Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water treatment equipment providing system suitable for temporarily renting water treatment equipment.

[0002]

[Related Background Art] In a manufacturing plant for semiconductors and the like,
For example, a large amount of treated water (pure water) from which impurities such as salts are removed is used for washing manufactured products. For this reason, the above-mentioned factory is exclusively provided with a water treatment facility equipped with an activated carbon filter, an ion exchanger and the like as ancillary facilities.

[0003] Incidentally, the above-mentioned water treatment facilities are individually designed according to the water treatment specifications, such as the amount and quality of treated water required in various factories, and are constructed as unique facilities corresponding to the factory environment. Is done.

[0004]

However, in the above-mentioned factory, a large amount of treated water may be required as the production scale of the product is temporarily increased. Also, in a shipyard or the like, a large amount of treated water may be required only when a boiler is assembled to a ship. However, provision of a large-scale water treatment facility in advance in anticipation of such temporary large demand for treated water requires a large facility cost.
In addition, there is a problem that the operating cost is extremely low because all of the processing capacity is not always exhibited. Particularly in a shipyard, there is a problem that the operation efficiency itself is poor because the period during which the water treatment equipment is required is limited.

The present invention has been made in view of such circumstances, and an object of the present invention is to temporarily rent a water treatment facility to cope with a temporary demand for treated water (pure water) in a factory or the like. It is an object of the present invention to provide a water treatment facility providing system suitable for the following.

[0006]

In order to achieve the above object, a water treatment facility providing system according to the present invention comprises an inventory management database for managing stocks of a plurality of types of units constituting the water treatment facility, When there is a request for lending a water treatment facility, a facility specification that satisfies the water treatment specification is designed by combining the plurality of types of units according to the requested water treatment specification (facility design means). Then, referring to the stock management database, the stock of units required to construct the equipment specifications is determined (stock determining means). Then, a unit out of stock is manufactured in accordance with the result of this judgment, and a water treatment facility of the above equipment specification is constructed using the stock unit and installed at a designated place (facility construction means). When the treatment facility is withdrawn, a plurality of units constituting the water treatment facility are stored as inventory, and information of the stored units is registered in the inventory management database (equipment recovery means).

[0007] Incidentally, the plurality of units include an activated carbon filter, a millibore filter, a reverse osmosis membrane unit, an electric deionization device, a non-regenerative ion exchanger, and a membrane filter. Further, the equipment design means, according to the water quality and water quantity indicated in the water treatment specifications, determines the type and number of units required to construct equipment specifications that satisfy the water treatment specifications, and as a series of plural types of units, It is characterized by designing a water treatment facility that meets the water treatment specifications.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a water treatment facility providing system according to an embodiment of the present invention will be described with reference to the drawings. This water treatment equipment provision system builds a water treatment equipment having a predetermined water treatment capacity to be used, for example, for backing up existing water treatment equipment owned by a customer in response to a request from the customer such as various manufacturing factories. The water treatment facility is suitable for temporary lending to the customer. In order to temporarily construct such a water treatment facility in response to a request from a customer, in the present system, a plurality of types of constituents of the water treatment facility, for example, an activated carbon filter (CF) and a millibore filter (MF) ), Reverse osmosis membrane module (RO), electric deionizer (KCDI), non-regenerative ion exchanger (DZ), membrane filter (PF), degassing membrane (DC), etc. Each of these units is selectively used in accordance with the water treatment specification, and is prepared so that a water treatment facility having a predetermined facility specification can be constructed.

Each of these units is configured to have a size that can be easily transported by a truck, for example, and its water supply and drainage system is connected to each other at a facility site so that a predetermined water treatment facility can be constructed. (For example, pipe diameter) are standardized. Each of these units is registered in the inventory management database DB and managed for inventory, and is selectively shipped according to equipment specifications.

The present system functions in response to a request from a customer to lend a water treatment facility as shown in FIG. 1 (order). That is, when there is a water treatment equipment lending request, the user first inputs a water treatment specification requested by the customer [Step S1]. This water treatment specification is basically given as information on the amount of treated water and the quality of water to be generated. More specifically, the amount of treated water per unit time, the type of raw water, the electrical conductivity (specific resistance) and the TOC (total organic carbon) component for evaluating the quality of treated water, and the like are input as water treatment specifications. .

When such a water treatment specification is input, a design of a water treatment facility satisfying the water treatment specification is executed [Step S2]. This equipment design is, for example, shown in FIG.
As shown in (2), the amount of treated water is determined (process 2a).
The water quality is determined (processing 2b), the type of raw water is further determined (processing 2c), and a list 2d of each unit prepared as described above according to the results of these determinations, and a standard model of the water treatment facility constructed for each specification With reference to 2e, the type and number of units used for building a water treatment facility satisfying the above-mentioned water treatment specifications are determined (process 2f).

More specifically, as a standard model 2e of a water treatment facility, for example, a plurality of types of facility configuration examples are prepared according to the water quality specifications as shown in FIGS. 3 (a) to 3 (d). The optimal standard model 2e according to the above-described determination result
Is selected. Further, a unit to be added to the standard model 2e is selected as needed. When the amount of treated water per unit time in each unit is insufficient, it is also examined whether or not the above-described standard model 2e is used in parallel across a plurality of systems.

For example, if the daily operating time is 8 hours or more and the monthly maximum water collection exceeds 10,800 m ³ , the activated carbon filter (C) is used as shown in FIG.
F), a water treatment facility constructed using a millibore filter (MF), a reverse osmosis membrane module (RO), and an electric deionizer (KCDI) is selected. On the other hand, if the daily operating time is less than 8 hours and the monthly maximum water withdrawal is about 3,600 m ³ , an inexpensive non-regeneration type can be used instead of the electric deionizer (KCDI). The equipment using the ion exchanger (DZ) includes an activated carbon filter (CF) and a millibore filter (M) as shown in FIG.
F) A water treatment facility constructed using a reverse osmosis membrane module (RO) and a non-regenerative ion exchanger (DZ) is selected.

When raw water contains carbon dioxide of 6 to 8 ppm or more, for example, as shown in FIG. 3C, an activated carbon filter (CF), a millibore filter (M
F), reverse osmosis membrane module (RO), degassing membrane (DC),
A water treatment facility constructed using a non-regenerative ion exchanger (DZ) is selected. Further, when the raw water is well water, as shown in FIG. 3D, a water treatment system having a configuration in which a membrane filter (PF) is further provided at the uppermost stream of the above-described equipment shown in FIG. 3C. Equipment is selected.

When the water treatment equipment is designed in accordance with the water quality specifications in this manner, the units necessary for constructing the water treatment equipment are managed as inventory with reference to the above-mentioned inventory management database DB. A search is made as to whether or not it has been performed [step S3]. If the necessary unit does not exist as a stock [Step S4], the unit is manufactured [Step S5], and the newly manufactured unit and the stock unit are used for the water treatment indicated by the equipment specifications. The equipment is constructed [Step S6]. When all the units necessary for constructing the water treatment facility are managed as inventory [Step S4], it is needless to say that there is no need to manufacture a new unit. A water treatment facility indicated by the specifications is constructed [Step S6]. Then, after confirming the operation of the water treatment equipment, the above units are transferred to the equipment delivery destination, and the water treatment equipment is lent out by assembling the water treatment equipment at the equipment site [Step S]
7].

During the rental period of the water treatment equipment, for example, as shown schematically in FIG. 4, the management concept is detected by the management water quality / water quality monitoring unit 11 attached to the water treatment equipment 10. Information indicating the equipment operation state, such as the amount of treated water and the quality of treated water, is periodically collected together with the equipment ID, and the management center 12 monitors the operation state. Then, under the operation management, maintenance such as replenishment of consumables such as a carboner or replacement of a deminer is performed to guarantee the operation quality of the water treatment facility. For the replacement of deminers etc., the used deminers are regenerated at a dedicated treatment plant, etc., and only the replacement work is performed at the water treatment facility site, so that the water treatment equipment including its ancillary equipment is large. It is desirable to prevent such troubles and to reduce the operation management burden (work load) at the water treatment facility site.

When the lending of the water treatment facility over the predetermined lending period is completed as described above [Step S8], the water treatment facility (unit) is collected [Step S9]. And the multiple units that had built the dissolved water treatment facility were stored as inventory,
That fact is registered in the above-mentioned inventory management database DB [Step S10]. By registering the unit collected in this way in the inventory management database DB, the unit can be reused and effectively used for construction of a water treatment facility for a new order.

As described above, according to the present system for constructing and renting a water treatment facility having equipment specifications corresponding to the required water treatment specifications, water treatment generally requiring a large facility cost is required. The equipment can be temporarily rented for a period required by the customer according to the change in the water treatment specification without building the equipment as a permanent equipment in anticipation of the maximum water treatment specification. Specifically, when a large amount of treated water (pure water) is required temporarily due to an increase in the production volume at a semiconductor manufacturing plant, or when a boiler is installed on a ship at a shipyard, In cases where treated water (pure water) is required, or where it is necessary to secure a large amount of drinking water occasionally at a disaster site, a water treatment facility with equipment specifications that meet these requirements can be simplified. To build
Can be installed at designated sites.

In addition, when the water treatment facility becomes unnecessary, the water treatment facility can be disassembled into the above-described units and collected, and each unit can be repeatedly reused for another water treatment facility. . Therefore, effects such as the facility cost and the operating cost being able to be sufficiently reduced can be obtained. Further, according to the present system, a plurality of types of units can be combined in accordance with the required water treatment specifications, and a water treatment facility with equipment specifications satisfying the water treatment specifications can be easily constructed. Therefore, the equipment specifications become excessive, and as a result,
It is possible to effectively avoid problems that increase equipment costs and operation costs. When high-purity treated water is required, it is only necessary to add a unit with higher treatment performance according to its quality, so facility design is easy, and facility cost can be reduced in this regard as well. Becomes

As described above, by designing the equipment based on the standard model 2e, even when a special water treatment specification is given, generally, a plurality of types of units prepared in advance are prepared. Can be dealt with by changing the combination of the above, so that the facility design can be easily supported. Accordingly, there is an advantage that water treatment equipment having equipment specifications corresponding to various water treatment specifications can be easily constructed.

The present invention is not limited to the above embodiment. For example, as a unit to be prepared in advance,
In addition to preparing a plurality of types of units having different processing (function) contents, it is also possible to prepare several units having different amounts of treated water. In addition, a pump, a storage tank (tank), and the like necessary for connecting the units may be handled as one unit.
In addition, the present invention can be variously modified and implemented without departing from the gist thereof.

[0022]

As described above, according to the present invention, the inventory of a plurality of water treatment equipment such as a filter unitized in advance is managed, and these units are combined in accordance with the water treatment specification to thereby control the water treatment specification. Since water treatment equipment with equipment specifications satisfying the above conditions is designed, water treatment equipment with various specifications can be constructed and rented out by effectively utilizing a plurality of units managed in inventory. Moreover, since the water treatment equipment can be used only for a period during which a large amount of treated water is temporarily needed, the effect that the equipment cost and the operating cost can be significantly reduced can be achieved. Can be done.
