摘要: The present invention provides a membrane filtration system (1) including: a filtering membrane portion (3) for removing impurities in feed water; a drain line (16) for draining a part of concentrate from the filtering membrane portion (3) to an exterior of a system; a concentrate return line (17) for returning a remainder of the concentrate from the filtering membrane portion (3) to an upstream side of the filtering membrane portion (3); a return flow rate adjusting portion (28) for concentrate provided in the concentrate return line (17); and a control portion (30) controlling the return flow rate adjusting portion (28) based on a drain flow rate of the concentrate or a flow rate of product water from the filtering membrane portion (3). With this construction, it is possible to suppress wasteful power consumption in a feed pump (7) for feeding water to the filtering membrane portion (3) and to prevent clogging in the filtering membrane in the filtering membrane portion (3).

摘要: Ion exchange equipment which can deal with counter-flow regeneration or split-flow regeneration while simplifying a water collector. The ion exchange equipment comprises a first water collection pipe (14) communicating with a first channel (10) formed in a lid member (7) at a resin containing section (2), and second water collection pipe (20) communicating with a second channel (11) formed in the lid member (7), wherein an inner diameter of the second water collection pipe (20) is set larger than an outer diameter of the first water collection pipe (14). The water collection pipes (14, 20) have axes set coaxially with the axis of the resin containing section (2) and form a double pipe, and a third channel (12) communicating with the resin containing section (2) is formed in the lid member (7).
