The module is constructed with the separation membrane facing the liquid side and the separation membrane facing the stock solution side, and the filtrate reaches the flow end through the space formed by the support cloth of the separation membrane and flows out.
In -14216, the liquid to be treated is connected to the central liquid collecting pipe and to the inlet of the liquid to be treated.In addition, in 54-17572, the liquid to be treated is connected by joining the separation membrane units to each other and by joining the assembly of separation membrane units to its casing. must be prevented from contaminating the filtrate. For this reason, a method is usually used in which an adhesive is poured and solidified, and for tubular types, a method using an elastic packing provides a fairly good seal in either case. However, sometimes components of the liquid to be treated may be mixed into the filtrate. When the filtrate is used as a product, even a very small amount of contamination can be a serious problem, and conventionally the focus has been on improving the characteristics of the separation membrane because it is derived from the separation characteristics of the membrane. However, the inventors of the present invention have studied the cause in detail and further studied countermeasures, and as a result, have arrived at the present invention.
くし
原因は、多孔性支持体と分離膜との接合における支持布
ｔこ対する膜剥離から生じる空間と接着剤の多孔性支持
体への浸入不足による空間の存在であると推定された。The causes of combing were presumed to be the presence of spaces resulting from peeling of the membrane against the support cloth during bonding of the porous support and the separation membrane, and spaces due to insufficient penetration of the adhesive into the porous support.

理しておけばその熱処理の幅がかなり狭いものであって
も、極めて有効に液洩れが防止出来る事を見出した。Even if we used a low-viscosity adhesive, spread the bonding area widely, and treated it carefully, we were unable to completely eliminate the leakage of the liquid to be treated. However, after various studies, we found that In the adhesive-sealed part of the separation membrane or the elastic packing part, that is, in the area to be sealed, the entire length in the direction perpendicular to the flow direction is heated and heated under conditions that at least soften or melt the separation membrane. It has been found that if pressure treatment is applied, liquid leakage can be extremely effectively prevented even if the width of the heat treatment is quite narrow.
勿論、シール予定領域全幅について同処理をしても何ら
支障はないが通常０．５−２ ｍ幅程度の処理で十分で
ある。Of course, there will be no problem if the entire width of the area to be sealed is treated in the same manner, but normally, treatment for a width of about 0.5-2 m is sufficient.
具体的な処理法として、前記モジュールタイプを２つに
大別して実施できる。As a specific processing method, the above module types can be roughly divided into two types.

- For the type of furnace cylinder, for example, in the flat membrane stage before the separation membrane is folded, rolled up, laminated, and formed into the furnace cylinder, a sealing area 3 in Fig. 1 with a width of about 0.5 to 2'' is This condition is satisfied by subjecting the impulse-rate separation f1 and the support body 2 to the above-mentioned pressure treatment in advance to form the compacted portion 4.
この場合、この加圧処理は通常の溶着シールを施す程、
強く接着する必要はない。In this case, this pressure treatment is not as effective as applying a normal welding seal.
There is no need to adhere strongly.

よって、完全に洩れを阻止する事が出来た。In the case of a tubular type, as shown in Fig. 2, a seal receiver with a larger diameter than the separation membrane tube 1 lined with a porous support 2 is inserted into the tube 5 so that the ends of the separation membrane tube 1 approximately coincide with each other. Further, a rotatable sealing roll 6 is inserted therein, and the receiver is rotated along the tube 3 and flattened by one round or a plurality of rolls. Furthermore, by suppressing that surface with an O-ring or an elastic packing such as a cylindrical rubber, it was possible to completely prevent leakage.
チューブラ−タイプの場合は、前述の平膜の場合と異な

、広くとっておいた方が、良い結果が得られる。In the case of a tubular type, unlike the case of the above-mentioned flat membrane, better results can be obtained if the width of the pressure treatment is widened to match the size of the elastic packing.

Stack them and weld them together on both sides in the length direction to make a flat cylinder. Ten of these flat cylinders were stacked and inserted into a rectangular cylinder having an inlet and an outlet for the liquid to be treated, and a polyurethane resin adhesive was poured into the area to be bonded at the sealed end and solidified to form a module. Using this module, we performed a filtration operation for 7 hours at the pressure of 05 using black ink as a model liquid to be treated, and there was no contamination in the filtrate.Also, when we peeled off the seal end, No leakage of dye was observed.
