Safety upgrades imposed by the United States Nuclear Regulatory Commission (NRC) several years ago required nuclear power plants across the United States to review operations and enhance safety protocols. As a part of this process, a nuclear power plant located in the northeast of the U.S. sought an emergency back-up solution to inject cooling water into the plant reactor in the event that all other means of cooling failed.

Alliance Resource Partners, L.P. faced a two-pronged water challenge at one of its many underground mines. At the South Mine of the company’s Gibson County Coal in Indiana, solid-laden water needed to be pumped out of the mine, and a dewatering system needed to be installed in an area with limited space. Multiple pumps had to fit into a mine void less than eight feet high with a narrow, 20-foot entry span.

One customer, operating a hard rock nickel mine in Ontario, needed an efficient and reliable solution to transport its mine slime from an underground sump back to the surface while ensuring continuity in production and minimizing downtime.

A customer in Perú needed to drain water as its large open-pit mine operation reached as deep as 1,200 ft (365 m) below the surface. The discovery of more copper in the mine, and an expected excess of water during rainy summer months also prompted the company to act. They sought a remote solution for monitoring and controlling their pumping system, particularly as routing electrical power became more difficult the deeper they dug....

Operators of one of the largest coal fired power plants in the US based in Michigan, were looking for an efficient, robust and reliable pumping solution to move sludge water from each of the plant’s four sumps.

Xylem Rental Solutions helped a North Carolina community restore water service quickly during the COVID-19 outbreak with a temporary replacement, using a Flygt submersible pump, after a permanent pump failed.

Flygt Concertor was trialed at Heathrow Airport to solve chronic clogging and delivered clog-free pumping while cutting energy use by 53%.

Xylem was tasked with designing a seep collection system to collect water from a low volume seep through the wall of a decommissioned fly ash pond. The sump was located in an active river floodplain that flooded with as little as 1-2 inches of rain, so the customer needed an automatic shutdown when the river covered the sump.

The city needed to discharge sludge at two different rates–one rate for sludge returning to the headworks RAS and another rate for sending material to the sludge box. The system is designed to speed up dewatering biosolids as a replacement to the existing sand drying beds.

The 4220 mixer comes in 1.5-, 2-, 3-, and 4-horsepower models. A four-horsepower mixer can operate at any lower power level and perform with the same high efficiency as a lower power model.
