Plant/Process Description:
Primary Treatment: Consists of mechanical bar
screen, pista degritter, primary sedimentation,
flow equilization basins and sludge fermenters
to supplement the phosphorous removal process.
The existing digesters from the old activated
sludge process are now used for sludge
thickening and to supplement alkalinity for
process control.
Secondary and Tertiary Treatment:
Consists of a biological phosphorous and
nitrogen nutrient activated sludge process
(based on the modified UCT process combined with
a primary sludge fermentation system), secondary
clarification with activated sludge return and
wasting and shallow sand bed filters with
automatic backwash.
Disinfection Method: Consists of
chlorination and dechlorination.
Sludge Conditioning and Composting:
Consists of the primary sludge being fermented
and then treated by anaerobic digesters. The
methane gas produced by the digesters is used
for plant building and sludge process heating.
Wasted bioreactor and secondary activated sludge
is gravity thickened, belt settled, belt press
dewatered and then composted on our compost site
at the cities landfill site.
Composting is by
static pile aeration method, which produces a
high-grade quality soil conditioner. This
conditioner / fertilizing product is recycled to
City Parks, landscapers, the public and farmers
for agriculture use.
Effluent Irrigation System: The treated
effluent can be stored in two emergency on-site
36,000 m3 storage basins for re-use. Irrigating
with the effluent is done by a on-site pumping
facility direct drawing from the chlorine
contact tanks to the local Golf Course and City
Parks over a six month irrigation period.
River Outfall: Treated effluent is
discharged through an under water diffuser
system into the Okanagan river channel adjacent
to the plant site.
Plant Staffing: Presently the plant is
staffed by seven certified operators, a
millwright, an electrician and a laboratory
technician.
Odor Control Systems: The odors are
controlled by two types of systems. Odors are
removed from the concrete covered fermenters and
the fabric covered primary tanks by a positive
displacement blower discharging into the
bioreactor. Two main lift stations, headworks,
digester hoppers and the degrit building have
odors removed through carbon canister systems.
Process Control: The system is Windows
NT software computer controlled through Modicon
programmable logic controllers. The plant and
lift station alarms are connected by a telephone
modem system to the main Fire Hall. The plant
has the capability of chemical addition of alum
or ferric chloride and sodium acetate if
required for phosphorous removal.
