  • 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. ...

  • Fuzzy maximum power extraction control for a photovoltaic water pumping system

    AC loads present a delicate matter for photovoltaic systems, and this is because of the photovoltaic panel's operating point, which moves randomly according to irradiance changes; in this case, almost of photovoltaic water pumping systems use a DC–DC converter to ensure either the maximum power extracted from PV panel or the load needs. For AC motor pumps, an inverter must follow this chopper. ...

  • How can I finely control the vacuum applied by my vacuum pump or system?

    Some vacuum pumps or built in vacuum systems do not allow fine control over the vacuum applied. For rough work like vacuum filtration this is not always needed, but for more sensitive work, for example when using a rotary evaporator, application of the correct vacuum level is essential to smooth operation. The new ...

  • 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 ...

  • Leakage control of multi-source water distribution system by network partition and optimal pump schedule in China

    The main aim of an optimal schedule of conventional multi-source water distribution system is to reduce the energy consumption rather than minimizing the network leakage. This research is on the premise of meeting water demand, pressure and water quality considering the states of valve opening and closing, the states of pump opening and closing, and the pump speed as solution space. The ...

  • Solids Control for Drilling Mud Process System

    Nowadays, more and more drilling contractors recognize solids control’s importance to oil and gas drilling, HDD, CSM/CBM exploration, etc. How does solid control affect well drilling? Please find the following details. Cost Comparison of Two Oil Well Drilling Let’s find the difference of two kinds of oil well drilling with and without solids control system. Final effect or result is ...


  • Real Time Control of the Sewage System in St Malo

    Saint-Malo is an extremely attractive and popular seaside resort on the north coast of Brittany in France. Covering 1,400 hectares, the local population of 50,000 increases to 120,000 in the tourist season. One of the distinguishing features of this part of the Channel coast is a very high tidal range – 14 meters from low to high, with a potential impact back through the sewer network. Combined ...

  • Optimizing drilling efficiencies with a solids control system

    The correct solids control system can improve drilling rig efficiency, reduce costs and minimize the environmental footprint of your operation Although the use of drilling fluids within the HDD / trenchless industry is still relatively new, recent trends suggest that this standard is shifting as solids control is one of the most important phases in the drilling process. This shift is due ...

  • Mud desanders and desilters used in solids control system

    Mud desander is the second stage in the operation of drilling solid control equipment, commonly used is 10"and 12" cyclones. Oilfield mud desander is mainly used for the separation of solid particles in drilling fluid to particle size 45-74 microns in diameter. According to the processing capability, the ...


  • Medium Voltage Drive Systems in Pumping Plants

    Medium voltage (2.3kV to 6.6kV) motors are the norm in major Asian pumping plants in Asia to drive their water or waste water pumps. Pumping stations have to control both flow as well as pressure over varying consumer demand. Due to higher demand on productivity and efficiency, the trend for new installations is to design plants with electrical variable speed drives for their motor-pump sets to ...


  • The next generation biological odour control systems

    Odour is usually caused by the presence of hydrogen sulphide, mercaptans (Organic sulphur components) and ammonia, but also multiple other VOC’s (volatile organic compounds) bringing numerous odour complaints at e.g. WWTP’s, pumping stations and composting plants. An odour control system therefore will have to treat not only hydrogen sulphide, but also other pollutants to reduce the total ...

  • Groundwater pump & treat and SIPEX skimmimg system

    GRS has supplied and installed a system for the abstraction of free-phase floating creosote contamination. The system comprises frequency controlled submersible pumps for precise hydraulic control and our motorised interface tracking system which, due to large local water table fluctuations, was modified to provide a product/water interface tracking range of 5m.Abstracted groundwater is pumped to ...
