The
Whitewater Combo model is a single unit system consisting of:
- Trash Tank
- Whitewater STP
- Pump Chamber
Bonded together
So when the Unit is placed into the excavation there are only
two hook-up's, - inlet & outlet.
The
Combo Models are available for Models:
DF50FF,
DF60FF & DF75FF

SOME FACTS
& FIGURES
Service/Maintenance
The inspection service to be performed by
a Registered Onsite Wastewate Practitioner (ROWP) in B.C.
Service is simplicity itself
Cleaning of intake filter of the Air Pump
is the only regular service to the TYPE2 Systems.
There are no submerged sewage pumps, no filters, and no moving
parts inside the Whitewater Unit to be removed, replaced, or cleaned.
Solids in Suspension Removal
Ask your Maintenance Provider to check for
the need to have the tank's contents removed.
WHITEWATER
SEWAGE TREATMENT PROCESS METHOD
The Whitewater Sewage Treatment Plant utilizes activated
sludge process, with extended aeration. Extended Aeration Process
has atmospheric air under pressure being introduced by linear
or rotary vane compressor into the Reactor Chamber (also known
as the aeration chamber).
The Reactor Chamber is the first chamber
that the crude sewage enters in the Whitewater Plant.
The arrangement of the air lines inside
the Reactor Chamber, causes the influent sewage and the returned
activated sludge to be constantly mixed together into what is
then called the mixed liquor.
Solids are not permitted to settle
in the digestion chamber.
The oxygen in the atmospheric air being released into the mixed
liquor activates micro-organisms known as aerobes.
The aerobes are excited into the absorption
and digestion process by the infused oxygen, and the product of
their digestion is CO2 and water. This extended aeration process
is constant, 24 hours a day.
The beneficial results of this extended
aeration process is mainly two fold:
- One is that there are no hydrogen sulfide
or methane gases produced.
- The other is that the efficiency of
the Aerobic Absorption Process is accelerated and enhanced,
resulting in lower BOD5 and SS levels, while maintaining high
DO levels.
LARGER
FLOW RATES
There are Whitewater Systems available
for flows greater than 22,730 litres (5,000 imp. gals.) per day
. Contact Canwest for details.
WASTEWATER TREATMENT SYSTEMS
The Whitewater System was approved by the
Ministry of Health, Public Health Protection Branch
in 1994. Canwest Tanks began marketing the Whitewater System throughout
BC in 1995 and
manufacturing in 1996.
Canwest has sold and manufactured more than 5,000 units for B.C.
The Ministry of Health, Sewage
Regulation lists three (3) types
of installation approved for disposal of domestic waste:
TYPE 1 System
Is a conventional Septic Tank &
Dispersal Field system.
The Sewerage Regulation outlines the setbacks, ground and soil
conditions that determines whether a conventional septic tank
& dispersal field can be used.
TYPE 2 System
A Whitewater Package Sewage Treatment
Plant is installed as the primary receptacle & aerobic treatment
unit for domestic wastewater.
The system (tanks) generally consist of:
Trash Tank, Optional but strongly recommended,.
The Whitewater Sewage Treatment Plant, c/w Aeration Blower &
the aeration assembly installed into unit.
Discharge Pump package, if other than gravity flow to field.
A disposal field will still be required, however, as mentioned
above, may be greatly reduced.
TYPE 3 System
The WHITEWATER TYPE 3 System is an extension of the Whitewater
System, and is used in applications where.the effluent quality
must meet specific criteria
A TYPE3 system must be designed by a professional (P.Eng.) with
experience in environmental matters.
The
Onsite Sewerage Regulations specifies the acceptable effluent
quality for a TYPE3 System as being:
- BOD5 = 10 mg/l
- TSS = 10 mg/l
- Nitrate = 10 mg/l
- Fecal Coliform = 400 CFU/100ml
The equipment required
for this treatment method generally consists of a Trash / Pre-Settling
Tank, Whitewater Sewage Treatment Unit, Clarifier / Filtration
Unit, UV Disinfection Unit, and if required, Discharge Pump
Package.
Please note that design criteria may vary as influent strength
and disposal method have a bearing on the treatment process.
