Definitions
- the present invention relates to a membrane treatment method and a membrane using a membrane module capable of blocking microorganisms and fungus bodies in seawater with a membrane and supplying ballast water containing a microorganism having a predetermined size or more to a ballast tank. More specifically, the membrane treatment method and membrane treatment apparatus using the membrane module can reduce the frequency of washing and increase the recovery rate of treated water by filtering seawater with a low concentration of fouling substances through the membrane module. About.
- ballast tanks in order to maintain the stability of the hull during navigation. Normally, when crude oil is not loaded, the tank is filled with ballast water, and when the crude oil is loaded, the ballast water is discharged to adjust the buoyancy of the hull and stabilize the hull. Yes.
- ballast water is water necessary for the safe navigation of a ship, and seawater of a port that handles cargo is usually used. The amount is said to exceed 10 billion tons per year worldwide.
- ballast water contains microorganisms and eggs of small and large organisms that live in the port where the water was taken. Will be carried to.
- Ballast water discharge standards will be as shown in Table 1 below. .
- Patent Document 1 discloses a technique for countermeasures against fouling by utilizing bubble expansion caused by pressure reduction.
- Patent Document 1 Japanese Patent Laid-Open No. 2003-265935
- Patent Document 1 requires a pressure reducing means for reducing the pressure of the tank loaded with the membrane module, and has a drawback that the equipment is expensive.
- an object of the present invention is to provide a film processing method and a film processing apparatus using a film module capable of taking measures against fouling without causing an increase in cost with simple equipment.
- the invention of claim 1 is a membrane treatment method using a membrane module having a membrane treatment tank and a membrane module installed at the center of the tank, and continuing filtration while flowing raw water.
- a membrane treatment method using a membrane module characterized in that raw water is introduced from the outside to the inside of the membrane treatment tank along the outer peripheral tangential direction to form a swirl flow in the tank.
- the invention according to claim 2 is a membrane treatment tank and a membrane module installed at the center of the tank.
- a raw water introduction pipe that introduces raw water along the outer circumferential tangential direction from the outside to the inside of the membrane treatment tank Is a membrane treatment apparatus using a membrane module.
- the invention described in claim 3 includes a membrane treatment tank using a membrane module having a cylindrical membrane treatment tank and a membrane module installed at the center of the tank, and continuing filtration while inflowing raw water.
- a raw water introduction pipe for introducing raw water along the outer peripheral tangential direction from the outside to the inside of the membrane treatment tank is provided at a lower part or an upper part of the side wall of the tank, and a raw water discharge pipe is provided
- a membrane processing apparatus using a membrane module which is provided at an upper portion or a lower portion.
- the invention according to claim 4 is characterized in that the membrane treatment unit includes a cylindrical membrane module or a square membrane module.
- a membrane treatment apparatus using the membrane module according to claim 1, 2 or 3 It is.
- FIG. 1 is a schematic perspective view showing an example of a membrane treatment method using the membrane module according to the present invention and an apparatus for carrying out the method.
- FIG. 3 is an explanatory diagram showing another preferred embodiment of the present invention.
- FIG. 1 is a schematic perspective view showing an example of a membrane treatment method using the membrane module according to the present invention and an apparatus for carrying out the method.
- reference numeral 1 denotes a membrane module that can be mounted on a ship such as a tanker.
- . 2 is a cylindrical membrane processing tank installed around the membrane module 1.
- [0025] 3 is a raw water introduction pipe, and 4 is a raw water discharge pipe.
- 5 is a raw water pump, 6 is a circulation pipe, and 7 is a discharge pipe for suspended solids.
- the raw water introduction pipe 3 introduces raw water along the outer circumferential tangent direction by directing force from the outside to the inside of the membrane treatment tank 2, and is installed in detail as shown in FIG. Since the raw water is introduced in the tangential direction of the outer periphery of the tank, the raw water introduction pipe 3 need only be straight in the vicinity of the junction of the tank 2.
- the raw water introduced into tank 2 forms a swirling flow as shown in Fig.2.
- the raw water swirling in the vicinity of the membrane module installed in the center of the tank 2 is in a state where the concentration of the furing substance is lowered.
- the membrane module filters raw water having a low fouling substance concentration that causes membrane clogging, and the membrane treatment elapsed time per circulation cycle becomes longer. In other words, the recovery efficiency (recovery rate) of treated water increases.
- the raw water introduction pipe 3 is provided on the upper part of the side wall 20 of the tank 2
- the raw water discharge pipe 4 is preferably provided on the lower part of the side wall 20 of the tank 2.
- the raw water is introduced into the tank 2 and filtered, but a part of the raw water is discharged from the raw water discharge pipe 4 and introduced into the tank 2 again by the raw water pump 5 through the circulation pipe 6.
- the concentration of suspended solids in the raw water circulating in the circulation pipe 6 rises, or when the concentration of suspended solids in the raw water itself is high, it is discharged from the discharge pipe 7 to the outside to the membrane. It is also preferable to keep the raw water supplied at a low concentration of fouling substances.
- the raw water supplied from the raw water pump 5 to the tank 2 is seawater or fresh water in the case of ballast water treatment.
- the shape of the membrane treatment tank 2 is not particularly limited, but a cylindrical type is preferable in order to form a favorable swirling flow in the tank.
- a guide plate 8 as shown in FIG. 3 in order to facilitate the formation of a swirling flow.
- the membrane module 1 may be a cylindrical membrane module or a rectangular membrane module.
- Microorganisms of a predetermined size or larger can be separated by the membrane module 1, but if an ozone acid treatment is further added, fine microorganisms (such as bacterial cells) that have passed through the membrane can be sterilized, resulting in a clear Favorable to get the ballast water.
