Where To Buy A Vacuum Truck
The cost of an industrial vacuum truck for use at a wastewater treatment plant is generally too much
for the average municipality’s budget. However, due to the versatility of the industrial equipment, a
township or city can get a tailored system designed to multi-task and spread the cost out amongst the
different departments for which it is used. A liquid vacuum truck (LVT) can be used for transporting
sludge and cleaning catch basins and sludge tanks. It can also be used for emergency spills for the fire
and rescue department as long as it’s built to the right standards and has the proper certifications.
Working together between departments is the key. IT’s funny because most wastewater treatment
plant managers think of sewer department vehicles when they hear the words “vacuum truck”. These
combination machines are far and away the most common vacuum systems used by municipalities
today. They have high-pressure water to blast through obstructions in pipes and vacuum suction
to remove debris, thereby making them ideal for sewer applications. However, industrial vacuum
systems can play a vital role in wastewater treatment sludge applications, too! Both industrial vacuum
loaders and industrial liquid trucks perform many tasks beyond the standard combination machine’s
capabilities.
Aside from specialty fittings and adaptations for individual and unique circumstances, the vacuum
source is truly the only difference between municipal and industrial vacuum trucks. Most combination
machines use fans known as centrifugal compressors that generate high air flows for vacuum. Industrial
vacuum loaders and liquid trucks use vane pumps, also called positive displacement pumps, which
have lower air flows but create high vacuum levels. This is ideal for deep pulls and heavy sludge.
Municipalities can use the increased vacuum power to their advantage!
One city used a liquid vacuum truck to transfer sludge to drying beds. The tank would pressurize,
the valve would open and a special fan nozzle sprayed the material ensuring that the thorough and
rapid sludge transfer through the discharge valve. Another used an industrial vacuum truck to remove
sludge around clay aeration pipes. It vacuumed the material over 210 feet after a 60 foot lift. With
an on-board crane and removable cyclone, it was parked with the cyclone suspended over the bed of
a dump truck. Slide gate valves that alternately closed and opened allowed the cyclone to discharge
material continuously. This gave the hose-handler the chance to vacuum uninterrupted. Loading
and unloading simultaneously saved so much time compared to the standard processes that require
shutdown during dumping. One more example was a case where, over time, methane gas from sludge
deteriorated infrastructure pipes in a water treatment facility. To repair the damaged pipes, the sludge
was temporarily re-routed through the truck at 1200 - 1500 gallons per minute by a liquid vacuum truck.
In this instance, it served as a temporary bypass system.
A little interdepartmental cooperation can go a long way in allowing municipalities to find that industrial
vacuum systems can be an innovative and cost-effective solution to an unlimited array of municipal
issues.
