Abstract
Description
尚、詳細は後述するが、一般水栓3は、浄水器1を介して入水口にあるバルブ11に接続されているが、入水口にあるバルブ11から一般水栓3に流れる水は、浄水器1で浄化されずに流れるようになっている。
図4乃至図7に示すように、内側ケーシング49は、中空糸膜47を囲むような筒状体によって構成されている。この内側ケーシング49の一端側には、ケーシングキャップ57が取り付けられており、ケーシングキャップ57は、キャップ37に液密に連結されるように構成されている。内側ケーシング49の他端側は、中空糸膜モジュール29よりも筒状容器27の閉鎖端側にある水を受け入れるように開口している。また、内側ケーシング45の側面には、多数の開口部59が形成されている。
専用水栓5から浄水を出す場合、一般水栓3が閉じているので、バルブ11から浄水器システムに流れ込んだ水は、浄水器1を通って専用水栓5に流れる。
一般水栓3から水を出す場合には、専用水栓5が閉じているので、プレフィルタ19の浄水出口管43内の水圧が、洗浄水出口管45内の水圧よりも高くなっている。従って、バルブ11からプレフィルタ19の筒状容器27内部に入り、さらに中空糸膜モジュール29に流入した水は、浄水出口管43の方向には流れずに、洗浄水出口管45の方向に流れる。そして、中空糸膜モジュール29内に流入した水が内側ケーシング49の開口から内側ケーシング51の開口部59の方向に流れると、水が柱状に束ねられた中空糸膜47の外表面に沿って流れるので、中空糸膜47の外表面に付着した濁質を洗い流すことができる。また、このとき水は、中空糸膜47を通過することはないが、多数の中空糸膜47の間を流れるので、中空糸膜47の柱状体内側に付着している濁質も洗い流すことができる。そして濁質を含む水は、内側ケーシング49と外側ケーシング51の間を通ってキャップ31の方向に流れ、洗浄水出口管43を通ってヘッダ25に到達する。そして洗浄水は、ヘッダ25から一般水栓3に向けて流れる。
三菱レイヨン製の中空糸膜EX270T(膜面積0.28m2)を使用して中空糸膜モジュールを作成し、内部容器の側面にはφ2.5mmの穴を3箇所、内部容器の長手方向に対して下方側に15mmの等間隔になるように開けて、フィルタを作成した。
カオリン10度、水温20℃、圧力0.1MPa、ろ過時間120分、洗浄時間10分、初期ろ過流量(OUT-INろ過)2.0L/minの通水条件で実験を行った。
濁度10度の水を、4000L通水しても、洗浄直後の流量保持率は、いずれも90%以上であった。
長手方向に垂直な平面において、点対象の位置に二つずつ15mm間隔で合計6個の直径2mm穴が壁面に開いた、長さ100mm、外径9.5mm、内径7mmのセンターチューブを設けた以外は実施例1と同様にして、通水試験を行なった。
濁度10度の水を、4000L通水しても、洗浄直後の流量保持率は、いずれも90%以上であった。
内部容器に、大きさ14mm、質量7gの塩化ビニル樹脂製とポリスチレン製のハート型の粒状物5個ずつ収納した以外は実施例1と同様にして、通水試験を行なった。
濁度10度の水を、4000L通水しても、洗浄直後の流量保持率は、いずれも90%以上であった。
内部容器の底蓋が無い状態(底が開口)とした以外は実施例1と同様にして、通水試験を行なった。
濁度10度の水を、1000L通水した時、流量保持率は60%であった。
