What happens with the degradation of substrates in activated sludge if you add a clarifier. The activated sludge retention time is 0.5 days and the sludge age is 2 days. Also, what if the sludge age is 4 days

1. A surveyor completes a levelling circuit from a known BM at point A (RL = 37.730 m). At the end of the survey, the surveyor finds out that the rod person moved the graduated staff before a BS value was taken at the third change point. The levels obtained are as follows:  

1.857 (RL = 37.567 m), (0.983, 0.354), 0.571, 1.011, 2.151, (1.124, x), 0.890, (0.543, 3.178), 3.808.  

1. Assuming that the misclosure for the level circuit is 0.000 m, find the probable value of the missing BS value x.   
2. Is the value of x in part (a) acceptable? Explain. (1 mark)

Book the levels, including the value of x calculated in part (a) using the HPC method and show all arithmetic checks. (1 mark
