Slurry treatment plant (Separation plant), System planning of water purification and soil treatment. Rental and production sales.
- This soil purification system cleans and classifies excavated soil on site into large gravel/sand and fine silt/clay.
- Since the system is operated on site:
- 1. Secondary pollution can be minimized.
- 2. Waste production can be minimized.
- This is an environmentally-friendly treatment system.
- This system can also be used to treat contaminated bottom mud produced during dredging operations.

Various contaminants, including heavy metals and mineral oils, can be treated. |
 |
|
 |
Because the treatment can be conducted onsite, transportation costs can be reduced and secondary pollution, such as CO2 emissions from transport vehicles,can be prevented. |
|
|
 |
Since cleaning water is recycled, the use of water can be minimized. |
|
|
 |
Contaminated soil is classified and treated, and the treated soil is backfilled. So, waste byproducts can be greatly reduced. |
|
|
 |
Clay containing contaminants is dehydrated and reduced in volume, so that final disposal volume is further reduced. |
 |
- Supplies regular amounts of soil stably.
- Washes clay away from the surface of sand and gravel, and makes clay lumps dissolve in water.
- Primary treatment
Classifies, treats and collects sand and gravel of 1-100 mm.
Secondary treatment
Lower: Classifies, treats and collects sand and gravel of 0.5-1 mm.
Upper: Classifies and collects fine sand of 0.075-0.5 mm.
- Wet cyclone
Classifies fine sand, silt and clay using centrifugal force.
- Coagulation-sedimentation equipment
Separates treated wastewater into supernatant water and sludge, and concentrates silt and clay.
- Compression filter press
Dehydrates sludge and makes the silt and clay cakey.
