- the voltage applied to the center of the butter (the nodule) which has a relatively large impedance, requires a high voltage, making it relatively difficult and difficult to put into practical use. That is, the state captured by the filter element for filtration was recognized as a very suitable state for applying electric energy for killing. This is the essence of the present invention.
- a conductive metal filter element is used, and a plurality of filter elements that increase the filter capacity as much as possible are adjacent to each other in close proximity to each other.
- the forest is arranged in the filtration tank. This means that when the surface of the filter element is viewed as an electrode, there are surface electrodes close to each other, so it is recognized that the impedance between the electrodes when it is energized between these surface electrodes is advantageous. did. This is also the essence of the present invention.
- FIG. 1A is a cylindrical hollow (panel-like) filter element belonging to a group of two cylindrical hollow (panel-like) filter elements divided into two groups
- 1B is a plurality of cylindrical hollow (panel-like) divided into two groups
- EL1 force S cylindrical hollow (panel shape) fill
- EL2 is a cylindrical hollow (panel-shaped) filter element
- EI ⁇ 3 ⁇ 4L1 and 1A are electrically connected Wiring that connects ELB force 3 ⁇ 4L2 and 1B electrically.
- a voltage is applied between one group of the two groups and the other group.
- the organism when a voltage is applied between EL1 and EL2, the organism is killed in the same state as the electrolysis of the raw water (treated water) using the surface electrode of 1A and the surface electrode of 1B.
- a voltage is applied to raw water to generate various radicals (active oxygen, etc.) by electrolysis, and its oxidative power provides a killing effect.
- organisms such as cell membranes of organisms whose potential difference is directly captured by the filter aid are destroyed.
- coenzyme A is acidified in biological cells, and a potential difference of about 0.74 V is applied inside and outside the cell, inactivating coenzyme A and causing cellular respiration mechanisms. Damage and kill.
- the “voltage accompanied by at least one polarity reversal” includes an AC voltage.
- AC voltage wave The shape may be a commercial sine wave, but any of the characteristic waveforms, such as a sawtooth wave, square wave, or triangular wave, may be more suitable for killing a specific organism.
- the method of the present invention is not limited to the case of a panel filter, (Appendix 1) killing organisms in the raw water in a filtration tank incorporating a plurality of conductive cylindrical hollow filter elements
- Organisms in liquid by conducting a second step of energizing the cylindrical hollow filter element after the first step of separating the clean water by passing the raw water through the filter aid pre-coated on the hollow filter element This is a method of electrically killing.
- the second step may be during the first step or after the first step. Since the second step is simply applying a voltage, it is obvious that both can be performed.
- a plurality of conductive cylindrical hollow filter elements are divided into two groups, and the second step is the two groups of conductive cylindrical hollow filter elements.
- a voltage with a polarity reversal at least once between one group and the other group, a current is applied in both forward and reverse directions between the conductive part of the cylindrical hollow filter element and the conductive part of the other group. is there.
- Z is electrical insulation
- EL1 is an external terminal connected to a group of cylindrical hollow filter elements (1A)
- EL2 is an external terminal connected to another group of cylindrical hollow filter elements (1B)
- ELA is EL1 and 1A
- ELB is the wiring that electrically connects EL2 and 1B.
- the filter elements are divided into two groups, as shown in FIG. 1 (a), in which the filter elements are alternately arranged so that the arrangement of 1A and 1B is symmetrical. This is because the potential distribution is less likely to be uneven. If the potential distribution is uneven and asymmetrical, the killing effect will also be uneven and the current will increase in a specific proximity, causing a short circuit.
- the second step may repeatedly apply a Norse voltage between the one group of the two groups of the conductive cylindrical hollow (panel-shaped) filter element and the other group.
- Pulse voltage In other words, not only is the electrical energy small and energy is saved, but there is also the knowledge that the change in voltage (voltage-time differentiation) is greater than the steady potential difference. Of course, it is better to reverse the polarity at least once even when a pulse voltage is applied. “At least one polarity reversal” may be performed with an AC voltage.
- FIG. 3 is also an illustration of an embodiment similar to FIG. 1 (b).
- the counter electrode may serve as an additional function of the cleaning and stirring means.

Arranged in the tank, the counter electrode is a conductive part of the cleaning means, or an agitation means having a jet nozzle for agitating the liquid in the filter tank is disposed in the filtration tank, and the counter electrode is the agitator It may be a conductive part of the means.
- the agitation means performs flow agitation to prevent uneven flow in the auxiliary agent precoat.
- a schematic diagram of the flow agitate is shown in FIG. Fig. 8 (a) is an example of conventional auxiliary agent pre-coating, where the vertical diffusion of auxiliary agent occurs, and Fig. 8 (b) is a force filter that eliminates the non-uniform auxiliary agent by the stirring device of the proposed device.
- Fig. 8 (c) shows an example in which non-uniformity of auxiliary agent is eliminated without excessively degrading the filter efficiency by the proper arrangement of stirring means.
- FIG. 9 is an example of the present cleaning means having both the cleaning jet nozzle Nc and a nozzle Nn for cleaning the surface of another adjacent cleaning means.

This is illustrated in Figs. 11 and 12.
- R is a rod-shaped counter electrode.
- the inter-electrode distance force S is small, so that the kill voltage with a small impedance can be reduced, and the electrode arrangement is symmetric, so that the potential distribution is not uniform, which is preferable. Since the force is also rod-shaped, it does not impede the suction fluid flow during filtration. Since the rod (bar) cross-sectional area should be as small as possible, the suction fluid flow is not hindered. Therefore, it is desirable that the expression be a needle shape rather than a rod (rod) shape.
- the rod-shaped round cross section is made into a streamline fin shape (not shown), and the suction fluid flow during pre-coating or filtration is agitated by the fin.
- the fin is a vertically long guide plate, and the suction fluid flow to the cylindrical hollow (panel-like) filter element may be viewed in a macro shape so as to make the flow smooth.

- the filter aid organisms are concentrated during filtration and the filter element is formed into a thin film extending relatively thinly on the surface of the filter element, so that electric energy for killing is easily given.
- the organism is in the shape of a balta, it is relatively difficult to apply heat to the center of the balta. That is, it was recognized that the state captured by the filter aid for filtration is a very suitable state for applying electric energy for killing. This is the essence of the present invention, and effective and practical biological killing is realized.
- the present plan kills the kill target in the form of a thin film, the efficiency of electrical killing is extremely high and the power cost is low.
- the shearing force can also be realized by a simple modification of a known filtration device, so the initial cost is low. It can be used for ship ballast water treatment.
- a plurality of conductive cylindrical hollows (bars) A device that kills organisms in the raw water in a filter tank with a built-in filter element, and a plurality of conductive cylindrical hollow (panel-shaped) filter elements are divided into two groups.
