SUMMARY OF KEY WASTEWATER MATH FORMULAS
4. Sludge Density = ( 100 ) Index (SDI) SVI 5. Sludge to Waste, = ( Secondary SS, lbs ) - Effluent SS, lbs/day lbs/day ( MCRT, days ) 6. Sludge Age, Days = ( Aeration Tank TSS, lbs ) (Refer to MCRT ) ( Primary Clarifer Effluent TSS, lbs/day ) 7. Return Sludge = ( Aerator Flow, MGD ) x ( Settable Solids, % ) Rat e, MGD 8.
SBR PROCESS FOR WASTEWATER TREATMENT
activated sludge settles. •The activated sludge settles as a flocculent mass, forming a interface with the clear supernatant. •Usually this is the critical part of the cycle, because if the solids do not settle rapidly, some sludge can be drawn off during the subsequent decant phase and thereby degrade the effluent quality.
