Dredge Slurry Separation System

River dredging process system is generally adopts a cutter suction dredger to absorb the muddy water mixture at the bottom of river, and then transport it along the pipeline to a sludge drying treatment field. After machine sorts the garbage mixed in mud, the mud is passed into the concentration tank in the field, and the mud water separation is carried out through the mud treatment system. Finally, water reaches the standard discharge, and the wet sludge is sent to sludge dewatering equipment to dehydrate and becomes solidified mud cake for reusing.

Dredge Slurry Separation System mainly used for the separation of sludge from rivers. KOSUN Dredge Slurry Separation System is consist of shale shaker, desander, desilter or decanter centrifuge for 3 to 6 stage separation depending on the needs.

KOSUN Dredge Slurry Separation System is consisting of 3 parts. The first one is the dredging boat and first stage separation pool for large size of the trash. The dredging boat is always moving on the surface of the lake or river, and the suction unit would go down deep to the bottom of the lake or river and then suck sludge then transfer to the ground by a hose which is always float on the water surface. On the ground, there will be a pool which is divided into several parts by different mesh size of wire screen. The sludge flow coming out from the hose will get into the pool; the large size of the trash in the sludge would be blocked by these several wire screens, while the slurry will flow away for next process.

The second part of the Dredge Slurry Separation System is the recycling system which is including several equipment that is used especially for the solids and liquid separation. The slurry will be fed into a scalping shaker, here the solids which is large than 1/8 inch would be separated out, and the slurry would then be pump transferred to the desander for much fine solids removing. After treated by the desander, almost all the solids with size of 50 microns would be removed out.

The third part of the Dredge Slurry Separation System is the ultra-fine solids removing equipment. Some contractors like to use the filter press as the final solids removing units, the solids separated are really dry and shaped like cake. While another option is to use the decanter centrifuge that could be used to remove the ultra-fine solids with size down to 2 microns. After treated by the filter press or the centrifuge, the water is already clean that could be flow back to the lake or river.

Tunnel muck treatment System-KOSUN

Xi’an KOSUN Environmental Engineering Co., Ltd. focuses on development and services of complete technologies and equipment of sludge and Tunnel muck reduction and resource utilization.Our Tunnel muck treatment System had been successful used in shenzhen,China.

Tunnel muck should be considered as a valuable resource: if it is managed and treated correctly, it can be used for different purposes. This would lead not only to environmental benefits but also those of an economic nature. This work is part of the REMUCK project and it has the purpose of evaluating the effects of different treatments on different types of excavated rock. Five case studies have been selected and, of these, two were excavated with TBM (the Torrent-La Thuile tunnel and the Brennero tunnel), one with EPB (the Turin underground railway) and two using traditional excavation methods (Turin underground railway station and the Omegna tunnel). Tests have been carried out in the laboratory on both the muck in its natural state and on muck treated in two different plants (a mobile plant and a fixed plant) in order to characterise the aggregates from the shape and mechanical resistance points of view (according to EN 933-3 and EN 1097-2, respectively). The results of these tests have been compared with the threshold values foreseen in a muck management plan for a tunnel in Switzerland in order to verify the quality of the treatments the recycled aggregates were subjected to. This has made it possible to evaluate the suitability of the treatments, on the basis of the foreseen types of use, and to propose alternative working schemes for the nonconforming cases.

Italy is one of the first countries in the world as far as the number of tunnels is concerned. Many new tunnels are currently under construction or have been planned (300 km of railway tunnels and 150 km of road tunnels, some more than 500 m long, but also metropolitan tunnels). Tunnels are usually excavated in mountain areas of great value: the longest ones in Italy are in fact located in the Alps or in the Apennine mountain range. Approach: If the re-use of excavated material is not taken into account each time a tunnel is excavated, new quarries are required to obtain aggregates for cement, asphalt and concrete and new landfills are created, to allocate the tunnel muck. If the planned tunnel is large (in size and length), numerous quarries and landfills can be expected in the vicinity of the tunnel, with a consequent considerable amount of environmental damage. Results and Conclusion: For these reasons and not only for the obvious economic reasons, it is necessary to develop all the technologies that make the re-use of muck possible as an aggregate for cement and asphalt and as material for road and railways embankments.

Piling Mud Treatment Solution-Pilling Slurry Separation Plant

Pilling Slurry Separation has always been a problem in engineering construction. In the process of piling, there will produce a lot of mud, the mud is suspension liquid contains a certain amount of fine clay particles, which has a certain viscosity and difficult to separation for a long time.

Now how can we treatment these mud from piling? There are four Pilling Slurry Separation Methods:

Pilling Slurry Separation Plant

1.Pilling Slurry Separation Plant: This method is to use the special pile mud treatment equipment to separate the mud from slurry water. Such as piling mud centrifuge, piling mud dewatering machine, piling mud separator, piling mud curing equipment. The biggest advantages of this method is convenient and effort. Sludge treatment efficiency, more environmental protection.

  • Pilling Slurry Separation Method of Sedimentation basin : On construction site, we can construct one sedimentation basin. First, we need to discharge sewage into sedimentation basin. Removing suspended solids, oil material and Neutralization processing, after detection to achieve discharge standard, we can discharge into the river.


3.Pilling Slurry Separation Method of Natural dehydration: In the process of drilling perfusion, we can use shaker screen to seprate small gravel, sand and other solid particles from pile mud. then discharge it into mud pit and sufficient to precipitate until the natural dehydration and solidification.


4.Pilling Slurry Separation Method of Flocculation Treatment: For waste mud water, we can add flocculants into it. Because the mud is suspension liquid contains a certain amount of fine clay particles, the macromolecule flocculant is a kind of water-soluble polymer,When mixed with mud water, it can destroy the stability of the slurry water in order to settlement of clay particles from the water condensed quickly.

There are three types of mud shale shaker motion.

In the process of oil drilling drilling fluid from internal carotid out through shale shaker, then in other solids control equipment, in the solid phase removal equipment of shale shaker is itself a filterability spate separation equipment, in the mud of a complete set of cleaning system, it has the first, the characteristics of fast drilling fluid solid phase separation, at the same time is also a kind of economic, efficient spate separation equipment.

There are three types of mud shaker motion: circular, elliptical and linear motion, the oscillator in the center of gravity, will produce circular motion; When the oscillator is above the center of gravity of the system, elliptic motion is generated. However, for elliptic motion, the screen surface must have a slope in order to utilize the conveying cuttings, but the screen capacity will be reduced. The linear motion is to put the oscillator in front of the center of gravity of the system, making the screen frame produce linear motion, thus clearing the solid phase. The vibrating screen moves in a straight line with its fixed cuttings transfer speed. The screen surface can be flat or slightly tilted.

The ES series elliptic vibrating screen of KOSUN adopts the long tube vibrating motor as the power source, the performance is superior, the structure is reasonable, the operation is stable, the life is long, the maintenance cost is low. Under the same conditions, compared with other types of shaker, drilling mud processing capacity and sand transport and discharge capacity can be greatly improved, and can effectively overcome the “screening”, “screening paste” phenomenon.

KOSUN LS series linear vibrating screen using the vibration motor excitation to cheer for the vibration source, make the material being thrown up on screen, at the same time, forward a straight line with low consumption, high output, simple structure, easy maintenance, fully closed structure, no dust overflow, and the advantages of automatic discharge, more suitable for assembly line, at the same time family newsletter QZS linear vibrating screen can also be adjusted through the AWD regulating series of solid separation effect.Linear vibrating screen has obvious advantages in the treatment of large displacement drilling fluid. In this condition, the strong excitation force output by the linear vibrating screen can quickly remove a large number of solid phases through efficient linear vibration trajectory, which can effectively remove large particles in the drilling fluid.

Drilling fluid linear vibrating screen in the processing of drilling fluid.

The linear vibrating screen USES the short or long tube vibration motor as the power source, the performance is superior, the structure is reasonable, the operation is stable, the life is long, the maintenance cost is low. Under the same conditions, compared with other types of shaker, drilling mud processing capacity is stronger, sand transport chip capacity is greater.

Purpose of linear vibrating screen: LS series vibrating screen is the first stage solid control equipment for the processing of drilling mud, which is more suitable for the occasions requiring large handling capacity. Solid particles with particle size greater than 76 microns in drilling mud can be separated. Application: large oil rig, large trenchless rig, shield engineering, river dredging engineering, etc.

Drilling fluid linear vibrating screen in the processing of drilling fluid if the phenomenon of running mud?It is understood that this is mainly related to the high solid content in the drilling fluid, mud viscosity, cuttings dispersion and other screening material factors;It is related to the condition of small vibration force, high mesh number and small screen area of drilling fluid vibrating screen.It also has a lot to do with the direction and position of the input buckle of the vibrating screen during the field installation, which can be analyzed step by step from the following points:

1. Regularly check the steering of the motor;

2. Unreasonable mesh number;

3. The formation and mud conditions affect the treatment capacity;

4. Check the amplitude of the shaker;

5. Check whether the distribution of liquid flow on the screen frame is reasonable.
