<p>PURPOSE:To set the amount of dissolved oxygen in water to the theoretical saturated value of water or more within a short time by constituting an oxygen enriching filter apparatus of an Al sintered porous body wherein at least a part of the surface of an Al-base porous body is composed of aluminum whiskers. CONSTITUTION:Water 11 is received in a water tank 11 and an oxygen enriching filter apparatus 1 is vertically introduced into the water tank 10 and air is introduced into the apparatus 1 under pressure for about 5min by an air pump 15. This air passes through a connection pipe 12 to be introduced into the oxygen enriching apparatus 1 in water and is discharged into the cylinder of a filter main body 6 from a conduit 4. Since the cylinder is a filter formed from an Al porous body, the cylinder is perfectly filled with water when immersed in water and the air discharged from the conduit 4 is diffused in the water within the cylinder. When the diffused air passes through the filter main body 6, said air is diffused from the numberless void parts of the Al porous body to generate numberless fine air bubbles and the amount of dissolved oxygen in water is enhanced.</p> |
