Description
上記式(1)において、JWは純水体積流束[m3/(m2s)]であり、Poutは濃縮水配管L4に設置された水圧計(不図示)の測定値である。純水透過係数Aの算出方法としては、濃縮水配管L4の流量調整バルブ(不図示)およびバイパス配管L2‐Bの流量調整弁を調整することにより、Pout=0.5MPa、濃縮水配管L4における濃縮水流量QL4を14.5cc/min.とした場合における透過水配管L3の透過水流量QL3[m3/s]を測定する。そして、この透過水流量QL3を分離膜24aの試験体24‐Tの面積で除算することにより純水体積流束JW1を求める。
そして、以下に示す式(3)により分離膜である試験体24‐Tの膜面近傍における原水の塩濃度を意味する膜面濃度Cmを算出する。
上記式(3)において換算係数Bは、原水に含有されるNaCl,MgSO4,CaCl2等の塩濃度と浸透圧の関係により定まる定数であり、本実施形態のように原水に含まれる塩が塩化ナトリウムである場合には換算係数B=1.2294となる。
上記式(4)におけるCinは送水管L2を流れる原水の塩濃度、Coutは濃縮水配管L4を流れる濃縮水の塩濃度である。本実施形態では、原水に含まれる塩化ナトリウムの塩濃度は上述のように250ppm前後に予め調整されているので、濃縮水配管L4を流れる濃縮水の塩濃度Coutのみ測定すればよい。また、濃縮水や原水における塩濃度の測定は、一例として、電気伝導度(率)を測定することにより行えばよい。
ここで、図16(a)は上述した濃度比Crを縦軸に、純水体積流束JWの測定値を横軸として各分離膜の測定結果を示すグラフである。同図(a)において、「△」マークは比較例である原水流路スペーサ300の試験体300‐Tの測定値を示し、「◇」は原水流路スペーサ40の試験体40‐Tの測定値を示し、「十」は変形例10の原水流路スペーサ160の試験体160‐Tの測定値を示す。図16(b)は、同図(a)に示す各試験体40-T,160-T,300-Tの濃度比Crの測定値を測定時の純水体積流束Jwとともに示す表である。
