摘要:
For providing a water filtration purifying apparatus and a method thereof, enabling to reduce the manufacturing costs of the apparatus as a whole, by combining a function of filtration and a function of separation/concentration, the filtration function and the separation/concentration are separated, in the structure thereof. Thus, since all sewage waters generated in respective filtration separators can be collected by only one (1) set of a magnetic separator, even if there are plural number of the filtration separators, it is possible to dissolve a problem of rising up the costs of the apparatus, as a whole. With this, it is possible to provide a water filtration purifying apparatus, for enabling high water-quality purification and also reducing low manufacturing costs thereof, by further small-sizing the magnetic separating portion.
摘要:
A freshwater supply system that stores fresh water transported by transport ships in storage devices and takes out the fresh water from the freshwater storage devices at need to use the same. The system comprises management device that puts management information together and sends and receives various information of countries for demand of the fresh water, analysis information of the fresh water, and various information of transportation device for transportation of the fresh water to the countries. Magnitudes of movements, prices, origins of movement, and destinations of movement of the fresh water are decided from the information from the management device.

A magnetic separation purifying apparatus includes a cylindrical-shaped sludge recovery rotating body rotating to place sludge and a magnetic substance on a surface thereof to convey the same; a magnetic rotating body, which has an axis in the sludge recovery rotating body and includes a rotating body and a plurality of magnets mounted on its circumference, at least a side of which is arranged close to an inner peripheral surface of the sludge recovery rotating body, by which a magnetic substance is magnetically attracted to a surface of the sludge recovery rotating body whereby sludge is transported onto the surface of the sludge recovery rotating body; and a scraping device that scrapes sludge and a magnetic substance being transported on the surface of the sludge recovery rotating body.
摘要:
There is provided a magnetic separation purifying apparatus capable of favorably separating a magnetic substance irrespective of fluctuation of a water surface in a magnetic separation part to thereby stably discharge high density sludge. The magnetic separation purifying apparatus comprises: a rotating filtering body having a cylindrical-shaped filtering net to filter sludge and a magnetic substance from a processed fluid containing the magnetic substance; a cylindrical-shaped sludge recovery rotating body facing the rotating filtering body to be horizontally close thereto, the sludge recovery rotating body rotating to place sludge and a magnetic substance on a surface thereof to convey the same; a magnetic rotating body, which has an axis in the sludge recovery rotating body and comprises a rotating body and a plurality of magnets mounted on a circumference of the rotating body, at least a side of which toward the rotating filtering body is arranged close to an inner peripheral surface of the sludge recovery rotating body, by which a magnetic substance filtered by the rotating filtering body is magnetically attracted to a surface of the sludge recovery rotating body whereby sludge is transported onto the surface of the sludge recovery rotating body; and a scraping device that scrapes sludge and a magnetic substance being transported on the surface of the sludge recovery rotating body.

摘要:
In a filtering and purifying system, bacteria in raw water are sterilized efficiently with ultraviolet rays, chemicals and the like at a pretreating step. The number of microorganisms such as bacteria remaining in the treated water is reduced remarkably, and the residue of plankton and organic substances as nutrients for bacteria in treated water is reduced by a coagulating and filtering treatment. It is thus possible to solve a problem that the treated water is deteriorated with time due to propagation of the bacteria.
摘要:
A duplex communication control device for a communication system comprising a plurality of stations which communicate data therebetween, wherein the stations are connected to a duplexed communication network and each station comprises a bus status list storing information indicating whether the station can communicate over a first or second communication line of the network; a token generating means which carries the newest bus status information on a token frame and transmits the token frame over the communication lines; a list updating means which receives the token frame transmitted over the lines and updates the contents of its own bus status list according to the bus status information carried on the token frame; and a transmission-reception means which selects one or both of the lines according to the bus status list for communication.
摘要:
A method for treating ship ballast water in which aquatic organisms in the ship ballast water are exterminated by adding hydrogen peroxide or a compound producing hydrogen peroxide in an amount such that a hydrogen peroxide concentration comes to be 10 to 500 mg/L to the ship ballast water, and then providing physical means for causing shear strength and/or cavitation to the ship ballast water.

An on-site system construction support tool 11 has a display device that displays a configuration example of an on-site system of a plurality of machines 1601-1607, 1610, 1611. The display device opens a process window 1100 having a plurality of process buttons 1101-1112, which identify processes 1501-1511 required for the on-site system, when one of the process buttons is operated, causing the display device to open a setup window 1210, 1220, 1230, 1240, 1250, 1260 for specifying the machine to be used in the associated process. The burden that is imposed on the environment by the on-site system is calculated in accordance with information concerning the fuel consumption of the specified machine and the amount of work and displayed. This makes it possible to flexibly support the construction of the on-site system and calculate a value of the expected environmental burden.
