Place the feed liquid on one side of the semipermeable membrane and the draw solution on the other side so that they are in contact with the semipermeable membrane, respectively, and move the solvent from the feed liquid side through the semipermeable membrane to the draw solution side. • The reduced concentration draw solution is removed and heated to cause phase separation between draw solute and solvent. • Recirculating the phase separated draw solute to the other side. - The phase-separated solvent is further purified using, for example, a nanofiltration membrane (NF membrane) to obtain the target treated product (purified water, etc.).

Abstract
Description
よって、本開示は、高い浸透圧を発現し、且つ相分離性に優れたドロー溶液を得ることができる、正浸透膜法用ドロー溶質を提供とすることを目的とする。
本開示の正浸透膜法用ドロー溶質(ドロー溶質という場合もある)は、アミン化合物に由来する構造部位と、2種以上のオキシアルキレン基がランダムに結合しているポリオキシアルキレン構造部位とを含む化合物(以下、「本開示の化合物」とも言う)を含む。
本開示の化合物は、曇点(下限臨界溶液温度)を有することが好ましい。曇点とは、透明又は半透明な液体を温度変化させることにより相分離が起き、その結果、不透明になる温度のことを意味する。
本開示の化合物の曇点は、80℃以下であることが好ましい。本開示の化合物の曇点は、より好ましくは20~80℃であり、さらに好ましくは、30~80℃である。
本開示において、アルキレンオキサイドとしては、特に限定されないが、エチレンオキサイド(EO)、プロピレンオキサイド(PO)、1,2-ブチレンオキサイド(1,2-BO)、2,3-ブチレンオキサイド(2,3-BO)、スチレンオキサイド、エピクロロヒドリン、テトラヒドロフラン、オキセタン、ジオキシラン、トリオキサン、ブチルグリシジルエーテル、フェニルグリシジルエーテル、及びアリルグリシジルエーテル等が挙げられる。
本開示の化合物は、アミン化合物にアルキレンオキサイドをランダム付加重合させて得ることができる。アミン化合物1モルに対し、アルキレンオキシドのモル数は、好ましくは5モル以上であり、より好ましくは10モル以上であり、さらに好ましくは20モル以上である。一方、アミン化合物1モルに対し、アルキレンオキシドのモル数は、100モル以下であることが好ましく、より好ましくは80モル以下であり、さらに好ましくは70モル以下である。
本開示のドロー溶液は、上記ドロー溶質を含む。ドロー溶質の含有量は、ドロー溶液全量に対して、20~100質量%であると好ましく、50~100質量%であるとより好ましく、75~100質量%であると更に好ましい。
上記ドロー溶液は、溶媒を含んでいてもよい。溶媒は、ドロー溶液を用いる正浸透膜法の条件等に応じて適宜選択すればよいが、水、メタノール、エタノール等から選ばれる溶媒を1種又は2種以上用いることができる。溶媒としては、処理の対象となる溶液(供給液という場合もある)と同じ溶媒を含むことがより好ましい。溶媒の含有量は、ドロー溶液全量に対して、例えば80~0質量%とすることができる。
正浸透膜法では、供給液とドロー溶液とを半透膜を介して接触させ、浸透圧の低い供給液側から浸透圧の高いドロー溶液に溶媒が移動する。溶媒の移動に伴い、ドロー溶液の濃度は徐々に低下する。このため、正浸透膜法を継続して行うためには、ドロー溶液に含まれるドロー溶質と溶媒とを分離する必要がある。曇点を有する上記ドロー溶液によれば、加熱によりドロー溶質と溶媒とを相分離させることができる。
・半透膜の一方の側に供給液、他方の側にドロー溶液を、それぞれ半透膜と接触するように配置して供給液側から半透膜を通してドロー溶液側へ溶媒を移動させる。
・濃度の低下したドロー溶液を取り出して加熱し、ドロー溶質と溶媒とを相分離させる。
・相分離させたドロー溶質を再び上記他方の側に循環させる。
・相分離させた溶媒を、例えばナノろ過膜(NF膜)を用いて、更に精製して、目的の処理物(精製水等)を得る。
