The heart of the heating system features a set of “In-line” centrifugal pumps complete with Hydrovar® frequency converter model FCSH4 150-250/150 – FCS4H 125-200/55; these distribute water to 8 heating subsystems specific to the various buildings in the complex. Each subsystem features a series of multi-speed circulators which independently satisfy the demand of each single building.

The James River Treatment Plant is one of nine major treatment plants operated by the Hampton Roads Sanitation District (HRSD), a political subdivision of the Commonwealth of Virginia. Located in Newport News, Virginia, USA, the James River Treatment Plant is committed to protecting the environment and enhancing neighboring communities through a variety of wastewater treatment improvements.

Water is the lifeblood of community and industry in the picturesque seacoast towns of Kennebunk, Kennebunkport and Wells, Maine ... where tourism, farming, and commercial fishing help drive the local economy. That’s why, when two prevalent perfluoroalkyl substances (PFAS) — perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) — were detected...

When you’re the first manufacturing plant in the world to meet a rigorous international standard that rates how environmentally friendly you are, and when you’re required by law to limit groundwater use, chances are you’re going to choose an environmentally friendly, water-conserving purification system.

Howard County, Maryland, has taken a leading role in restoring the Chesapeake Bay ecosystem through a $92 million upgrade to its wastewater treatment infrastructure. Central to this effort is the installation of Xylem’s Leopold elimi-NITE® 2.0 denitrification system, which significantly reduces nitrogen and phosphorus levels in effluent discharge. Combined with advanced UV disinfection and mixing technologies, the system's daily reductions include 37,000 pounds of suspended solids, helping to reverse decades of nutrient pollution and protect aquatic life in the Bay.

The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured-concrete underdrains, which were no longer efficient. Prior to the filter rehabilitation, the utility’s backwash procedure consisted of a hydraulic-only backwash where the high-rate wash cycle lasted up to 20 minutes. Backwashing each dual cell filter used 150,000 to 200,000 gallons of water. The filters then operated up to an hour in rewash or filter-to-waste operation to reach the desired output of <0.09 Nephelometric Turbidity Unit (NTU).

Xylem’s Flygt Concertor, with integrated intelligence that uses sensor monitoring, self-optimising technology and adaptive hydraulics, was the perfect smart, energy-efficient processing method.

A southern mining company was developing salt dome gas storage facilities that use water to mine salt from the domes shaping them so they can be used to store natural gas inside under high pressures. The raw water used for the mining process contained high levels of iron (5-8 ppm) resulting in equipment fouling and high maintenance costs.

Increased discharge surcharges and newly imposed limits on wastewater strength prompted Oland Brewery to rethink its treatment strategy. The company wanted to be environmentally responsible, so it investigated on-site wastewater treatment options. Since the brewery is located in close proximity to neighboring buildings, space limitations were very influential in the brewery's technology selection.

AB Mauri was constructing a large, state-of-the-art yeast manufacturing plant in Veracruz, Mexico. The project included the need for a unique wastewater treatment facility. Sugarcane molasses used as the fermentation growth substrate for the yeast during production results in wastewater containing high concentrations of organic matter.
