Production of potable delicious water with the power of ozone and biological activated carbon

Advanced Water treatment is a water purification method. Through this water treatment the strong oxidizing power of ozone and the adsorption/decomposition effect of biological activated carbon produce potable delicious water.
The musty odor substance, which causes bad taste in water, is broken apart by the action of ozone, absorbed by activated carbon and decomposed by microorganisms bred in the activated carbon.
This collaborated action enables production of delicious water by eliminating the odor substance.
