Abstract:
The present invention relates to a mixture for inhibiting the growth of algae which contains a ceramic powder for generating anions, and to an antifouling paint constituting an antifouling system employing the same, and it relates to a production method for such an antifouling paint. Specifically, the mixture for inhibiting the growth of algae of the present invention relates to a mixture for inhibiting the growth of algae which comprises tourmaline and monazite powders for generating anions, and zirconia for releasing stable anions from these ceramic powders, and also sulphur-metal soap for promoting the activity of the released anions. When an antifouling staff gauge was produced using the antifouling paint of the present invention and was then tested, it proved possible to solve the problem of the inability to read the markings of gauges due to the accretion of algae.

PROBLEM TO BE SOLVED: To recover adsorption performance of activated carbon economically to a high degree by a method wherein when activated carbon to which contaminant is adsorbed is regenerated, the contaminant is desorbed from the activated carbon by use of mixed solution of ethanol, sodium hydroxide solution and water. SOLUTION: In order to manufacture firstly desorption aqueous solution to be used in regenerating activated carbon, respective appropriate amounts from respective tanks 1 to 3 storing respectively water, ethanol, and NaOH solution are supplied to a mixing tank 4 and mixed. The desorbed aqueous solution obtained thereby is supplied to a regenerating reactor 5 to regenerate the activated carbon filled therein. A temperature of the regeneration reactor 5 is adjusted with a boiler 5 and a heater 12. The activated carbon for which regeneration is ended is transferred to a regenerated activated carbon storage tank 7 via a washing process, and waste liquid is discharged to a waste liquid storage tank 8. Then, the waste liquid and washings are supplied to a distillator 9 to evaporate ethanol contained therein, the ethanol is recovered with a cooler 10, reserved in a storage tank 11, and used again.

PURPOSE: A purifying apparatus based on membrane filtration and a purifying method using the same are provided to implement quantification and compensation by considering the flow of fluid generated in a membrane filtration-based treating process. CONSTITUTION: A purifying apparatus based on membrane filtration using a pipe-net simulator develops the design parameters of a membrane-based process by using a pipe-net which is a one dimensional simulation program. The stability and the mechanism flow of operational and piping processes are improved. The purifying apparatus designs tools before the implementation of the simulation program by inputting operational parameters. The simulation program is implemented, and the result of the simulation program is fed-back to compensate the design.

CONSTITUTION: A measuring device for a large displacement comprises a fixing member(20), a rotating member(10), a structure attaching member(40), a movable member(30), an inclinometer(40). The fixing member is fixed to a reference point for measuring a displacement. The lower part of the rotating member is connected to the fixing member by a first hinge unit(11), thereby rotating in one imaginary rotating reference surface. A structure attaching member is attached on the displacement measurement object structure, and comprises a sliding unit(41) longways formed in a longitudinal direction. One end part of the movable member is connected by a second hinge unit(13) to be rotated with respect to the rotating member. The other end part of the movable member is connected by a third hinge unit(42) to be rotated with respect to the structure attaching member, thereby perpendicularly moving along the sliding unit. The inclinometer measures an inclined degree caused by the rotation of the rotating member in a rotating reference surface.
