  • Hand-pump subsurface arsenic removal: the effect of groundwater conditions and intermittent operation

    Hand-pump subsurface arsenic removal (SAR) has been investigated in rural Bangladesh with different groundwater conditions and intermittent operation modes. Multiple injection-abstraction cycles were performed after injection of 1 m3 of aerated water. From these experiments it can be concluded that hand-pump SAR, in the traditional injection-abstraction design, does not provide drinking water ...

  • Development of Operation Navigation System

    ABSTRACTBureau of Tokyo Sewerage has 13 wastewater treatment plants and 82 pumping stations. In order to manage these facilities efficiently, collective operation in each treatment area is being promoted by making use of remote-control system. Promotion of remote control system leads to concentration of facilities monitored or controlled from the master facility, and, therefore, increases tasks ...

  • Operation of a full-scale pumped flow biofilm reactor (PFBR) under two aeration regimes

    A novel technology suitable for centralised and decentralised wastewater treatment has been developed, extensively tested at laboratory-scale, and trialled at a number of sites for populations ranging from 15 to 400 population equivalents (PE). The two-reactor-tank pumped flow biofilm reactor (PFBR) is characterised by: (i) its simple construction; (ii) its ease of operation and maintenance; ...

  • Safe, Effective Pumping: In order to understand safe operation, it’s necessary to understand the application first.

    Whether it comes to pumps on a construction site or in an industrial process, the number one goal is to make sure it is operating and running with minimal need of attention. But as with any other equipment, it’s necessary to understand the basic priniciples of safe operation in order for this to occur. In order to understand safe operation, it’s necessary to understand the application ...

  • Assessment of variable speed pumps in water distribution systems considering water leakage and transient operations

    In this study, the potential economic and hydraulic benefits of utilizing variable speed pumps (VSPs) in water supply systems are reported. A simple water distribution network simulation is carried out by EPANET and Bentley HAMMER models to examine variable speed operation. It was found that using VSPs could control and improve performance of the water distribution systems. Where the potential ...

  • Basic operation of a Cycle Stop Valve

    Automatic pump control methods are described as a pump system that automatically delivers water when a tap is opened, and automatically stops the pump after all taps are closed. A variety of pump control methods have been used in the past. The Cycle Stop Valve replaces: Variable Frequency Drives (VFD’s) or “Constant Pressure Pumps”. Large pressure ...

  • Merged two-level optimization for optimal pump operation of large scale urban water distribution system

    Subsequent to the least cost design problem of water distribution systems (WDSs), optimal operation is probably the most explored topic. Since 1970 a variety of methods have been developed to address this problem. Although the proposed methods give theoretic ways for solving optimal operation problems of WDSs, there are little successful application cases in practice, especially when the ...

  • Optimal operation efficiency and control of water pumps in multiple water reservoir system: case study in Korea

    Pumping regimes for water distribution systems have been established to reduce pump operation costs. Optimization of water reservoir networks has been studied extensively for operating pumps efficiently. According to research, optimization reduces pump operation costs by approximately 10–20%. However, comparing economic benefits per country would be too complex because the effects ...

  • VFD for pumping systems

    Pumping systems account for nearly 20% of the world's electrical energy usage. In some process plants, the VFD for pumps and fans together account for between 50% and 80% of the total electricity used. Very rarely have I come across pumps operating with fully open discharge valves. The same is the case for fans with dampers. ...
