Rielli Biological Pack Waste Water Treatment Plants

Upon interruption of the aerationprocess, this time precipitation starts in the same volume. During thisprocess, the waste water treated biologically is separated from the waste wateractive sludge. After separation, the treated water is discharged by waste waterdischarge pump. Liquid chlorine is injected on the discharge line or thetreated water is disinfected by UV rays. The treated water may be used as it isor it may be further treated for irrigation purpose.

During aeration process, thebacteria (active sludge) shall, by their biochemical action, break down theorganic substances, suspended and dissolved, which constitute pollution in thewaste water and eliminate them by oxidation. Oxygen and fully agitatedenvironment necessary for this purpose is supplied by blower.

In the Rielli active sludge process operating by principle of continuousinput / intermittent output, the aeration and precipitation operations areperformed in the same tank by interrupting the aeration process periodically.
