Septic Tank Cleaner Truck

The working principle of the sewage suction truck:

Due to the continuous immersion of the fecal suction hose on the liquid surface, 

the air inside the fecal tank becomes thinner and thinner as it cannot be 

replenished. As a result, the pressure inside the tank is lower than atmospheric 

pressure, and the fecal liquid enters the tank through the fecal suction hose under

 atmospheric pressure. Or due to the proximity of the siphon tube to the bottom 

of the tank, when air is continuously discharged into the manure tank, it is 

compressed because there is no way out, causing the pressure inside the tank 

to be higher than atmospheric pressure. The manure liquid is discharged outside 

the tank through the siphon tube and suction hose under the action of compressed 

air.

The production workshop process is shown below:

1: Clear division of labor for assembly line operations (each process is self inspected and qualified by a dedicated 

person before entering the next process)!

2: All workshop welders have welding certificates (welding technicians have more than 10 years of work experience)!

3: Quality department (semi-finished product inspection, testing, pre spray testing, pre shipment testing, trial run 

inspection, qualified before leaving the factory)!

4: Using manganese carbon steel plate raw materials and standard well-known brand accessories, fully automatic 

welding equipment (single-sided welding double-sided forming, resistant to solid and pressure without sand)

Eye, false welding and leakage situation)!

5: Adopting advanced sandblasting and spray coating technology (sandblasting: can remove all surface rust and other 

dirt, oxide layer, effectively improve the adhesion between the tank and the spray coating)

Focus and anti-corrosion ability. Spraying can make the tank display a uniform and smooth natural color, making the 

appearance more beautiful and visually appealing!

Frequently Asked Questions (FAQ): Foton 2 Cubic Cleaning & Suction Truck

1. Q: What are the primary functions of this truck?
A: This truck is a versatile 4-in-1 unit designed for high-pressure flushing, pipeline and sewer dredging, powerful vacuum suction of liquids/sludge, and controlled reverse discharge of collected waste into a designated disposal point.

2. Q: Where is this 2-cubic-meter model most effectively used?
A: Its compact size and full functionality make it ideal for urban sanitation maintenance, cleaning restaurant district grease traps, servicing residential and commercial septic systems, maintaining drains in industrial parks, and cleaning municipal streets and marketplaces where larger trucks cannot easily maneuver.

3. Q: How does the high-pressure cleaning system work, and what is its main benefit?
A: It uses a high-pressure plunger pump to pressurize water, which is then expelled through a specialized gun and nozzle at high velocity. This high-pressure, low-flow technology provides intense impact to break up blockages and stubborn grime with superior cleaning power and significant water savings compared to low-pressure, high-volume methods.

4. Q: What kind of waste materials can the vacuum system handle?
A: The powerful vacuum pump and system are engineered to handle a wide range of materials, including watery sewage, thick slurry, sludge, sand, and small solid debris commonly found in drains, septic tanks, and settling ponds.

5. Q: Is a special driver's license required to operate this vehicle?
A: Licensing requirements depend on the local regulations in the country of operation. Typically, due to its size and weight on a light truck chassis, a standard commercial driver's license is sufficient, unlike larger trucks which may require a heavy vehicle license. Always verify with your local transport authorities.

6. Q: What happens if a severe blockage cannot be cleared by water jet alone?
A: The truck's core advantage is the immediate combination of functions. The high-pressure jet loosens and breaks up the blockage, while the vacuum system simultaneously extracts the dislodged material. This continuous "clean-and-remove" action is highly effective against even severe, compacted blockages that manual methods struggle with.

7. Q: What is the water source for the high-pressure cleaning function?
A: The truck is equipped with an onboard water tank (capacity varies by configuration). It can be refilled from any standard water source such as a hydrant or water truck on-site. This self-contained system allows for operation in areas without direct water access.

8. Q: What is the typical "fill-up and discharge" cycle time for the 2m³ tank?
A: Cycle time depends on the material's viscosity and the suction hose length. Generally, suctioning 2 cubic meters of watery sewage can take approximately 3-5 minutes, while thicker sludge may take longer. The hydraulic self-dumping function allows for rapid discharge in under 2 minutes.

9. Q: Are there any specific permits needed to transport and dispose of the collected waste?
A: Yes. The transportation and disposal of collected waste are typically subject to local environmental and sanitation regulations. Operators are responsible for obtaining necessary permits and disposing of waste at licensed treatment facilities. We recommend consulting with local authorities for specific compliance requirements.

10. Q: What kind of after-sales support is available, and are parts readily accessible?
A: We provide comprehensive support including operator training, detailed manuals, and a dedicated service hotline. Given the widespread availability of the Foton chassis and our standardized component inventory, genuine replacement parts are readily accessible through our global distributor network to ensure minimal downtime.
