Ⅰ.INTRODUCTION OF KOSUN Slurry Separation Plants, Mud separation units
Environmental slurry separation plants developed by KOSUN is the most advanced technological products in the world, which can be widely used in urban rail transit construction, water conservancy and hydropower construction and municipal engineering. In the next 20 years, the construction of domestic infrastructure will be the key fieleds invested by the State. KOSUN slurry separation plants can meet the environ mental requirements on urban construction and processing. The market demand of environ mental slurry separation plants will be increasing.
KD series slurry separation plants is a kind of professional mud treatment equipment developed by KOSUN, which is suitable for purifying slurry in the mud-water balance shield, diaphragm wall, pile foundation and other projects in the process of circulation drilling. It is used to control the mud performance, enhance the quality and efficiency of hole making, support and ensure the safe and smooth operation of roadheading equipment, and improve the recycling of the mud. KOSUN slurry separation plants can save construction costs, reduce mud emissions and reduce environmental pollution. It is an economical, efficient and environment-friendly necessary construction equipment.
Ⅱ.APPLICATION OF KD Slurry Separation Plants, Mud separation units
（1）Slurry balanced shield mud treatment;
（2）Bored pile foundation construction mud treatment (generated by rotary drilling rig, positive and reverse circulation drill and percussion drill during drilling and pore forming);
（3）Underground diaphragm wall construction mud treatment (generated by diaphragm wall and double wheels trench cutter during trenching);
（4）Trenchless construction mud treatment (generated by horizontal directional drilling and slurry pipe jacking).
Ⅲ.STRUCTURE AND FUNCTION OF KD Slurry Separation Plants, Mud separation units
KD series slurry separation plants mainly consists of scalping shaker module, desanding module and desilting module. As a pre-screener, the scalping shaker can remove coarse particles from mud. The desanding module is equipped with desander (primary cyclones) and fine-mesh shaker and mainly removes granulated sand. The desilting module is equipped with desilter (secondary cyclones) and can conduct a fine separation selectively according to the field needs of customers. Mud closed-loop circulating purification mode and lower water content in slags help reduce the environmental pollution. Wear parts of the system are of anti-corrosion and wear-resistance, long service life and low failure rate, and the system can be suitable for various severe working conditions.
Ⅳ.OVERALL ADVANTAGES OF KD SERIES Slurry Separation Plants, Mud separation units
(1) Simple and useful treatment process, as well as convenient installation, operation and maintenance;
(2) Modular and integrated design, transportation and installation subject to standard container size, foldable operating platform, compact structure, small footprint and flexible field use;
(3) Adjustable G-force of shale shaker, screen panel angle and mesh size, strong overall system adaptability and easier treatment of materials from various formations;
(4) Meet separation requirements on various materials and customize process as per the cut point of D 50 ; meet the requirements on different handling capacities, 100~3000m³/h;
(5) Meet various power specifications as per construction needs, and even generator set can be used for operation;
(6) The whole system is skid-mounted integrated system and can be also changed into vehicle-mounted mobile treatment units.

Slurry wall separation unit (or diaphragm wall separation unit) are being used in underground wall construction (off course, the Slurry wall separation unit (or diaphragm wall separation unit) being placed above the ground), and the main function is to recycling the slurry (mud) and removing the solids from the slurry as well using in work.
diaphragm wall separation unit
Many product in slurry wall separation unit can burns on skin due to their low temperatures. Exposed body part can be torn as it has ability to stick to cold stuffs due to availability of moisture. These liquids can also cause
– Hypothermia or Frostbite
– Serious respiratory problems like pneumonia if cold gas is inhaled
– Reduced vision
Hazards from oxygen in diaphragm wall separation unit of Slurry Separation plants.
Oxygen is not a combustible gas but it helps flames to keep on going. Also hydrocarbon materials of lubrication oils react vigorously with oxygen and it should be avoided in all cases. Oxygen concentration should be kept below 23.5%.
Slurry Separation plants
Gas products occur need slurry separation plants.
Oxygen is most required for life support. When enough quantity of argon and nitrogen is present in environment it can lead to depletion of oxygen. Increase in hydrocarbon can also lead to symptoms like nausea or dizziness. In such cases one should come or brought out immediately. With time body returns to normal state once out of these conditions.
Protected clothing helps in protection of body from fire hazards or oxygen or cryogenic liquids.
– Leathers gloves should be used as their fitting is loose and can be easily removed in case of burns.
– Face shield to cover the face should be used.
– Footwear should be devoid of metals or nails as they can cause sparkling.
– In cases of trapped vapors, clothing should be opened and closed immediately
In slurry separation plants, like Kosun from China, the different parameters been collected in real spots and researched in labs, and finally give the corresponding solutions for remove the solids in constructions, like slurry wall separation or diaphragm wall separation.
Slurry Separation Units in Slurry Treatment were mainly refer to mechanical system used during oilfield drilling work, just like TBM separation units – the slurry separation units(or Slurry Separation stations, Slurry Separation plants)are often been called mud separation units(or Mud Separation stations/mud Separation plants). The main component of the system are consisting by shale shaker(or vertical dryer), centrifuge and mud cleaner in general. And these units are just helping the engineers in real projection solving the problem about mud clean and recycle of the slurry.
Here you can find sample picture of Slurry Separation Units like the following:
Although the main application area is in oilfield drilling, in the following industry or circumstances, the slurry separation units also take tribute in the work: Infrastructure construction, environmental protection industry.
For example, in trenchless HDD projection, trenching mechanics need special mud in working for many functions like lubrication and keep tunnel wall “strong” enough for preventing collapse. Or in pile foundation engineering work, these mud or slurry are very important in different functions, and all these mud need reuse or make it can be recycling again, then the slurry separation units by Kosun give the good solution. All the units are manufactured by Kosun’s own factory and serving clients well by 24 years experience.
To separate the solid material from the slurry water, the slurry separation unit be deployed to the projection site. The unit uses a series of sieve screens and hyrdocyclones and will remove solids from the slurry water down to about 60 microns particle size, and this parameters are different from project to project and only the customized slurry treatment system by specialists can meet the real needs in construction site.
