<p>PROBLEM TO BE SOLVED: To obtain a water cleaning porous body having excellent water cleaning capacity over a long period of time. SOLUTION: The water cleaning porous body has silicon carbide exposed to the surface thereof. Preferably, the porous body substantially comprises ceramics and is constituted by bonding silicon carbide to ceramics by a ceramic binder. Further, the porous body has a mean pore size of 10-500μm and the void ratio thereof is preferably 30-95%.</p> |
