摘要： PROBLEM TO BE SOLVED: To provide a cartridge type filter having a filter low in pressure loss and having long life arranged therein.
SOLUTION: The cartridge type filter having the filter arranged therein has a structure formed by arranging the filter comprising an aggregate of short fibers, that is, a cylindrical filter which comprises a laminated structure, wherein short fibers having crimps are mutually bonded at contact places of them, on the periphery of a microporous hard cylindrical core. In the filter having the laminated structure formed so as to pass a fluid through gaps between layers, the filter is arranged so that the fluid passes in the same direction as the fiber axes of the short fibers constituting the laminated structure and/or the surfaces of the laminated layers. The short fibers are constituted of at least two kinds of synthetic fibers. One synthetic fibers have a melting point relatively lower than that of the other synthetic fibers and at least one of the surfaces of them is melted by heating to bond the contact places of the other kind of the synthetic fibers.

摘要： PROBLEM TO BE SOLVED: To obtain a filter which is replaceable with a bobbin winding filter of a cartridge type and which has the property of a low pressure loss and a long life.
SOLUTION: The filter is a filter made of an assembly of short fibers, the constituent short fibers have random lengths, the short fibers having a length longer than a length capable of being crimped are crimped, the short fibers in the fiber assembly have their axes randomly orientated and the short fibers are bonded mutually at all or a part of the cross points to form a fiber structure. The fiber structure is composed of synthetic fiber and/or natural fiber, and synthetic fiber having a melting point lower than that of the above fiber, and the synthetic fiber having the low melting point is heated and at least its surface is melted to bond the short fibers mutually at the contact portions.

摘要： PROBLEM TO BE SOLVED: To provide a liquid filtering filter having a low pressure loss and a long service life.
SOLUTION: This liquid filtering filter is constituted by piling crimped short fibers, compressing the piled fibers and forming the compressed fibers into a block-like shape so that a liquid can be made to pass preferentially to the direction of the thick arrow shown in the figure. The fibers are bonded to one another at the positions being in contact with one another, arrayed so that the longitudinal direction of each of the fibers is adjusted to only one direction (X-direction) perpendicular to the fiber-piled direction (Z-direction) and compressed only to the fiber-piled direction. All of the fibers to be used are composed of two kinds of synthetic fibers. The melting point of one of the synthetic fibers is made lower relatively than that of the other of the synthetic fibers so that the low-melting point synthetic fibers can be bonded to one another at the contact positions by heating and fusing the fibers.

摘要： PROBLEM TO BE SOLVED: To prevent tangling with sewage residue and to prevent the sticking and accumulation of sludge by forming independent free ends as the front ends of hollow fiber membranes, linearly assembling the other ends and connecting the assembled ends to a water collection part. SOLUTION: Independent free ends are formed as the front ends 2 of hollow fiber membranes 1. The other ends are linearly fixed to form a fixed part 3, and a water collection part 5 which collects water treated by passing through the hollow fiber membranes 1 is composed of the fixed part 3 and a water collection member 4 to obtain the objective hollow fiber membrane module 6. Since the front ends of the hollow fiber membranes 1 are not supported or retrained and the hollow fiber membranes 1 in the module 6 can be freely swung even in use in high concn. activated sludge, sludge is less liable to accumulate on the surfaces of the membranes 1 owing to a stream of water, sludge is also less liable to accumulate between the membranes 1 because the membranes 1 are swung freely by the water stream and tangling with sewage residue is hardly caused.

摘要： PROBLEM TO BE SOLVED: To effectively wash a membrane module in such a state that the membrane module is arranged in an aeration tank. SOLUTION: The washing by a second washing means 21 performing immersion washing by tap water is performed between the washing by a first washing means 20 performing backward washing by permeated water taken out from a membrane module 7 to the outside of an aeration tank 1 and the washing by a third washing means 22 performing immersion washing by a chemical added soln. Therefore, two-stage washing by the first and second washing means or three-stage washing by the first-third washing means can be selected corresponding to the advance degree of the clogging of the membrane module 7 and the membrane module can be effectively washed.

摘要： PURPOSE:To contrive the concentration of sludge and the reduction of its volume as pretreatment and to attempt energy-saving in post-treatment, by subjecting filthy water, obtained by aggregation, solid-liquid separation and dewatering of the sludge, to secodary aggregation and solid-liquid separation, separating the resultant supernantant liquid with a membrane by aggregating filtration, and then disposing the formed conc. liquid and dewatered cake. CONSTITUTION:Sludge in a purifying vessel is fed from a reservoir 1 to the first aggregation step 2, where flocks are formed by a flocculant, and then treated with a screen means composed of wire materials having a wedge section in the first solid-liquid separating step 3. The separated flocks are formed into dewatered cake 4a in a dewatering step 4. Filthy water from the steps 3, 4 is purified in the second aggregating step 5 by the same method as mentioned above. Flocks are precipitated in the second solid-liquid separating step 6 and returned to the vessel 1, while a supernatant liquid is mixed with a flocculant and filtered in an aggregation-filtering step 7. The resultant washed filthy water is returned to the vessel 1, and the filtrate is separated into permeated water 9b containing a very small amount of soluble components and conc. water 9c in a membrane-separating step 9. The water 9c and the cake 4a and incinerated in an incinerating step 10, or anaerobically digested, wet-oxidized and formed into compost, or disposed.

摘要： PROBLEM TO BE SOLVED: To enable water purification capable of coping with a diversification of pollutant while suppressing a formation of trihalomethane by flocculating and filtering the water by adding a flocculating agent to the water to be treated to which an oxidizing agent is not added, then subjecting the water to membrane separation by using a reverse osmotic membrane having a specified salt inhibition. SOLUTION: In the water purifying device, a flocculating and filtering device 1, the first treated water tank 2, a membrane separation device 3 and the second treated water tank 4, etc., are provided, and the flocculating agent 12 in a tank 11 is supplied to the water 5 to be treated at the time of supplying the water 5 to be treated to a sand filter 7 of the flocculating and filtering device 1. Then a filtered water 13 from the sand filter 7 is supplied to a safety filter 15, and the filtered water 16 obtained here is separated to a permeated water 18 and a concentrated water 19 with the membrane separation device 3, and the permeated water 18 is supplied to the second treated water tank 4. In such a case, the reverse osmotic membrane having the salt inhibition of 5-99.7% when a common salt water having 500mg/l salt concn. is treated under a condition of 25 deg.C and 500kPa is fitted at the membrane separation device 3. In this way, various kinds of harmful pollutants are effectively removed.

摘要： PURPOSE:To provide a sewage treatment apparatus using a hollow yarn membrane module and capable of performing stable treatment at the time of the washing of a hollow yarn membrane while preventing the damage to breakage of the membrane and capable of still more enhancing treatment capacity. CONSTITUTION:A suction pump 4 and a blower 5 are operated while sewage to be treated is supplied to an aeration tank 3 having a hollow yarn membrane module 2 arranged thereto from a raw water supply pipeline 1 and the filtered water (or transmitted water) transmitted through the hollow yarn membranes 6 of the hollow yarn membrane module 2 is sent to the water gathering head 7 of the module 2 and also drawn out of the aeration tank 3 through a filtered water drawing-out pipeline 8. During this treatment, compressed air is ejected from the air diffusion pipe 9 constituted in a grid form arranged on the upstream side of the water gathering header 7 to effectively wash the hollow yarn membranes.
