A vacuum truck is also known as vacuum tanker. It is comprised of a tank and a pump. The design of the pump is meant for sucking up the liquids, slurry and sludge. The main objective of these trucks is to transport the liquid materials to another location via road. The vacuum trucks transport the sewage materials to the disposal site or for treatment. Some of the most common materials that are transported are human excreta, slurries, industrial liquids and sewage sludge.

The configurations and design

The commercial vacuum trucks meant for collecting the fecal sludge generally have a volume of 10-55 m. Apart from that, there are many other small versions for some specialized applications.

  • Pumps– The pumps usually use a liquid ring pump or a sliding vane pump with a low volume so that some negative air pressure can be created. There is very less use of diaphragm mud pumps but the advantage of diaphragms is that it is cost-efficient and the design is simple. The disadvantage of these pumps the mechanical parts of this pump can easily come into contact with the sludge which doesn’t happen with the vacuum pumps.
  • The suction hoses– The suction houses on these trucks are 5 to 10 cm in the diameter and 7.6 cm while being normal. The lengths can depend on multiple factors which are quite related to the pressure losses and the lift. But it cannot be extended more than 50 m.
  • The final part– Emptying- A tanker is emptied by the gravity usually. There is a possible chance that the pressure in the vacuum truck can be forced up and out. Thus, it flushes out the sludge quickly.
