Septic systems are vital structures, particularly in rural areas where sewage lines are not available, serving as temporary sewage holding structures located behind and below residential structures as well as commercial buildings. Because the septic system is only a temporary storage device, it eventually fills with solid waste and it is unusable unless it is emptied again. The job of removing the contents of a septic system tank is handled by the work of a vacuum truck equipped and sold as a septic truck for sale.
A vacuum truck is a mobile unit for collecting a wide variety of liquid and semi-liquid material such as sewage from septic systems. Aside from collection, it is also used to transport material to an intended destination either for treatment or disposal. In order to accomplish such work, a vacuum truck must be roadworthy and at the same time safely hold a large volume of liquid and travel through public highways. So the vacuum tanks must be mounted on a standard truck chassis.
As a hauler for liquid and semi-liquid material, a vacuum truck that has been purchased from a septic truck for sale dealer is equipped with components that allow it to do the job effectively and efficiently.
- Vacuum Pump – The vacuum pump is what gives the vacuum truck its identity. It is a mechanical device that is capable of generating massive negative pressure by rotating massive steel vanes that are driven by the truck’s Power Take Off or PTO. The vacuum pump is equipped with an exhaust port and an inlet port where negative pressure is generated by suctioning massive air volume through the inlet port.
- Suction Line – At the end of the vacuum unit’s inlet port is the suction line consisting of flexible rubber tubing that directs negative pressure toward the material to be removed. Strong negative pressure along with the narrow opening of the end allows the equipment to remove fluids and solids through the suction line.
- Holding Tank – The fluid and debris suctioned through the tip of the suction line goes straight through the hose into the holding tank to be securely stored for transportation until disposed at its intended destination. Some holding tanks have an agitator, which is a mechanical device that constantly keeps the mixture of solid and liquid mixed to prevent the solids from settling at the bottom of the tank.
- Fresh Water Tank – In addition to the holding tank, some vacuum trucks also include a fresh water tank. This provides a fresh source of water for various purposes such as agitating the solid debris in the septic tank or cleaning the septic tank after vacuuming has been completed.
- Pressure Pump – The fresh water tank is typically paired with a pressure pump that increases the pressure of the water leaving through the nozzle of the hose to give it power for cleaning tough dirt and grime.
The combined working capability of all these components allows for the safe handling of bio-hazardous and caustic liquids while limiting the exposure of workers to a minimum by automating the system and eliminating the need to handle the material directly.
The suction power generated by the vacuum pump is what allows the vacuum truck to quickly suction the contents of septic systems. Once the sewage is contained in the storage tank, it is delivered directly to a treatment plant for processing. At such a facility, the mixture will be treated with antibacterial agents before it is dried and the remaining solids processed to be used as fertilizer. All of this started out with the purchase of a good used vehicle from a septic truck for sale dealer – and a powerful vacuum truck has been equipped to handle the worst septic systems!
