<p>PURPOSE:To rationalize production process so that the filter medium can be efficiently produced in the process for production of the filter which sticks the powder of glucan and porous apatite to a blank medium sheet. CONSTITUTION:A treating liquid is prepd. by dispersing and dissolving 0.5 to 40wt.% porous apatite and 0.5 to 15wt.% water soluble glucan in water. This treating liquid 2 is packed into a treating liquid tank 1. On the other hand, a roller 4 which has a horizontal revolving shaft 3 and is partly immersed into the treating liquid 2 is revolved. The blank medium sheet 5 is brought into contact with this revolving roller 4 to stick the treating liquid to the blank medium sheet. The blank medium sheet stuck with the treating liquid is dried by a heater 7.</p> |
