What is the difference between a sewage suction truck and a fecal suction truck?

Here is an introduction to the differences between sewage suction trucks and fecal suction trucks: The structure is the biggest difference between sewage suction trucks and fecal suction trucks, which also leads to significant differences in their uses. 1. Vacuum degree and suction force: Affected by the structure and shape of the tank, the vacuum degree and suction force of fecal suction trucks are not as strong as those of sewage suction trucks. 2. Capacity: Fecal suction trucks use the pressure difference of the vacuum pump for sewage discharge, which is limited by the position of the sewage outlet. Larger stones cannot be discharged, making them unsuitable for dredging work involving larger objects. 3. Sewage discharge effect: Sewage suction trucks adopt a hydraulic top-opening self-dumping sewage discharge structure, resulting in better sewage discharge efficiency and effect. 4. Domestic usage habits: Influenced by domestic usage habits, sewage suction trucks are more commonly used by users in the north, while fecal suction trucks are more commonly used by users in the south.

I often get asked about the difference between a vacuum sewer cleaner and a fecal suction truck. The key difference lies in what they handle. The fecal suction truck is mainly for dealing with feces, like cleaning septic tanks in rural areas or residential communities. It specializes in handling smelly and sticky fecal waste, with a smaller tank and simpler structure, making it easy to operate but only suitable for soft waste. On the other hand, the vacuum sewer cleaner is more versatile—it can handle various types of sewage, such as sewer sludge, industrial wastewater, and even kitchen waste. It has stronger suction power, a larger and more durable tank design, and a broader range of applications, often equipped with a filtration system to prevent clogging. I once witnessed a friend mistakenly use a fecal suction truck for industrial wastewater, which caused the tank to burst. This incident shows that choosing the wrong equipment not only reduces efficiency but can also lead to major failures, affecting environmental hygiene. So, depending on your needs: for everyday household use, a fecal suction truck is convenient, but for more complex cleaning tasks, a vacuum sewer cleaner is the more reliable choice.
