摘要： A reverse osmosis membrane separation device includes: a reverse osmosis membrane module; a flow rate detecting unit configured to detect a flow rate of permeate water to output a detected flow rate value corresponding to the flow rate; a pressure pump configured to be driven at a rotation speed corresponding to an input drive frequency and to feed supply water to the reverse osmosis membrane module; an inverter configured to output a drive frequency corresponding to an input current value signal to the pressure pump; and a control unit configured to calculate a drive frequency of the pressure pump by a velocity type digital PID algorithm, such that a detected flow rate value output from the flow rate detecting unit becomes a target flow rate value that is set in advance to output a current value signal corresponding to a calculation value of the drive frequency to the inverter.

摘要： According to one embodiment, a water treatment system includes: a membrane separation device and a water softening device including a valve unit switching between a softening process in which soft water is obtained by passing raw water through a cation exchange resin bed downward and a regeneration process in which a whole of the cation exchange resin bed is regenerated by generating an opposite flow of a regenerant by supplying the regenerant from both sides of a top portion and a bottom portion of the cation exchange resin bed and collecting a liquid at an intermediate portion of the cation exchange resin bed, and a regenerant supply supplying the regenerant in a volume which gives a regeneration level of 1 to 6 eq/L-R, to a hardness leakage prevention region set in a predetermined depth on the bottom portion of the cation exchange resin bed, in the regeneration process.
