<p>A control method for a water treatment device of an embodiment is provided with a step for transferring a slurry of filtering aid material to a filtering aid material measurement tank from a filtering aid material storage tank and a step for supplying the filtering aid material slurry from the filtering aid material measurement tank and forming a pre-coat layer on a filter in a solid-liquid separating device as well as monitoring the supply time for the filtering aid material slurry. In addition, the method is provided with a step for supplying and passing water to be treated through the pre-coat layer from a storage tank for water to be treated as well as monitoring the supply time for the water to be treated and a step for supplying treated water from a storage tank for treated water to the upper part of the filter for the solid-liquid separating device, destroying the pre-coat layer and transferring the filtering aid material constituting the pre-coat layer to a filtering aid material separating tank as well as monitoring the supply time for the treated water.</p> |
