PROBLEM TO BE SOLVED: To provide a water treatment apparatus which is equipped with a strongly acidic water generating means and can surely remove microorganisms in a water filtering means with a relatively small amount of strongly acidic water. SOLUTION: The water treatment apparatus 1 includes a filtering means (a precision filter 4 and a reverse osmosis membrane module 2) for filtering raw water, a strongly acidic water generating portion 17 for generating strongly acidic water by applying a direct-current voltage to an electrolytic solution loaded with an electrolyte, a strongly acidic dilution water tank 50 for generating strongly acidic dilution water by diluting the strongly acidic water generated in the strongly acidic water generation portion 17 with permeate in a permeate tank 9, an injection path installed between the strongly acidic dilution water tank 50 and the raw water inlet side of the filtering means for supplying the strongly acidic dilution water in the strongly acidic dilution water tank 50 to the filtering means, and electrometers V1, V2 for measuring the oxidation-reduction potential of the strongly acidic dilution water passing through the filtering means.
