Flood-proof submersible actuator helps plants operate in high-water events

Valves in today’s water treatment plants require dependable and precise positioning control. However, long life-span requirements and variables such as humidity and harsh weather can cause electric actuators to be unreliable or to fail prematurely. That’s why rugged, dependable actuators are needed for modulating and fixed position control of those valves, especially during harsh weather and its aftermath. 

Emerson recently introduced the EIM Aquanaught for those challenging conditions. The waterproof submersible electric actuator is designed to meet critical isolation demands on wastewater treatment plants during high water conditions.

“When floodwaters begin to overwhelm wastewater treatment facilities, it becomes critical for these plants to keep pace with the changing conditions and continue to operate for the sake of their communities,” says Shimona Verma, senior product marketing manager for actuation technologies at Emerson Automation Solutions.

The EIM Aquanaught can be submerged and still operate under 150 feet of dirty water for seven days, which is substantially deeper and longer than the company’s previous submersible technologies. It has a durable mechanical design with a waterproof enclosure and hermetically sealed connections that ensure uninterrupted plant operation during flooding conditions.

Ideal for gate or valve isolation applications found in wastewater, water, collections systems, hydropower, flood control, and desalination plants, the design allows these facilities to remain in control of their isolation needs from a safe remote location, even if the actuator becomes submerged for extended periods of time. Waterproof sensors provide additional protection by enabling early diagnostic and preventive maintenance during the flooding event.

According to the U.S. EPA, the country processes approximately 34 billion gallons of wastewater every day. During events like hurricanes Sandy, Irma and Harvey, billions of gallons of untreated sewer overflowed into impacted communities, posing significant health and environmental risks to the affected areas. With flooding an immediate threat to water systems in any heavy rain event, the need for more reliable actuation technologies becomes critical for these facilities.

“More facilities are looking to upgrade their infrastructure to ensure they aren’t outmatched by future floodwaters, and we believe that the EIM Aquanaught is a reliable component that will help their operations stay afloat,” Verma says. www.emerson.com/EIMAquanaught
