In conjunction with the Ontario Ministry of Environment, NSFI completed testing the AquaO2 denitrification unit's capabilities. The results are published in NSFI's June 1994 report entitled research study, AquaO2 Aerobic Sewage Treatment System with Denitrification. The executive summary of this report states:
"...The unit was able to achieve significant denitrification resulting in effluent nitrate levels consistently less than 4 mg/l (overall mean 4.5 mg/l), while generally maintaining CBOD, levels below 30 mg/l. Influent tkn levels averaged approximately 40 mg/l, while effluent tkn plus nitrate-nitrogen concentrations averaged below 3 mg/l. In limited sampling, effluent nitrite levels were generally non-detectable and some removal of dissolved phosphate species was observed through the overall unit."
Maintenance
Weekly inspection suggestion list
An explicit Operation and Maintenance Manual is supplied.
By-products of the process are water, CO2, and a residue of inert materials such as coffee grounds, etc. This materials will accumulate over a period of time, and removal by a septic tank hauler once every 2-3 years may be required
The Mini-Plant series (Sequencing Batch Reactor-SBR) treats wastewater flows from 500 to 5,000 gallons per day.
The Maxi-Plant series (Sequencing Batch Reactor-SBR) treats wastewater flows from 5000 to 100,000 gal per day.
