Sludge wasting rate
WebbQ s = sludge surplus (or excess) flow rate (m 3 /d) This equilibrium formula for settling tanks is mostly calculated for the initial flows in m3/h. This formula describes that the … Webb25 juni 2024 · You will need to increase the waste sludge rate. This will result in a slower rate of settling, which in turn will trap more of the solids suspended in the mixed liquor, leading to a clearer effluent. To reduce the index. You will need to do the inverse of the above, and reduce the waste rate. This results in a thicker sludge with heavier ...
