33、solids(SS)and volatile suspended solids(VSS)are the most useful.SS and BOD(biochemical oxygen demand)are used as measures of wastewater strength and process performance.VSS can be an indicator of the organic content of raw wastes and can also provide a measure of the active microbial population in b
