  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • 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 ...

  • Techno-economic evaluation of water pumping windmills in India

    An attempt to develop a simple framework for techno-economic evaluation of windmills for irrigation water pumping has been made. The amounts of water delivered by five somewhat different designs of windmill pumps at different locations have been estimated. The unit cost of water delivered and unit cost of useful energy delivered by the windmills have been estimated. The monetary benefits that ...

  • Multiphase 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 ...

  • 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 ...

  • Selecting a pump for sea water reverse osmosis

    Reverse osmosis (RO) desalination has become a significant process used in the purification of water. Selecting the correct pump is a significant step in a well designed and properly operating pumping system. Although the pump is a relatively small part of the overall cost of an RO system, expenses resulting from downtime and inefficiency can quickly diminish the productivity of the RO system and ...

  • Thermodynamic modelling of a water-to-water heat pump using propane as refrigerant

    The aim of this paper is to develop a thermodynamic model for a water-to-water heat pump using propane as refrigerant. This model is based on the thermodynamic principals and heat transfer fundamental laws. The performances of the heat pump have been looked at as function of the water temperatures at the entry of the evaporator and the condenser. The results show that the cooling and heating COP ...
