The special features of the water treatment apparatus in the present
invention are that a tank fitted with a raw water inlet and a treated
water outlet on the upper part, has within said tank an upper chamber and
lower chamber which divide said tank into two sections, upper and lower,
and is fitted with a separating wall which can be raised and lowered to
adjust the water level in said upper and lower chamber, the upper chamber
above said separating wall and the lower chamber below said separating
wall both being filled with water. By use of this apparatus, a novel water
treatment apparatus is provided which can be extremely easily assembled
into a water treatment facility.
