Abstract: A modular water purification system has a high pressure pump interchangeably received into one of two or more alternative power modules that can rely on different energy sources, such as an combustion engine module or an electric motor module. The pump applies water pressure to a reverse osmosis filter element. The system is reconfigurable for a given deployment, such as with a higher pressure pump operation for a high dissolved solute concentration, such as sea water desalination, or at a lower pressure for fresh water. Modules for deploying parallel paths each having a high pressure pump and reverse osmosis filter can be supplied as an addendum, or included in the supplied unit. The supplied unit is dimensioned so that the modules are stackable atop one another and in abutment to fill out a rectilinear volume on a pallet.

Abstract: A modular water purification system is optimized for versatility and weight using a pump component that is mountable by standardized fittings into alternative prime mover modules that can receive and power the pump. The pump can be a heavy high pressure pump for a reverse osmosis stage, interchangeably mounted on an internal combustion engine module or an electric motor module. The pump is enclosed and protected by a frame with end plates, elongated bar handles and a standardized base that fits into and is fixed by a sliding flange and clamping structure, locating the pump precisely to engage a rotational fitting on the pump shaft with a complementary fitting coupled to the prime mover.

Abstract: The present invention relates to devices for treating liquids, and methods for treating liquids, particularly by using such devices. Reticulated electrode structures with a high proportion of surface area to volume are formed with at least two metals, and are coupled in arrays to an electrical driving signal such as an alternating and/or direct current voltage source, for ion exchange with a liquid to be treated, to produce, e.g., potable water.

Abstract: The invention provides control systems and methodologies for controlling a process having one or more motorized pumps and associated motor drives, which provide for optimized process performance according to one or more performance criteria, such as efficiency, component life expectancy, safety, emissions, noise, vibration, operational cost, or the like. More particularly, the subject invention provides for employing machine diagnostic and/or prognostic information in connection with optimizing an overall business operation over a time horizon.

Abstract: A sensor system issues measurement commands at a predetermined regular rate. If a measurement indicates that a gas of interest is present, then the sensor system is signaled to wake-up thereby pulsing a heater for the sensor element that improves the accuracy of measurements. Measurements of humidity, temperature and gas concentration are made. If the gas of interest is detected then the data is used to indicate a compensated gas measurement. The gas level is classified as to its hazard and an adaptive detection algorithm is used to set an activity mode. If the gas of interest is not detected, the adaptive detection algorithm is used to set a sleep mode that saves power. Measurement rates are kept constant while heater power is controlled to reduce power consumption. Measurement rates are changed to increase concentration sensitivity.

Abstract: A silicon solar cell is formed with an N-type silicon layer on a P-type silicon semiconductor substrate. An antireflective and passivation layer is deposited on the N-type silicon layer, and then an aluminum ink composition is printed on the back of the silicon wafer to form the back contact electrode. The back contact electrode is sintered to produce an ohmic contact between the electrode and the P-type silicon layer. The aluminum ink composition may include aluminum powders, a vehicle, an inorganic polymer, and a dispersant. Other electrodes on the solar cell can be produced in a similar manner with the aluminum ink composition.
