EPAct certification
A.O. Smith Electrical Products is the first motor manufacturer certified by the U.S. Department of Energy as conforming to the Energy Policy Act of 1992 (EPAct). The company's general-purpose, integral horsepower motors meet or exceed the new government standards for energy efficiency. EPAct, which went into effect in October 1997, mandates that all general-purpose motors one to 200 horsepower that are produced for sale in the US meet nominal floor efficiency levels. A.O. Smith was the first manufacturer to apply for and receive the certification. Included in the certification are the company's E-Plus® and premium efficiency E-Plus® 3 motors, along with others.

Gas detection
MSA's Instrument Division has released the Ultima Plus Digital Network System, a high-performance gas detection system offering peer-to-peer digital communications for the Ultima® Gas Monitor family of products. The system is a high-speed modular communications network capable of monitoring and displaying data from multiple sensors via a two-wire link. It is an open system, allowing devices from various manufacturers to communicate and interface with MSA network components. It works with the Ultima monitor, display and relay modules. The system eliminates the need for a central controller or computer, freeing the user from traditional system capacity limitations and reducing costs.

Biological nutrient removal
The SymBio process from Enviroquip monitors NADH fluorescence to enable simultaneous nitrification and denitrification in one step and one basin. The process uses low oxygen levels and reduced aeration volume. The process has proven very suitable for rehabs that have avoided the cost of expansion. Some of the major benefits associated with the system include a smaller foot print due to one-step nitrogen removal, energy savings and alkalinity recovery. Originally from Denmark, the SymBio process monitors biological activity directly from the bacterial mass rather than looking at the free water phase parameters like DO, pH, and ORP. Changes in NADH fluorescence signal reflect changes in bacterial activity and hence in the oxygen demand. This information is used to control the air supply to match the demand while maintaining low dissolved oxygen.
