| DESCRIPTION: The Comox Sewage Treatment
Plant is a secondary wastewater treatment facility handling up
to 12, 000 m3/d of municipal sewage. The dissolved oxygen and
suspended solids concentrations in the plant's aerated channels
were monitored using automated field equipment. Information was
recorded every 10 minutes to a computer disk, storing a month's
worth of data between equipment installation and removal. The
information was used to determine actual aeration requirements,
mixing efficiencies, responses to hydraulic surges, and to estimate
future expansion needs. |
