Abstract: The present invention is directed to a pulsed electric-field system, apparatus and method for the effective disinfecting and dewatering previously-dewatered, biologically active waste-water sludges (e.g., municipal waste-water sewage sludge) in an efficient manner, so as to dramatically reduce the resulting volume of the inert waste material which has to be disposed of by the municipality. The method employed sequentially consists of hydraulically pressurizing the previously dewatered sludge, pre-heating the previously dewatered sludge to a predetermined temperature range, exposing the previously dewatered sludge to a high energy pulsing electrical discharges, pressure separation of the resulting solids and liquid fraction, and final pressure extrusion of the separated solids through nozzles.

Abstract: A method and apparatus for electronically treating water flowing through a water distribution system is disclosed which functions to inhibit the formation of scale deposits. The apparatus includes a fluid chamber connected into the water distribution system for isolating a quantity of water and an electrode in contact with the isolated water for imparting an electrical pulse train to the isolated water. The apparatus also includes a signal generation circuit for generating and regulating the pulse train and an error indicating circuit to verify proper operation of the system and to indicate the need for maintenance.

Abstract: A process and apparatus for killing organisms in situ within a host by means of successive short-duration high-current-density pulses of electricity of alternately opposite polarity. These pulses are passed through the host and concomitantly the organisms for a period of a few seconds. The cellular structure of the host is not destroyed, nor is the temperature thereof appreciably elevated. The current is conveyed to the host from electrodes immersed with the host in a weak electrolyte. The pulses are formed by phase-controlled thyristors.

Abstract: A driver device (1) includes a pulse generation circuit (5) that generates, within one period, a pulse waveform (Spl) with a first voltage level in a first period (T1) and a pulse waveform with a second voltage level in a second period (T2). A control circuit (2) makes the first period equal to a minimum on period (Tminon) to perform a supply mode for the minimum on period and, if at the end of the minimum on period the output current (Iout) has reached the set current value (Iset), the control circuit makes a switch to a decay mode and performs a skip of a switch to the supply mode at the end of the second period.

Abstract: The invention relates to a method for activation of concrete mixing water. The method includes preliminary action on the mixing water in continuous flow by pulsed high-voltage electrohydraulic discharges with supply DC voltage from 500 V to 5000 V at a pulse frequency from 2 Hz to 10,000 Hz and a current from 0.1 A to 10 A on electrodes of copper and/or iron and/or titanium. Then the water is treated in a mechanical and/or ultrasonic cavitator in the developed cavitation mode and at a water pressure from 0.8 atm to 6 atm without addition of plasticizers and/or surface-active agents.
