Faced with rising operating costs due to increasing energy and chemical prices as well as stricter effluent permit limits, many operators and engineers are turning to sensors and automation as a means to enhance treatment performance and reduce operating costs while limited capital expenses. In order to overcome these challenges, an advanced process control solution was implemented in an aerobic digester in Green Lake, Wisconsin.
A large percentage of the flow meters purchased for municipal water plants are replacements for older meters in existing facilities or distribution systems. It’s a common practice to replace aging meters with the same technology, often from the same manufacturer.
When the polar bears at the Brookfield Zoo were introduced to their new habitats at the Great Bear Wilderness, they had no idea how much more fulfilling their life would become.
If modernizations in wastewater treatment plants are due, as a rule the permanently reducing limit values of ammonium, nitrate and phosphate are pushing the investment decisions.
A state-of-the-art 695-MW power generation facility was recently installed in the Northeastern U.S. to serve the country’s highest demand market. Its innovative power generation technologies, emissions control systems and process efficiencies make it one of the cleanest, most efficient and technologically advanced supercritical pulverized coal (SPC) power plants in the U.S.
Metro Waste Reclamation District is one of the largest wastewater treatment plants between the Mississippi River and the west coast. Treated water is discharged into the South Platte River, and contributes 90% of the river’s annual flow at the point of discharge.
In recent years, the robust growth of residential and commercial development in the Outer Banks of North Carolina has put a strain on many of the wastewater services in the area. The Monteray Shores WWTP in Corolla, at the northern end of the Outer Banks, was no exception.
For many small and medium communities, centralized or conventional sewer options are technically complicated and/or are often the expensive choice for managing wastewater treatment. As the demand for water reaches critical levels for most areas around the world, decentralized treatment systems are becoming increasingly popular by returning treated water back to the local environment.
The Kittansett Golf Club in Marion, Massachusetts is rated one of America’s 100 Greatest Golf Courses by Golf Digest Magazine.
After two years operation the plant reports that RoS2S Disk Thickener is consistently producing a 5.5% DS average with an ~0.6% DS average feed at a steady flow of 107 gpm (60 gpm activated, 7 gpm trickling, 40 gpm service water) running 24 hours a day.
