    • A washing system for use in cleaning or washing a soiled substrate or substrates, the system comprising: a. a washing zone for contacting the soiled substrate with wash liquor; b. a feed supply for providing hot or cold feed water to the washing zone; c. a water-softening zone intermediate the feed supply and washing zone and in fluid communication therewith; d. an effluent storage and/or discharge zone; and e. a product dispensing zone intermediate the water softening zone and washing zone; and wherein the water-softening zone is effective to soften the water to a residual Ca2+ hardness of 1 mmol/L or less with a soft water flux of at least about 2 L/h, preferably at least about 10 L/h at a feed water pressure in the range from about 100 to about 1000 kP (1-10 bar). The water-softening zone is preferably a nanofiltration device having a cut-off in the range from about 100 to about 1000 Daltons, a clean water flux of at least 3 L/m2.h.100 kp (RO water at 25° C.), and a magnesium ion rejection of at least 50%. The washing system is preferably used for washing laundry.
    • 一种用于清洁或洗涤污染的基底或基底的洗涤系统,所述系统包括:a。 用于使污染的基质与洗涤液接触的洗涤区; b。 用于向洗涤区提供热或冷的给水的供料装置; C。 位于进料供应和洗涤区之间并与其流体连通的水软化区; d。 污水储存和/或排放区; 和e。 在水软化区和洗涤区之间的产品分配区; 并且其中所述水软化区有效地将水软化至1mmol / L或更低的残余Ca 2 O 2硬度,其中软水通量至少约2L / h,优选在 在约100至约1000kP(1-10巴)范围内的给水压力下至少约10L / h。 水软化区优选是具有约100至约1000道尔顿范围内的截止值的至少3L / m 2的干净水通量的h100 kp的纳滤装置 (25℃的RO水),镁离子排斥率至少为50%。 洗涤系统优选用于洗衣服。
