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.

Automated Chlorination System Helps Chicken Processing Plant Meet U.S.D.A. Sanitation Guidelines

A California-based chicken processing plant needed an accurate, reliable method of maintaining high chlorine residuals in their sanitizing and cooling water tanks, known in the industry as "red water." This name comes from the content of blood and guts in the water. Although to the naked eye the water looks relatively free of these gory contents, it represented a chlorination control nightmare to the plant operators.


The tanks are about 4 ft. X 10 ft. X 40 ft. and contain approximately 100,000 gallons of chilled, chlorinated water at around 33°F.

Media is a Big Thing ... But Not the Only Thing

Shower filter dechlorination requires its own unique design approach to meet various health requirements.In less than 10 years, shower filters have grown from a non-industry to a significant niche market. Consumers, at first only concerned with the quality of their drinking water, are now more aware of the importance of removing chlorine, one of nature's most toxic elements, from their shower water, too.

Ozone for Water Treatment Gains Acceptance

Dealers of water enhancement products are increasing ozone sales rapidly, while finding sales of chemical-oriented products are less attractive to their clients. The advantages of ozonated water are becoming better understood and easier to sell. As consumers demand a better water supply, the use of chemicals will continue to diminish while the use of ozone increases.
