Water is used for industrial purposes and drinking water. When using such cancer water or seawater, a desalination process to remove the salt dissolved in the water is essential, but the purpose of the desalination process is to remove floating substances that may obstruct the desalination process. Pretreatment is required.

を招く。また、溶解無機物を除去することができない。In the case of the sand filtration method mentioned above, although it is highly effective in removing suspended matter of approximately 1 μm or more, it is less effective in removing suspended matter smaller than that, and it is necessary to form flocs by adding a flocculant in advance. This results in an increase in running costs. Also, dissolved inorganic substances cannot be removed.

In addition, in the method of using the filter member shown in Figure 3, the activated carbon layer placed on the water to be treated will capture and adsorb suspended solids to a greater degree, making clogging more likely to occur. cannot make full use of it. As a result, problems arise such as increased pressure loss or increased running costs.

溶解無機物を効率的に除去できる。[Function] According to the method of the present invention, a porous support precoated with a mixture of a non-adsorptive filter aid and an adsorbent filter aid having different particle sizes is used as a filtration member through which water to be treated flows. As a result, a large number of flow channels having diameters suitable for capturing suspended matter are formed in the thickness direction of the precoat layer, and a non-adsorptive filter aid and an adsorbent filter aid are exposed in each flow channel. Therefore, efficient capture by the non-adsorptive filter aid of floating matter in the water to be treated that has flowed into each channel and adsorption of organic matter and dissolved inorganic matter by the adsorbent filter aid proceed simultaneously. Therefore, the 7 channels formed in the precoat layer can be effectively utilized, and as a result, the clogging time is extended, making it possible to maximize the adsorption capacity of the adsorbent filter aid, and Suspended matter, organic matter, and dissolved inorganic matter in water can be efficiently removed.

The filter member has a single precoat layer, and if it becomes clogged, the precoat layer can be removed in a short time by backwashing.
Furthermore, since a new precoat layer can be similarly formed in a short time, the operating rate can be significantly improved compared to conventional double precoating.

よい。In the above embodiment, the precoat layer of the filter member was positioned on the lower surface side, and the water to be treated was allowed to flow from the precoat layer side, but the present invention is not limited thereto. For example, the pre-coated layer of the filter member may be positioned on the upper surface side to allow the water to be treated to flow,
Place the porous support vertically and allow the water to be treated to flow horizontally! Alternatively, the porous support may have a cylindrical shape, and the water to be treated may flow from the inside and outside of the support.

The clogging time of the filtration member can be extended, which in turn reduces running costs by efficiently removing suspended matter, organic matter, and dissolved filtrate in the water, and improves operating rates by simplifying the formation and removal of the precoat layer. It has remarkable effects such as achievable.
