  • 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. ...

  • 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 ...

  • Griffin Dewatering pumps 15 million gallons of water from flood control project with 75 foot deep wells

    On April 29 2011, Houston-based Griffin Dewatering Corp. began pumping 15 million gallons of water from the site. It also used 42 10-in.-dia, 75-ft-deep wells outside the dam perimeter to lower the groundwater table and relieve external hydraulic pressure. Griffin is working on several Corps projects in New Orleans, but Michael Lippard, Griffin senior project manager, says Seabrook is ...

  • Odour control on waste water treatment plants and pumping stations using DMT biotrickling filtration

    Lengthy detention times and warm weather / climate leads to septic waste water producing copious amounts of not only hydrogen sulphide, but also ammonia, organic sulphides, mercaptans, bringing numerous odour complaints on waste water treatment plants ( WWTP’s ) and pumping stations. An odour abatement unit therefore will have to treat not only hydrogen sulphide, but also other pollutants ...

  • 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 ...

  • The Benefits of an Integrated Air and Water Pollution Control Partner

    Although there has been substantial progress during the past several decades in reducing pollution, the EPA, other federal agencies and local governments continue to add and revise requirements and standards, making compliance a challenge for the industrial sector. These companies also face increasing public pressure not just to meet but to exceed pollution control standards, as studies continue ...

  • A robust approach based on time variable trigger levels for pump control

    An approach for the control of a pumping plant feeding a tank at the inlet of a water distribution system is presented. The approach is aimed at minimizing the energy costs by maximizing pumping during off-peak electricity tariff periods. It is based on trigger levels which are variable during the day according to a prefixed pattern in order to ensure that the water level in the elevated tank ...

  • Water Level Monitoring and Control Solutions for the UK Internal Drainage Boards

    Pulsar Process Measurement have been involved in design, manufacture and supply of non-contacting Ultrasonic Level and Pump Control systems for the Internal Drainage Board industry for many years. Three typical examples of the application of this equipment are installed at North Level IDB Cross Guns Pumping Station. The original Cross Guns Pumping Station was built in 1938 to house three 760mm ...

  • Continuous nonlinear model predictive control of a hybrid water system

    Incorporating weather forecasts in the control of land surface water levels requires predictions of the net inflow to the water system. This net inflow is the combined flow of an incoming load (rain, evaporation, etc.) and outgoing pump rates. Because the pump costs are considerable, optimal pump schedules have minimal energy consumption. Model predictive control (MPC) is able to compute, revise ...

  • A PSO approach for optimum design of dynamic inversion controller in water distribution systems

    Water distribution systems have become immensely complex due to ever increasing water demand and sporadic availability of water at the sources. Generally, water management issues are handled through human intervention, which naturally leads to incompetent trial and error procedures. Moreover, the non-linear system dynamics and sequential pumping operations involved in the water distribution ...

  • Controlling the addition of Chlorine into a Process

    There are several methods for controlling the addition of chlorine into a process. These methods include flow proportional injection, ORP (oxidation reduction potential) or a residual chlorine analyzer. Each method measures a different process characteristic. Depending on the specific type of process being controlled, there generally is a best choice for controlling the injection of either ...
