Abstract: A method and apparatus for screening of cell lines and culture conditions includes a target value setting step that sets a target value relating to a metabolic reaction of a culture cell; a first culturing step; an analysis step; an analysis value calculation step that performs a metabolism analysis based on an analysis result from the analysis step and calculates an analysis value; a culture condition computation step that computes, using a correlation model, a culture condition giving an analysis value most close to the target value, and modifies the culture condition set in the first culturing step to the computed culture condition; a second culturing step that cultures a cell under the modified culture condition; and a screening step.

Abstract: A cell culture apparatus (1) of the present invention comprises: a culture vessel (2) in which a cell culture medium comprising at least one of culture components composed of a conjugate with a stimuli-responsive polymer is stored and cells are cultured in the medium; a stimulus-applying mechanism (4) that applies a predetermined stimulus to the conjugate so as to induce a predetermined change of the stimuli-responsive polymer in response to the stimulus; and, a separation mechanism (5) that separates at least a part of the medium components except for the conjugate from the cell culture medium, while leaving the conjugate in the cell culture medium, on the basis of a property change of the stimuli-responsive polymer.

Abstract: A water treatment system includes a water treatment facility which includes a sulfate ion removing unit removing sulfate ions of treatment object water introduced from an inflow pipe and including an oil component and supplying treatment water after removing the sulfate ions to an outflow pipe and a bypass pipe branching off from the inflow pipe and causing the treatment object water to circulate through the outflow pipe, and a monitoring control device which includes a monitoring unit measuring a sulfate ion concentration of the treatment object water including the oil component and a flow rate control unit calculating a supply flow rate of the treatment object water to the sulfate ion removing unit and a supply flow rate of the treatment object water to the bypass pipe, on the basis of the sulfate ion concentration obtained by the monitoring unit.

Abstract: A water treatment system includes a water treatment facility which has a coagulation treatment unit injecting a coagulant into water to be treated including oil components and performing coagulation treatment and a monitoring control device which has an oil water separating unit introducing a part of the supernatant water after the coagulation treatment by the coagulation treatment unit and separating the oil components and a deposition tank depositing soluble components dissolved in the supernatant water after separating the oil water. The monitoring control device has a control unit which controls an injection rate of the coagulant, on the basis of at least a deposition amount of the soluble components by the deposition tank.
