Each of the following is one of the five stages in using the HOOT Aerobic Treatment System for sewage disposal, except:

Digestion
Clarifying
Chlorinating
Aeration

Explanation

Answer: A - The HOOT Aerobic Treatment System does not incorporate a stage in which waste is digested. Other systems with anaerobic components incorporate digestion as one of the treatment stages. It operates aerobically in stages that pretreat, aerate, clarify, chlorinate, and finally store the effluent prior to its post-treatment discharge to its final use.
