A serious odour is being emitted from the site of a trickling filter. Discuss the reasons for this odour and how this reflects a problem with the filter efficiency. What corrective measures can be taken to control this nuisance?

Expert Solution
A trickling filter is a system that used for wastewater treatment. There would be many abnormal situations when we carry out this process. One of them is odor complaints. Odor is released when the air movement resumes upward or downward. Many times we cannot control the odor emission from the filter. It affect the efficiency of the system. The system should provide the normal environmental conditions when proceeding with the process. The abnormal odor cause environment stress. The offsite odor should be below the detection level.
Inorder to reduce odor emission there are several methods used. Odor dispersion modelling is essential when the filter is built. The calculation can be 40000 cfm scrubber exhaust with a 100 D/T odor level would require 50 foot high stack.
There are other methods. chemical addition, periodic cleaning etc.. help to reduce odor. Chemicals like oxidizers(ozone), bactericides (chlorine) etc.. can be used

Design a low rate trickling filter for secondary treatment of
sewage generated from 10,000 persons with rate of water supply 170
liters per capita per day. The BOD5 after primary treatment is 110
mg/L and BOD5 of final effluent should be 20 mg/L. Consider the
following equation, where C = 5.358.
(St/So)=(1)/(1+C((D^0.67)/(QL^0.5))
Now, design a high rate trickling filter for the data given
above except effluent BOD5 is 40 mg/l since polishing treatment is
provided after high rate trickling filter....

Primary sludge containing trickling filter sludge is gravity
thickened in a circular tank with a diameter of 12 ft, and side
water depth of 10.0 ft. The applied sludge is 2600 gpd with 4.5 %
solids (by wt.) and the thickened sludge withdrawn is 1300 gpd at
7.5 % solids (by wt.). The sludge blanket in the tank is 3.0 ft
deep. For odour control, and to enhance thickening, 45,000 gpd of
treated wastewater is pumped to the tank along...
