水の硬度が高い場合には、放置しておくと除去困難なカ
ルシウムスケールが付着する。When water is passed from the inside of the pipe to the outside of the pipe, scale and slime adhere to the inside of the pipe, which reduces the permeation flow rate. In particular, if the raw water has high hardness, calcium scale that is difficult to remove will adhere if left untreated.
また、管内に付着したスケールを除去する方法としては
、化学洗浄等、限られた方法しか使用できず、固着した
スケールに対しては対応する手段がなかった。Furthermore, only a limited number of methods such as chemical cleaning can be used to remove scale that has adhered to the inside of the pipe, and there has been no means to deal with fixed scale.

ある。In order to solve the above problems, the present invention provides a Chebura-type ultrafiltration membrane cylinder, an adsorbent housed inside the ultrafiltration membrane cylinder, and supplying raw water to the outside of the ultrafiltration membrane cylinder. We propose a membrane separation device characterized by comprising: a means for extracting treated water from the inside of the ultrafiltration membrane cylinder; and a means for removing deposits on the outer surface of the ultrafiltration membrane cylinder. It is something.
本発明においては、外圧をかければ変形するチェープラ
型限外ろ過膜の内部に、変形防止用の砂。In the present invention, sand is used to prevent deformation inside the Chepra-type ultrafiltration membrane, which deforms when external pressure is applied.
活性炭、キレート樹脂等を充填し５通水方法を従来と逆
に管外から管内へ向くようにしたので、スケールやスラ
イムの付着サイドが管外となり、超音波、スクレーパ等
の強力な手段で、スケールやスライムの除去ができる。Filled with activated carbon, chelate resin, etc., the water flow method is reversed from the conventional method and is directed from the outside of the pipe to the inside of the pipe, so the side where scale and slime adhere is outside the pipe, and powerful means such as ultrasonic waves and scrapers can be used to Can remove scale and slime.
また、筒内に活性炭、キレート樹脂等の吸着剤を充填す

る。A vertical Chebura-type ultrafiltration membrane cylinder 2 is disposed inside the tower-shaped container 1, and inside the ultrafiltration membrane cylinder 2 there is an adsorbent such as activated carbon, chelate resin, or the like. It is filled with a mixture 3 of adsorbent and sand. The container 1 has a raw water supply port 4, a concentrated sludge discharge port 5. t# mud opening 6 is provided. Further, the upper end of the ultrafiltration membrane cylinder 2 communicates with the treated water take-out lower, and the lower end is provided with a filling discharge port 8.
