what is Sludge volume index | SVI kise kahte hai | Hindi | @ETPKnowledgeJunction

Sludge volume index is the standard measure of the physical characteristics of activated sludge processes. It is defined as 'the volume (in mL) occupied by 1 gram of activated sludge after settling the aerated liquid for 30 minutes'. Significance : •Its represent the degree of concentration of the sludge in the system and hence Decide the rate of recycle of sludge require to maintain the desired MLLS (mixed liquor suspended solids). •SVI gives a more accurate picture of the sludge settling characteristics than settleability or MLSS alone. •SVI used to indicate the physical state of sludge produced in a biological aeration system. SVI (mL/g) = settled sludge volume (mL/L) X 1000/mixed liqour suspended solids(MLSS)(mg/L) Range: 50 to 150mL/gm (its indicate good settling sludge). #etpknowledgejunction #science_classes #sludge_volume_index #chemical_oxygen_demand #biochemical_oxygen_demand #Importance_of_BOD_and_COD #Wastewater_treatment #waste_water_treatment #activated_sludge_process #sanjeet_rawat #microorganisms_and_BOD #food_and_mass_ratio #nurtureflora #wastemanagement #wastewater ________________________________________________ Watch the full videos and keep supporting the channel.
