This article shows the Veolia Sewage Cart. Veolia is a company specializing in sewage treatment solutions in Australia. As can be seen from the picture, Veolia Sewage Suck suction pipe has a long pipe diameter and a thick nozzle. At the same time, the suction truck has a large suction force and can directly suck up the grass and mud on the mud. Workers can use the operating panel to control the direction and suction of large suction pipes. In this way, not only the personal safety of the workers is guaranteed, but also the effect of the sewage suction truck is better. In addition to the large suction pipes, Veolia Sewage Sewage Pumps are equipped with tiny suction pipes, which are mainly used to handle some tiny mud. Manual positioning of the fine suction pipe allows precise positioning. The common sewage suction truck mainly dumps the sludge from the rear of the tank, while the Veolia sewage suction truck adopts the way of dumping the sludge on the side, which will greatly reduce the time for unloading the sludge. After years of development, the sewage suction trucks in China have gradually narrowed their gaps with foreign products in the effect of sewage suction. However, in terms of intelligence and garbage unloading, there is still a need to learn from overseas sewage suction trucks.

Sewage suction trucks are our common sanitation vehicles and can be used to collect liquid substances such as manure, mud, and crude oil. At present, most of the sewage suction trucks use vacuum pumps, which have a large suction force and a long suction range. They are particularly suitable for the suction, shipment, and discharge of sludge in sewers, and in particular, they can suck sewer mud, silt, and gravel. Large objects such as bricks.
