With increasingly stringent environmental standards, black and odorous sediments in lakes, siltation in farm ponds, and industrial sludge from chemical plant sedimentation tanks and oil tank treatment ponds are becoming long-standing global challenges. Traditional methods are not only inefficient but also suffer from high safety risks, high costs, and difficulties in manual management.
YG’s dredging robot is designed for these complex scenarios—from natural lakes to fishponds, farm ponds, and even chemical plant sludge ponds and oil tank bottom sediments, it enables unmanned, safe, and efficient intelligent dredging.

Why choose YG Dredging Robot? —Effective for everything from urban lakes to chemical plant sludge ponds
① Visualized Operation System — Lakes and chemical plants both require “visible safety”
The YG dredging robot is equipped with an underwater high-definition camera and a real-time video monitoring system. In lake dredging and pond remediation, it clearly shows the thickness of sludge; in chemical plant sedimentation tanks and oil tank treatment pools, it further prevents accidental contact with pipelines, equipment, or hardened sediment.
📌 Lake/Pond Pain Points Solved:
- Inaccurate depth, inability to confirm dredging effectiveness
- Turbid wastewater, extremely unsafe for manual entry
📌 Chemical Plant/Oil Tank Pain Points Solved:
- High concentration of industrial sludge, poor visibility of the tank bottom
- Traditional manual entry into oil tanks is extremely dangerous, easily leading to poisoning or suffocation risks
Real-time visualization makes the entire dredging process completely transparent, safe, and controllable.
② Explosion-proof Motor + Fully Enclosed Electrical Control – Designed Specifically for Chemical Environments
YG’s underwater dredging robot utilizes an explosion-proof motor and a fully enclosed, corrosion-resistant electrical control module, enabling stable operation in corrosive liquids, water-oil mixtures, and high-concentration sludge environments.
📌 Suitable Scenarios:
- Chemical plant sedimentation tanks
- Oil storage tank bottom sludge pools
- Paper mill sludge treatment pools
- Electroplating plant wastewater sedimentation tanks
📌 Addresses Customer Pain Points:
- Traditional equipment shuts down upon water or sludge ingress.
- Highly corrosive chemical pools result in short lifespans for ordinary machines.
- The high-risk environment inside chemical tanks prevents human access.
YG equipment is specifically designed for harsh conditions, making it the ideal dredging robot for the chemical industry.
③ Crawler Dredging Robot – Stable on the lake bottom, even more stable in chemical pools
Utilizing a tracked underwater chassis (crawler dredging robot), it can:
- Stablely move on silt, oil, and underwater sediment
- Protect from corrosion and rust
- Equal pressure design prevents deep sinking in soft mud areas
📌 Advantages for lakes/ponds:
- Can enter shallow water areas, accumulation areas, and vegetated areas
- Can handle black, smelly silt and decaying ecosystems
📌 Advantages for chemical plants/oil tanks:
- Can carry high-viscosity sludge
- Unaffected by oil, non-slip, non-drifting
- Can enter the pool without large lifting equipment
④ Fully Remote-Controlled Robotic Dredge – Avoids human entry into hazardous areas
The YG robotic dredge can be remotely controlled from the shore, outside the tank, or in the control room, without requiring personnel to come into contact with hazardous liquids.
📌 Advantages for Lakes/Ponds:
- Saves labor
- Avoids the risks of working in water
📌 Advantages for Chemical Plants/Oil Tanks:
- Avoids toxic gases
- Avoids the risk of suffocation in confined spaces
- More suitable for high-risk work scenarios
Super-powerful sludge suction system: Handles lake sludge and can also process high-viscosity oil sludge from chemical plants
YG’s sludge pump system features a high-lift, high-flow-rate, anti-clogging structure:
- Flow rate: 60–150 m³/h
- Head: 15–35 m
- Can handle particles, fibers, oil sludge, and chemical sediments
📌 Lake dredging: Black and odorous sludge, algae deposits, large amounts of organic matter
📌 Chemical tanks: High-viscosity oil sludge, metal sludge, corrosive sludge
Truly achieving “one machine for multiple uses,” suitable for municipal environmental protection, agricultural aquaculture, industrial wastewater treatment plants, etc.

South Africa Case Study: Dual Application of Lake Remediation and Industrial Sludge Pond
In 2025, a South African client purchased a YG crawler dredging robot for two scenarios:
① Private Lake Remediation
- Long-term accumulation of black, foul-smelling sludge
- Water quality deterioration and foul odor
- Boat-type equipment could not access shallow water areas
The YG robot could clean 40–60 m³ per day, completing the main area in three days, resulting in significant water quality improvement.
② Industrial Sedimentation Tank Cleaning
The client’s factory had two chemical sedimentation tanks filled with a mixture of oil and sludge, making manual access impossible.
The YG dredging robot, through its explosion-proof motor and visual monitoring, achieved:
- Unmanned dredging
- Smooth extraction of sticky oily sludge
- Dispersal and removal of hardened sedimentary lumps
- No production shutdown required throughout the process
The client’s evaluation was very clear:
“One device solved the problems of both the lake and the chemical plant, far cheaper than hiring an external dredging team.”
