Take a closer look at a chemical magnet. You're looking at a crystal of Allied Chemical alum—aluminum sulfate—magnified 75 times. When dissolved and fed into a wastewater stream, alum "attracts" pollutants and settles them to the bottom of a clarifier where they can be easily removed. The result is more effective chemical treatment in America's municipal and industrial wastewater plants.

Allied Chemical has been a leading supplier of alum for many years.But we're more than a chemical supplier. Our busi­ness is providing solutions to water treat­ment problems. That's why we've more than doubled our research efforts and built a team of water treatment experts and field service technicians who can respond to our customers' needs.

Allied Chemical is looking beyond alum to new products and systems to pro­vide wastewater solutions. We're involved with the development and production of new synthetic polymers that extend the efficiency of traditional alum treatment. And our scientists are looking at new and better ways to remove hazardous trihalometh-anes from drinking water, and at improved methods of oil-water separation.

Take a closer look at Allied Chemical. We're more than a prime source for waste­water chemicals. We're an integrated chem­ical resource for clear water solutions. Call or write: Allied Chemical, P.O. Box 2064R, Morristown, NJ 07960. (201)455-4400.
