| 20090236294 | METHOD AND APPARATUS FOR TREATING FLUIDS - A method and apparatus for treating a fluid to destroy, remove, or reduce undesirable agents, such as microorganisms, particles or ions, contained in the fluid and/or to inhibit the formation of scale are disclosed. | 09-24-2009 |
| 20090229982 | SYSTEM AND METHOD OF GENERATING A RINGING MAGNETIC PULSE FOR THE TREATMENT OF FLOWING LIQUIDS - A method and system of generating a ringing magnetic pulse for the treatment of flowing liquids includes a coil and an SCR coupled in series with the coil to form a first loop. An electronic switch is coupled in series with the coil to form a second loop. An AC voltage signal is applied to the coil having first and second half-cycles. Current is conducted through the first loop during the first half-cycle when the SCR is forward biased while preventing current from conducting through the second loop. Current is conducted through the second loop during a portion of the second half-cycle while current is prevented from conducting through the first loop. Current is interrupted through the second loop during another portion of the second half-cycle upon the coil current reaching a predetermined value to interrupt current flowing through the coil, thereby generating a ringing magnetic pulse. | 09-17-2009 |
| 20090095352 | LARGE SCALE PULSED ENERGY WATER TREATMENT SYSTEM - A flow of fluid such as water is subjected to pulsed energy by dividing the flow into a plurality of divided flows; subjecting each divided flow to pulses of electromagnetic energy; and coalescing the plurality of divided flows into an output flow. A treatment apparatus includes a flow divider apparatus that has a inflow coupler and a plurality of conduits in fluid communication with the inflow coupler. Each conduit has a coil assembly thereon. The apparatus has a outflow coupler that is in fluid communication with each conduit. Coil assemblies on adjacent conduits may be staggered between the inflow coupler and the outflow coupler. The apparatus may include a control circuit for each coil assembly, for generating ringing pulses in the coil assembly. | 04-16-2009 |
| 20090065444 | Use of electromagnetic pulses in cross-flow filtration systems - A fluid feed stream is flowed, subject to electromagnetic pulses, to a filter element via an input feed conduit for the filter element. A coil assembly is disposed about the input feed conduit and an AC power source is connected with the coil assembly. The AC power source has a period including first and second half-cycles of opposing polarities. A switch in series with the coil assembly forms a series connected circuit. A second switch connected with the coil assembly forms a second circuit. A control means closes the first switch and opens the second switch during a first half-cycle of the AC power source. During a second half-cycle, the control means closes and then opens the second switch to produce a first large ringing pulse in the coil assembly. A subsequent pulse may be produced either before or after the first pulse substantially decays. | 03-12-2009 |
