Abstract

It is an object of the invention to provide a optimized rational water treatment technique for chemically treating water to be treated. A representative water treatment apparatus is adapted for chemically treating water by using chemicals. In a water treatment apparatus, a disinfectant within a chemical cartridge dissolves out in water to be treated in a disinfecting chamber so that the water is disinfected. Further, a magnet is disposed within the chemical cartridge. The accommodated position of the magnet within the chemical cartridge is changed according to the remaining amount of the disinfectants. The magnetism of such magnet is detected by a magnetic sensor disposed on the outside of the chemical cartridge, so that information on consumption of the disinfectant can be detected.

Claims8

Dependent claims

A water treatment apparatus for treating water to be treated comprising:

a treatment tank body,
a chemical treatment region in which the water to be treated is chemically treated,
a flow passage through which the water flows in the chemical treatment region,
a chemical accommodation housing that is disposed on the flow passage and accommodates chemicals which dissolve out in the water flowing through the flow passage,
a magnet that is accommodated within the chemical accommodation housing and changes in accommodated position according to consumption of the chemicals within the chemical accommodation housing,
a magnetic sensor that is mounted on a periphery of the chemical accommodation housing and detects magnetism of the magnet, and
a chemical information output section that outputs chemical information on consumption of the chemicals based on the magnetism detected by the magnetic sensor.
