How tall are chemical scrubbers?
The chemicals oxidize hydrogen sulfide and other odorous compounds producing innocuous byproducts. If the owners prefer chemical scrubbers, they usually will be tall (10 to 15 ft.), but can be hidden behind an architecturally designed wall facing the neighbors. In exceptional cases, the wall can have a nice mural painted on it to enhance appearance. [See Figure 1]
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.
Should structures be off-set?
