    Abstract: This water treatment system includes a water intake section 8 for taking in a raw water containing a water-soluble polymer; a stirring unit 1 for stirring the raw water flowing into the unit from the water intake section 8; a separating unit 2 for separating a solid from the raw water after the stirring; a viscosity measuring section (5,6,50) for measuring the viscosity of the raw water flowing in the stirring unit 1, and that of the raw water after the stirring; and a control unit 4 in which on the basis of a result measured through the viscosity measuring section and a predetermined target viscosity, a control is made about the amount of an additive to be charged into the stirring unit 1, and/or the stirring intensity of the stirring unit. Thus, the viscosity of the raw water is adjusted.

    Abstract: An oil content measurement device includes a fluid device which mixes water to be treated containing oil content with a solvent and extracts the oil content into the solvent, a sensor unit which has a casing storing a quartz crystal oscillator therein with a ring-like spacer in between, a dispensing nozzle which is disposed above the oscillator at a predetermined gap there between and feeds a predetermined amount of the solvent after the oil content has been extracted on the oscillator, a sensor circuit which measures a resonance frequency of the oscillator, and controller which controls at least the fluid device and the sensor circuit. Provided is a arithmetic logical unit, based on a change amount of the received resonance frequency of the oscillator in the sensor unit to which the solvent after the oil content has been extracted has been fed, measures the oil content remaining on the oscillator.
