  • Publication number: 20140318950
    Abstract: A system and reactor vessel for electrical treatment of a fluid medium are described. The fluid medium to be treated comprises various industrial or domestic waste waters. The reactor vessel is provided with a housing being closed from one side thereof by a removable closure carrying secured thereon electrodes. The electrodes are electrically connected to the source of electrical power, wherein the closure is adapted for assembling with and disassembling from the housing such that the closure could be conveniently separated from the reactor vessel together with the electrodes to provide easy access to electrodes for inspection, replacement, repair, cleaning or for other type of maintenance.

  • Patent number: 8524180
    Abstract: The invention provides a process for minimizing the emission of particulate matter and precursors thereof from a flue gas stream of an engine comprising particulate matter and precursors thereof and at least one gaseous component. The process includes the steps of obtaining a flue gas stream of an engine comprising particulate matter and precursors thereof; increasing the moisture content of the stream by contacting it with a first aqueous medium in an amount and at a temperature at which at least 50% of the water content of the first aqueous medium is evaporated; whereby a moisture laden gas stream, optionally containing suspension droplets, is formed; cooling the moisture laden gas stream whereby suspension droplets are formed; and applying a centrifugal force to the moisture laden gas stream and to the suspension droplets to effect the swirling thereof, whereby a treated gaseous stream and an aqueous stream are formed.

  • Publication number: 20100139492
    Abstract: The invention provides a cyclone unit for the removal of contaminants from flue gases by combination of a gaseous stream with an aqueous stream, comprising a housing defined by a cylindrical peripheral wall, by upper and lower extremities, and by a core element, the housing having a longitudinal axis and being provided with at least one inlet opening for receiving a gaseous stream and a plurality of inlet openings for receiving an aqueous stream thereinto, the cyclone unit further comprising at least one swirling means concentrically positioned and mounted within the housing coaxially with the longitudinal axis so as to provide a first annular space between an inner surface of the housing peripheral wall and the outer facing surfaces of the swirling means and to provide a second inner annular space between inwardly facing surfaces of the swirling means and the core element, the swirling means incorporating a plurality of slit-like elongated openings extending substantially tangentially with respect to the inn

  • Publication number: 20040069142
    Abstract: A method for slowing down the increase in pressure drop across a gas filter caused by clogging as a result of a contaminant particles layer being formed on the filter. The method comprises applying acoustic waves from an acoustic wave source to a gas to be filtered as it flows into the filter; thereby producing steady secondary acoustic streaming around dust particles already deposited on the filter, thus reducing pressure drop across the filter initially caused by clogging.

  • Patent number: 6344349
    Abstract: A process and system for electrical extraction of intracellular matter from biological matter, and intracellular matter products formed thereby, based on preparing a mixture of biological matter featuring cells, and an electro-conductive liquid, and electrifying the mixture by transmitting controlled cycles of pulses and pauses of electrical current into the mixture by using electrodes, whereby the pulses of electrical current pierce holes into or perforate the cell membranes of the cells, enabling the release of intracellular matter for collecting and separating into target intracellular matter extract and solid waste. Pauses included in each cycle of transmitting pulses of electrical current enable firm control of electrical extraction processing conditions, including extent of extraction, temperature effects, and pressure effects, during the electrical extraction process.

  • Patent number: 6270544
    Abstract: A cyclone separator for separating a solid particulate from the gas or liquid medium is described. The separator is provided with a housing (H), an outlet (4) for discharging the solid particulate separated from the medium, a pipe (13) for evacuating the clean fluid from the housing (H) and a swirling means capable of imparting vortical motion to the medium. The swirling means is formed with a plurality of slit-like openings (16) arranged on the periphery thereof.

  • Patent number: 6141905
    Abstract: A process for the manufacture of a product useful as an artificial soil, soil conditioner or peat substitute, effected by subjecting an aqueous mixture containing a substantially solid feed excrement from animals and water to treatment with an alternating electric current at a frequency of a predetermined magnitude and for a predetermined period of time, such that an odorless solid product capable of absorbing several times its own weight of water is recoverable by water removal.
