Effluent and sewage treatment plants

Hello everyone, can some one tell me how much total suspended solids(TSS) comesfrom Aeration tank after processing? and secondary clarifier inlet.

example:ETP Inlet parameters

Flow 100 m3/hr

BOD = 1000PPM

COD = 2000PPM

TSS = 2000PPM

Let me know the outlet parameters BOD,COD and TSSof after

1.After primary clarifier

Types of biological systems

2.After activated sludge process( MLSS 3500 PPM)

3.After extended aeration process(MLSS 3500 PPM)

4.After MBBRaeration process(MLSS 6000 PPM)

5.After SAFFaeration process(MLSS 6000 PPM)

6.After SBR aeration process(MLSS 8000 PPM)

7.After MBR aeration process(MLSS 12000 PPM)

Please let know the answers its so very important to know

Regards

1. Hello What it is necessary to notice to go more quickly it is the difference of the organic mass between the entry and the end of the treatment carried out by a sewage treatment plant. The abatement is hardly 5% and still it is necessary to deduct the proportion from grease separated by the vat from degreasing. By having in spirit this data, one seeks where the abatement could well take place. The biological process of activated sludge should not function well or there does not exist. Some parameters come to reinforce my position: the quantity of mud at the end of the treatment (95%), the mechanism of mixing makes enter of oxygen (02) in the middle of the effluent, the oxidant more strongly, the time of completely insufficient transit to allow any work by the micro organizations, the presence of micro pollutant chemical contained in these effluents which kill 70% of the total colony count and handicap the 30% of survivor. Actually, in 'biological' term, ventilation only makes it possible to avoid a too strong methanisation of the 'effluent' to which the Organic matter is close to the putrefaction, which would explode the tank.
