Different manufacturers use different calculations, depending on their tank design, to set their recommended tolerances. The most important thing to remember is that you must always round up in size, and never down, and you must always use your own common sense.
How tall are chemical scrubbers?
The chemicals oxidize hydrogen sulfide and other odorous compounds producing innocuous byproducts.

Consider the following: 1 Locate the plant downwind of residences and other concerned neighbors. 2 Keep some buffer between residences and the nearest plant facility (say 500 ft.). 3 Build odorous facilities farthest from residences (i.e. headworks). 4 Cover and/or house the odor causing facilities, provide necessary ventilation and air scrubbing.
Is membrane bioreactor better than activated sludge?
For example, membrane bioreactors (MBR), by virtue of their smaller footprint, may be a better treatment process than conventional activated sludge. In small size plants, with MBRs, it may be possible to eliminate primary clarifiers, which often generate more odors than other processes at the plant.
