter.
- Do not contaminate sodium chlorite with incompatible materials such as dirt, organic matter, oxidizers, reducing agents, chemicals, soap products, solvents, acids, paint products, or combustible materials. Do not store or transport sodium chlorite with incompatible materials. Contamination may start a chemical reaction with generation of heat and emission of chlorine dioxide
- shoud not be stored next to reducing agents, acids, ammonium compounds, phosphorus, sulfur or sodium dithionate
- Do not allow solution to evaporate to dryness; this product becomes a fire or explosion hazard if allowed to dry and can ignite in contact with combustible materials.
OPTIONS
APPLICATIONS
The main application of sodium chlorite is the generation of chlorine dioxide for bleaching and stripping of textiles, pulp, and paper.
It is also used for disinfection of municipal water treatment plants after conversion to chlorine dioxide.An advantage in this application, as compared to the more commonly used chlorine, is that trihalomethanes (not allowed back into water by regulations) are not produced from organic contaminants as they are with Chlorine. Chlorine dioxide generated from sodium chlorite is approved by FDA under some conditions for disinfecting water used to wash fruits, vegetables, and poultry.
Sodium chlorite, in combination with zinc chloride, also finds application as a component in therapeutic rinses, mouthwashes, toothpastes and gels, mouth sprays, as preservative in eye drops, and in contact lens cleaning solution under the trade name Purite. Under the brand name Oxine it is used for sanitizing air ducts and HVAC systems.
