Dow Corning Presents
Concentrated Look at Cost Effective Antifoams Boost production capacity. Reduce process contamination. Reduce environmental concerns. Do all that (and more) with DOW CORNING silicone antifoams. They're concentrated, so a little goes a long way, lasts a long time. In uses such as these: antifoam concentrate in the vessel makes the cleansers as easy to pour as water. Manufacturers of these cleaners now enjoy savings in labor costs and time.
No indigestion for waste-digesting bugs.
please. NoNostarch, cost either.
A maker of snack foods had a problem. Washing raw potatoes created a thick, gel-like starchy foam that attracted dirt, reduced production rates, and required constant clean-up. Organic antifoams failed—they clogged pipes. Dow Corning food grade antifoam zapped the foam. And made possible recovery of the starch for sale to a paper mill, which covers the cost of the antifoam.
How tofillwithout foaming at the mouth. Transferring cleaning agents from the mixing vessel to retail-size containers causes foaming. And it's timeconsuming to let the foam settle and then refill to make sure the container is full. Just one ounce of Dow Corning industrial

Organic process wastes are notorious foamers. When they're discharged to an aeration basin for digestion by microorganisms, the foam can cause wastes j> to go untreated and be discharged as pollutants. One %#. y quart of Dow Corning antifoam for every r million or so gallons of waste controls the foam. Organic antifoams would be gobbled up by the microorganisms. Not Dow Corning antifoam. The bugs leave it alone and chomp away at the harmful wastes.
Foam in extreme pH goes pfflft! A large petrochemical plant strips ammonia from wastewater and flares it off. Organic contaminants produce huge amounts of foam in the stripping column, cutting its ammonia removal efficiency. The plant evaluated
a number of antifoams and found one of the Dow Corning industrial antifoam concentrates most effective. It is continuously injected into the column at concentrations of 10 to 20 ppm. It gives long-lasting foam control even in these harsh conditions.
Antifoam makes a spectacle of itself. Here's how a full-service optical lab doubled its production. The slurry they used to polish lenses foamed up, degrading polishing and increasing lens breakage. A single drop of Dow Corning antifoam emulsion cut foam to virtually nothing. And without it, claims the lab owner, lens production would be cut in half.
