Ozone Systems IN-SITU GROUNDWATER REMEDIATION (ISCO) |
|
Mobile groundwater system - turnkey package installed in 48' trailer for air/ozone sparging at 60 injection wells. The unique design minimized site work
to: 1) connection of sparge lines to distribute manifolds; and 2) installation of electric service - resulting in significantly lower project costs when
compared to a contractor "assembled-on-site" system. Interior photos (click to enlarge) show components of the system and PLC control that governs
the sequential cycle times of 12 air/ozone sparging manifolds.

Stationary groundwater remediation system with 24 lbs/day ozone - turnkey package installed in 20’ cargo container for air/ozone sparging at 80
injection wells. The 80 injection wells are connected to eight distribution manifolds located remotely from the equipment container and supplied by 1”
underground feeder lines. Each feeder line connects to the air/ozone supply system in the equipment container through electrically actuated ball
valves,
with sequential open/close function controlled by a PLC to provide user adjustable timing of pulsed sparging.

Since 1998, Ozonology
has been designing and
fabricating turnkey systems
for remediation of groundwater.
Working with a prospective
client’s engineers,
together we examine the
requirements of a site and,
drawing upon Ozonology’s
experience in equipment design,
conceptualize a system that
meets the specific requirements
of that site. Ozonology then
submits a drawing of the
envisioned system for review.
Following approval, a quotation
with detailed itemization of the
proposed equipment and fabrication
is submitted for consideration.
In the foregoing process of
system design, holding down
cost is a key element. To utilize
smaller size, thus lower cost
equipment, large complexes of
remediation wells are divided
into multiple groups of 5-10
wells each. One such group is
“on line”, then sequentially
followed by others for pulsed
air/ozone sparging. This is
equivalent to operating just a
small 5-10 well system.
A typical turnkey package
system consists of an ozone
generator, ozone generator
feed gas air dryer or oxygen
generator, recirculating water
chiller for 12 lbs/day and
above ozone generators,
rotary screw air compressor,
air/ozone sparging manifold
or groups of manifolds,
flow meters, air/ozone
flow rate control valves,
pressure regulators,
and PLC for integration of
system interlocks and monitors,
and user-programmable timing
of sparging duration.
The package system can be
built into a 20’ steel cargo
container for stationary
installation or a trailer
for mobility, or can be provided
as component assemblies to install
in a job site building. All systems
are fully tested before delivery
and ready for connection of
electrical service and sparge
well lines.
Ozonology does not provide any
below-grade apparatus, i.e. sparge
well components or sparge line tubing.
