Hello Dear Mr. Mallikarjuna, ...

Hello Dear Mr. Mallikarjuna, how have you been? I think that are some important points for you to know how much TSS come out of the aeration Tank, as folow: - The Organic Load (BOD): the solids generation depends of the Organig Mather that inflow in the aeration basin. - Sludge Recicling: how much sludge are recicled into the aeration basin? - Biological activitie and conditions: How are the biological conditions of the effluent? Is it good for biodegradation? (Temperature, Yeld, Biological kinetics, aeration type, all those factor must afect the TSS production) Look in the section 8-3 of Metcalf and Eddy for more information. Some literatures say that the TSS in the Aeration basin must be between 2500 to 4500 mg/l for activated sludge. But if you are using MBR, this can be rised to 8-12 tousand mg/l (or even more!). Well, this is will depend on the factoros cited above. Regards!
