  • Fire Codes: A Foundation of Safety for a Rapidly Changing World

    Chief among these safety features is fire protection. There are myriad codes and regulations relating to fire safety in commercial buildings, from standards on portable fire extinguishers to the installation of stationary pumps for fire protection — the U.S.- based National Fire Protection Agency (NFPA) alone has more than 300 consensus codes that have been adopted in whole or in part ...

  • The Clog Blog

    Clogging and over pressuring are definitely problematic for Liquid Chromatography columns. Back in 2005 John Dolan’s sage advice to chromatographers to make an LC column last forever was simple, “Never open the box!” As John pointed out, this is not practical and I have to agree. But as an LC column manufacturer I have seen remarks from customers regarding clogging as though it ...

  • What Is Zero Liquid Discharge and How Does It Work?

    Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment. If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be ...

  • Low energy mixing to optimize anaerobic digestion at the Kitchener WWTP

    The existing Kitchener Wastewater Treatment Plant (WWTP) is a conventional secondary treatment facility, with a rated capacity of 122,745 mVd. The plant is comprised of two separate secondary treatment plants (Plant 1 and Plant 2) served by a common headworks facilities and primary clarifier facilities. Plant 1 was constructed in the early 1960s and Plant 2 was constructed in the mid-1970s. Both ...

  • Indestructible Pumps for Clean Water

    Sulzer pumps are used in the production of drinking water in many cities around the world. The special qualities that these pumps possess can be seen at the Zurich Municipal Water Utility. There, the operators have to cope with rising land and energy prices and a challenging topography. A small water flea plays a major role in Zurich. It swims around in a container of drinking water with some of ...

  • Upgrading Water Injection Pumps

    Water injection pumps that are used in oil exploration typically face extreme abrasion, chemical attack, and cavitation erosion in their daily operation. The injected water is frequently loaded with abrasive particles, such as quartz sand, which quickly erode conventional pump surfaces. Sulzer’s service teams offer solutions to increase the lifetime and the performance of water injection ...

  • Peristaltic pumps for moving filtration water

    The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents and is one of three plants operated by the city of Osnabrück in northern Germany. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant's capabilities. To deal with this situation, engineer Peter Sikora organized a team ...

  • Pumping water to decontaminate a karstic spring

    After being struck by lightning, an underground military fuel tank lost all its contents. After a few hours, petrol mixed with foam began to flow out of the nearby Forame spring, situated about 400 m away and at a height of 7.0 m lower than the bottom of the tank. The spring feeds the Giavera stream which, after about 1000 m enters the upper Veneto plain, flowing into the irrigation network. ...

  • Pumping Polyelectrolyte in waste water treatment

    The Challenge An industrial waste water treatment company required a cost effective solution to pumping polyelectrolyte. The plant engineers approached Verderflex distributor, Global Pumps Australia, for a solution to the following problems: Existing helical rotor pumps were expensive to run and maintain The replacement pump would have to be able to ...

  • Verderflex peristaltic pumps replaces mag drive pumps in water treatment

    Verderflex provided a cost effective solution to a Swiss airport that had been experiencing significant problems with their water softening treatment. The local water supply required treatment to prevent scaling in the pipework.  The Challenge The existing treatment system required a salt solution to be dosed from a storage tank close to the pumps ...

  • Hand-pumps as reservoirs for microbial contamination of well water

    The retention and release of total coliforms and Escherichia coli was investigated in hand-pumps removed from tubewells tapping a faecally contaminated aquifer in Matlab, Bangladesh, and from a new hand-pump deliberately spiked with E. coli. All hand-pumps were connected to reservoirs of sterile water and flushed. Faecal coliforms were observed in the discharge from all three of ...

Therefore this novel pump conception barely has ...

  • Pumps for energy-efficient water and wastewater treatment

    Multiphase pumps are unique products with outstanding features compared to conventional centrifugal pumps. The approach consists of using the pumps not only for transport of liquids but also for partial gas supply and as dynamic mixer for gas enrichment. Therefore this novel pump conception barely has something in common with a standard pump. Even the mode of ...

  • Performances of photovoltaic water pumping systems: a case study

    This paper presents a mathematical motor-pump model for photovoltaic (PV) applications which allow us to contribute in the studies of PV pumping sizing. The modelled motor-pump characteristic is flow rate-power (Q, P). The model is established for centrifugal pump (CP) coupled to DC motor. The non-linear relation between flow rate and solar power has been obtained experimentally in a first step ...
