Desanders used for wastewater treatment process

Desanders are used to remove suspended solids from liquid process streams. One of the primary applications is to improve the quality of waste water. Treatment of waste water normally involves multiple process steps to remove the impurities and ensure that the final effluent discharge is compliant to regulatory specifications.


A desander has an entry port near the top on the side of the vessel, a hydrocyclone central component, and two discharge points (one on the top of the vessel and one on the bottom). The hydrocyclone is oriented so that the wide opening is at the top and the narrow opening at the bottom.

In terms of waste water treatment, the specific role of the desander is to remove solids which may contain some bacteria, thereby improving the clarity of the water.
Wastewater and other product streams in any industry where suspended solids may be present can benefit from the introduction of a desander in the treatment process.

Contact DC Solid control for more information about desanders and water treatment. DC Solid control offer highly technical expertise, excellent quality equipment and a personalised approach to your business’ needs. We can easily combine our solutions to suit your specific business, compliance and investment requirements.

Mud gas separator of drilling fluid circulation system

Mud gas separator (also called poor boy degasser or gas-buster) is a vertical vessel which is used to remove undesired gas from drilling mud when it returns from the well while circulating mud in order to control the well. Mud gas separators are commonly used during oil drilling operations, particularly in situations when
extraction is likely to yield a large volume of gas.


Often referred to as degassers, these systems offer many benefits when drilling operations are centered on mud columns that are below optimal balance, and in so-called “sour gas” environments when there is a high concentration of hydrogen sulfide in the drilling fluid. Tech-Fab fabricates and manufactures custom mud gas separators for the oil and gas industry and more.



Features of mud gas separators :
High efficiency and easy to maintain
Large capacity
Easy transportation and installation.
Maximizes free gas/mud separation
Unique U-shaped tube design eliminates moving parts and ensures a positive fluid seal, maintaining safe mud levels
Efficient baffle arrangement to easily separate gas from fluid
Available in varying sizes and lengths, accommodating any volume of fluid with high concentrations of gas
Heavy-duty steel construction and adjustable mounting skid for any rig

DC Solid control offers cost-effective Mud cleaners

Mud Cleaner is the second phase or the third phase solids control equipment, and it is a combination of desander, desilter and underneath shale shaker with the features of compact structure, small footprint and great efficiency. It is an ideal equipment as the second or the third phase solids control equipment.

Mud Cleaners can be used as economical and efficient single units on their own or alternatively used with desilters placed downstream for further fine cleaning of the mud.

mud cleaners

The mud cleaners from DC Machinery provide compact, energy efficient cleaning for flows of between 60 and 300m3/hr include primary screening, hydrocyclone feed pump, hydrocyclones and dewatering screen.

mud cleaner

Mud cleaner mud flow is decided by desander & desilter size and qty. The desander cone normally choose 10 inch size and desilter cone choose 4 inch size. Once cone size is fixed, the mud flow will be fixed depending on cone qty.

If you have any questions of mud cleaners, please contact DC Machinery.

1500HP Drilling Rig Solids Control System Package for Malaysia Project

Last Month, DC 1500HP drilling rig solids control system is under final assembling and test running procedure, and then will be ready for delivery. DC Solid control is able to provide the solids control system per customers’ specified requirements and also give constructive suggestion.



Normally, a complete drilling rig solids control system is consisting of several tanks, each tank would be installed with different equipment, some are for mud recycling, while the others for mud mixing. In this order, the client required our engineer to go their drill rig site to install and commissiong the solid control



The mud recycling tank in this order includes shale shaker, vacuum degasser and mud cleaner unit. 3 units DCS700-3 shaker are capable for the flow rate up to 300 cubic meters per hours per mud condition. By control the valve on mud distribution box, mud engineer on site could decide how many shakers to be used based on the mud flow
from rig.

Besides the petroleum industry, DC solids control system is also well known and widely used in trenchless industry. If you have requirements of any flow capacity solid control system. Please contact DC Solid control

Drilling fluid shale shaker and mud cleaner delivery to TianJin Railway station

Shale shaker and mud cleaner are the very important equipment for solid control system. Last week. DC Solid control finished the order of 3 sets mud linear motion shale shaker and 6 sets mud cleaners for a Kazakhstan clients used for oil& gas drilling field.

mud cleaners

The model of the shale shaker in this order is DCS700-3

The DCS700-3 shale shaker is a high cost effective model for drilling fluid processed shale shaker. The shaker with long OLY vibration motor and hookstrip shaker screen. The shaker is available in both 3- and 4-panel designs. With the advantages of fast, easy, and reliable screen panel tensioning is provided by two pairs of Rapid-Change draw bolts on each side of each screen panel.

The stock of vertical mud agitator discount sales

Mud agitator is an important equipment of mud tank surface product whose function is prevent mud in the tank sediment. Because it locate on the surface tank, so there are many different models of mud agitators because of the different tanks depth and width.

Now, in DC Solid control warehouse, there are 60 sets vertical mud agitators, they are JBQ5.5, JBQ7.5, JBQ15 and ect. All with different shaft lenght accroding to users requirements.

mud agitator

The DCSJBQ Series Vertical Mechanical Agitator is ideal for installations with limited footprint availability. These double-reduction, in-line, helical gear agitators provide smooth, vibration-free operation and efficient mixing, just like the right-angle drive agitators.

Vertically mounted agitators are lighter than right-angle-drive horizontal units, but produce the same mixing results. In some instances, horsepower requirements are reduced due to the 95% efficiency of the helical gearing. Above 7.5 kW mud agitator using turbine worm reduction drive, has the transmission torque, smooth operation, reliable work, etc advantages.

DC solids control equipment for HDD

The main function for a drilling fluid in HDD applications is hole cleaning. It is crucial to avoid cuttings beds forming, a build-up of drilled cuttings on the low side of the hole. Equally as important is promoting hole stability.

solid control equipment

A typical HDD solids control system will employ a combination of shaker, hydrocyclone, mixing, pump and compartmentalized tank technologies. The shaker is vital to the solids control system and is considered the first line of defense. Located directly downstream from the shaker will likely be a hydrocyclone assembly that will employ
desilters, desanders or both.

solid control system

We can achieve stability by keeping the hole full of drilling fluid, but also by maintaining formation integrity with adequate filtration control, encapsulation and inhibition of certain formations.

DC Machinery specialised solids control equipment for HDD. DC machinery also offers a range of centrifuges which remove solids in the drilling fluid down to 5 micron, allowing even greater control of the mud system, minimising dumping and saving costs.
