LWT CORPORATE MISSION: LWT provides value to our
clients by using our experience and expertise to incorporate technology to provide
innovative, quality systems and component equipment for the dredging, removal, agitation,
transfer or land application of solids bearing liquids.
LWT Inc. manufactures the PIT HOG line of
Hydraulic horizontal auger head dredges, lagoon pumpers and pumping systems for the
handling of nearly all semi-liquid or liquid wastes.
LWT designs and provides complete systems for land
application of sludges, bio solids and liquid livestock manure by direct sub-surface
injection including tool bars, hose reels and agitators.
LWT specializes in custom design/build
electronically controlled, hydraulically powered systems for remote operation with
specific remedial needs (including Super fund). This includes rail tank car agitators,
submersible robotic crawlers, and submersible chopper pumps for digester cleaning systems.
In addition to these custom applications, we also design a number of control systems,
including hand held, automated, electronic and radio remote controlled interfaces.
LWT provides specialized sub-contract dredging and land
application services for municipal WWTP sludges, water plant lime, food processing bio
solids, industrial process residuals silt and sand and other types of lagoon slurries.

LWT Inc., Liquid Waste Technology, manufactures PIT HOG
Series PH7MAU horizontal dredges for effective dredging and performance. LWT
engineered this unit with quality construction and components for long term reliability
and dependable ease of operation. Understanding the component parts of these units will
lead to an appreciation of the potential of the machine.

BOTTOM SENSE™ Use LWT's BOTTOM SENSE™
system to protect pond bottoms and liners. Switch on BOTTOM SENSE™, and the
sensing system will automatically raise the auger head when the bottom is contacted and
lower the head when it senses that the bottom is not present. This allows for more
accurate control in following the bottom contours of the lagoon or pit.
SOLIDS SENSE™ Incorporation of LWT's S0LIDS
SENSE™ solids control dredging system will automatically work to maintain
delivery of a constant solids density. Set the desired solids density level and the
control system will continually respond to maintain that level. The SOLIDS SENSE™
control system reacts quickly and virtually eliminates the need for hands on operator
control while dredging. This enables LWT systems to manage your solids production
to a level of accuracy never before possible
RADIO REMOTE SENSE™ LWT has
designed this system to allow complete remote control of the dredging operation with a
portable radio system. The hand held control panel may be operated at A distance of at
least 2,000 feet from the dredging unit, with three revolving lights on board the dredge
indicating when the auger, pump, and travel motors are running. This controls the
functions of speed and direction for the following:
Slurry pump
Auger
Unit travel
The RADIO REMOTE SENSE also controls:
Power on/off
Dredging depth
The hand held control panel may be operated at distance of at
least 2,000 feet from the dredging unit. For ease in visual checks, even at a distance, LWT
PIT HOG dredges are equipped with three separate revolving lights indicating when the
auger, pump, and travel motors are running. As LWT integrates electronic control
systems on its PIT HOG equipment, this control system may be used to drive either electric
or engine power plants as well
AUTO SENSE™ Cable stops are set on the
traverse cable at the limits of the area to be dredged. When the dredge contacts the
forward stop, the unit will automatically stop forward travel, raise the auger, slow the
slurry pump speed, and reverse at a high rate of travel until it makes contact with the
rear stop. The dredge will then lower the auger head and shut down (or alternatively wait
for a command to go forward).
LATERAL SENSE™ When the project application
calls for automated lateral movement LWT can incorporate and control this
function by installing an on board radio system.
COMBINATION SENSE FEATURES FOR TOTAL REMOTE CONTROL BY
RADIO Combine these features for efficient automated dredging, while minimizing
labor. The dredge travels forward with the SOLIDS SENSE™ system controlling
production and travel across the pond, while automatically maximizing solids. BOTTOM
SENSE™ protects the pond bottom and follows pond contours. LATERAL SENSE™ is
combined with AUTO SENSE™ and the other systems described above for complete control,
cable free, automation. Utilizing these features cuts the labor requirement and the hands
on intensity of any project while optimizing production levels.
