West Springfield, Massachusetts -- (March 1996)- EPR Inc. has announced that its patented Aerodynamic Module (ADM) is now being used in Church & Dwight's sodium bicarbonate process, specifically in their particle size classification system.

The ADM, which uses aerodynamic forces to separate and capture particulate generated during the manufacturing process, is more efficient, requires less space and uses less energy than the conventional system used by ARM & HAMMER, the trademark under which most of Church & Dwight's products are sold.

"The ADM offered a solution that was simple and cost effective to install," said Cathleen Doherty of EPR Inc. "The ADM has been incorporated into Church & Dwight's current system with minimal additional ductwork and has considerably decreased the dust loading to the bag house."

The ADM gas cleaning technology has no moving parts, replaceable filters or water treatment requirements, so maintenance costs can be cut to a minimum.

"Church & Dwight's goal was to increase the system's capacity by 50 percent," said Jim Dynes of Church & Dwight. "The ADM allows us to exceed these goals and remain cost effective. In addition, a big draw to the ADM was its minimal space requirements, which enabled us to execute the improvements necessary and make only minor changes to the system."

EPR Inc. is a product recovery and air pollution control company with a patented particulate collection, separation and reprocessing technology. The ADM, already in commercial use in Russia, has applications in the cereal, cement, paper, chemical, mineral and other industries.

Church & Dwight Company, Inc., in Princeton, New Jersey, is the world's leading producer of sodium bicarbonate, a natural product that cleans, deodorizes, leavens and buffers.
