ABSTRACT:
A structure for treating water used in public water supplies for removing dissolved gases. The installation includes a closed outer tank for storage of water and a vented inner tank for water aeration contained at least partially within the outer tank. The inner tank includes a column of packing media for aerating the water which is delivered from the ground water source to a point above the column. A flow of air is delivered into the outer tank above the water level, and an air inlet causes air to flow into the inner tank and through the column in counter-current flow to the water. The air is then vented to the atmosphere.
