Zusammenfassung:	A removing system for contaminant in air comprises: a pre-stage air washer (11) which employs a chemical liquid; a chemical liquid supply device (12) configured to supply the chemical liquid to the pre-stage air washer (11); a post-stage air washer (13) which employs a pure water as the absorbent; an ion exchange resin (14) through which the absorbent of the post-stage air washer (13) is passed; and a control unit (16) configured to estimate a concentration of the contaminant contained in the air flowed into the pre-stage air washer (11) based on an electric conductivity of the absorbent passed through the ion exchange resin (14) and then to calculate a flow rate of the chemical liquid to be supplied from the chemical liquid supply device (12) to the pre-stage air washer (11).
