Abstract

According to one embodiment, a treatment apparatus includes a dialysis unit, a treatment unit and a recovery unit. The dialysis unit is configured to dialyze a solution including a phosphoric acid, a silicon compound, and water. The treatment unit is configured to perform treatment of an object to be treated using a dialyzed solution. The recovery unit is configured to recover a solution used in the treatment of the object to be treated and supply to the dialysis unit. The dialysis unit includes a transmission part which allows anions to be transmitted. The recovery unit supplies the solution used in the treatment of the object to be treated, to a region in the dialysis unit. The region is divided by the transmission part.
