Generating Chlorine Dioxide Gas: Chlorate vs. Chlorite

This paper evaluates the effectiveness of generating chlorine dioxide gas using Eka Chemical's method of sodium chlorate/hydrogen peroxide/sulfuric acid technology as it compares to the Rio Linda (Vulcan) chlorine gas/25 percent sodium chlorite system process at the El Paso Water Utilities' 40 mgd Canal (Umbenhauer/ Robertson) Water Plant in El Paso, Texas.

Deck: 

Is a new method of generating chlorine dioxide gas using sodium chlorate more effective than the typical sodium chlorite system?

Calcium Hypochlorite Chlorinating System Reduces Microbial Growth

ADM Milling Co./Nokomis Mill is a grain milling company that produces flour for regional bread manufacturers. Located in Minneapolis, ASM produces 10,000 cwt., or one million pounds of flour a day. Their use of chlorinated water results in the treatment of 1.2 to 3.5 gallons of water per minute.


ADM Milling relies on chlorinated water in the tempering process of grain milling production. In short, the tempering process cleans the wheat to rid it of dirt and debris, toughens the outer layer of the wheat kernal, and softens the inside - or the part ADM harvests and turns into flour.
