Solutions addressing the classic
problems of ground impermeability, high water table, and other
poor soil conditions...
ExtremeSTP models USTP500, USTP750, USTP900,
USTP1500, and USTP3000 sewage treatment plants are built to operate
below ground in a cold environment without need of a building
or other enclosure. Larger below ground models can be ordered
for specific projects.
A patented tank (U.S. Patent Number 422,675 held
by Alaska Tank Systems) is used on the USTP models. The smaller
ATS tanks are built with 3/16-inch plate steel. Fittings have
a 1/4-inch wall thickness. As the tank size increases, 1/4-inch
plate is used for the top and bottom and eventually for the whole
tank. Each tank is designed and constructed for the intended use
and type of installation.
After welding, each tank is sprayed inside and outside
with a rust preventative coating. After a curing and drying period,
each tank is coated with a two-part epoxy product that is formulated
to resist the corrosive effects of wastewater. Then two inches
of Dow Blueboard rigid foam insulation is attached to the outside
of the tank to help retain heat and maintain bacterial activity
in all compartments.
Up to and including the Model USTP1500, the underground
systems are manufactured in a single, multi-compartment tank.
The first compartment pre-treats the sewage by retaining floating
and settling solids. USTPs have an intermediate treatment compartment
with a Zabel filter (Model 1800A on most models) to provide some
additional solids removal before the sewage enters the third compartment.
In the third or "aerobic treatment compartment,"
a Bio-Microbics FAST® (fixed activated sludge treatment) insert
aerobically (with oxygen) treats the wastewater. For those sites
where disinfection is needed, an optional UV (ultra-violet) light
or chlorination system disinfects the wastewater.
If needed, a fourth compartment provides effluent flow control.
Treated effluent is retained in this compartment until there is
a sufficient quantity to trigger discharge. Depending on site
requirements, discharge can be controlled by either an automatic
dosing siphon or an effluent pump. In the case of a siphon, the
water rises to a predetermined level, then an automatic dosing
siphon (with no moving parts) allows the water to discharge out
of the system at about 30 gpm (gallons per minute) for about one
minute. Even at -60oF, when warm water is discharged at this rate
and quantity it does not freeze at the point of discharge. Instead,
water flows away from the system before soaking into the natural
vegetative mat, into the ground, or freezing on top of the ground.
In any case, ice buildup at the point of discharge is minimized
or eliminated.

Model USTP500 Specifications
The USTP500 is a residential sewage treatment
plant for a 1 to 3-bedroom home on a well or piped water system
(regular-water-use home). It is rated for up to 500 gallons
of domestic sewage per day from 1 to 8 people.
Key Features:
-
Dimensions are 12'8"L x 5'2"W
x 6'3"H (not including the riser pipes, blower, etc.
that get mounted on top during field assembly)
-
Consists of one multi-compartment steel
tank with 4-inch risers for sludge and septage removal,
6-inch risers for the Zabel filter (standard equipment)
and UV system (optional), and a large-diameter riser on
which the blower mounts
-

Depending on usage, operating time can be
reduced by using the timer (standard equipment) to about
1 out of every 2 hours during the warmer months, cutting
electrical consumption by nearly one half
-
Options include: UV disinfection, automatic
dosing siphon, effluent pump system, heat tape, additional
insulation, and skid mounting for transport or seasonal
use
