The continuous circulation of sewage more than these growths enables the microbes to soak up the dissolved organics, Therefore reducing the biochemical oxygen demand (BOD) of the sewage. Air circulating upward throughout the Areas Among the many stones supplies enough oxygen for that metabolic processes.
