Abstract
A water purifying apparatus has feeding device for feeding water under pressure; a bacteria culturing tank; and air supply device for feeding air to the bacteria culturing tank by inducing air by utilizing fluid energy of circulating water; and an air flow detector provided on an air suction duct of the air supply means. A filter provided upstream of the feeding means for feeding water under pressure has the capability of preventing moss from growing in a water tank and sterilizing water. An ultraviolet lamp for sterilizing the water in a water tank is provided in a circulating duct. A carrier for fixing bacteria which grows aerobic and anaerobic bacteria is composed of a basic mineral material.
