Abstract
A continuous purification apparatus includes a mixer to mix contaminated water and purifying chemicals, a purifying tank to receive mixed matter from the mixer and in which inorganic and organic matter are separated to produce floating matter, sediment and purified liquid, a purified liquid piping system by which the supernatant in the tank is discharged, and a drain piping system by which the floating matter and sediment are discharged. An intermittent type purification apparatus includes a window mechanism provided in a side wall of the tank and a tub encompassing a lower peripheral portion of the tank.
