High svi wastewater
WebA high SVI (>150 mL/g) indicates bulking conditions, whereas an SVI below 70 mL/g indicates the predominance of pin (small) floc. Based on the relationship between floc-forming and filamentous bacteria, three types of flocs are observed in activated sludge: normal flocs, pin-point flocs, and filamentous bulking. WebIn covered aeration basins, foam can accumulate to exceed the available hydraulic head for gravity flow of wastewater through the basin. Process control can be compromised if a significant fraction of plant's solids inventory is present in the non-circulating foam. ...
