<p>The present invention provides a purifying apparatus for a printed circuit board manufacturing process, and a purifying method using the same. According to a representative embodiment of the present invention, a water storage tank is connected with an acid solution storage tank to provide an acid solution when the pH of water exceeds the predetermined pH. Therefore, scales are prevented from being generated in a purification column. The apparatus includes: the purification column in which exhaust gas contacts the water supplied from the outside; the water storage tank; the acid solution storage tank; and a control part which supplied the acid solution when the pH of water is over the predetermined pH.</p> |
