Dewatering unit

Brightway Dewatering Unit includes a contained automatic flocculation unit with pumps, polymer preparation tank and mixing system. Dewatering system uses coagulant and flocculants chemicals including Poly Aluminum Chloride( PAC) and Poly Electrolyte(Polymer) to coagulate and flocculate the solids in the fluid and make the slurry in a condition that centrifuge can separate the solids from the mixture more convenient. Cuttings generated in the dewatering system are discharged by the centrifuge in the corral; liquid is discharge straight to one of the buffer tanks.

The Dewatering suction lines could be connected to middle mud pit and all ES tanks.

The gathered waste water in the waste pit or the amount of the mud which the mud engineer wants to dump ( usually at the end of drilling sections) should be transferred to the ES tanks or the mud pit and from there could be processed by dewatering system.
The overall objective of dewatering systems is to process drilling waste. Typical applications are:
 Reduction of the liquid waste volume generated
 Recycling back into the active fluids system
 Disposal
 Release in an environmentally safe and cost effective manner.

The main aim is to reduce well costs, either through a reduction in fluid volume used during the well, and /or through a reduction in disposal costs.
Dewatering systems have become major factors towards “closing the loop” in the dry location or zero discharge concept. The displaced or excess drilling mud along with the excess location liquids produced on the dry or zero discharge location are channeled to the collection pit and placed in the storage system. The dewatering system is utilized to process the liquid waste from the active mud and the storage system. The cleaned effluent from the dewatering system can then be :
1) Returned to the active mud system
2) Returned to the drill water tanks for use as dilution
3) Treated further to acceptable regulatory standards for release to the environment

Drilling Waste Management TDU

Indirect Thermal Desorption (TDU) applies heat to the contaminated soil while isolating the flame from the material.  The contaminant vapor is isolated, so it can be recovered, condensed, and recycled, eliminating long-term liability.

This TDU treatment is different to Brightway Drilling Waste Management System, which is mainly composed of vertical cuttting dryer and VFD decanter centrifuge by the physical principal of centrifugal force as below picture.

Brightway Drilling Waste Management

Here is the example of Brandt TDU. The cuttings are heated up indirectly in a large diameter, rotating dryer, with the contaminants being vaporized, as the cuttings move forward through the dryer to discharge.
The vapors are pulled from the dryer and filtered, to remove the dust particulate.
Vapors are then condensed to a liquid phase and are processed through an oil/water separation system.
Recovered water is used to rehydrate the cleaned cuttings while the recovered oil is used in new mud or fuel in the burners.
Stainless steel construction allows for the high temperatures necessary for processing drilled cuttings. Variable speed dryer rotation and positive sealing system to prevent discharge of dust and vapor.

A high temperature separator filters vapors, removing dust, leaving recovered oil clean.
Vapor Cooling System – Stainless shell & tube water-cooled heat exchanger, with closed loop cooling tower.
Oil/water Separation System – First pass through slant bed oil/water separator, then through a coalescer.
Soil Conditioner – dual shafted pug mill, with recycled water spray system to rehydrate and cool the cleaned cuttings.
Post Treatment Oil Uses
Use as base oil for drilling fluids
Send to pipeline for re-use
Use in burners to fuel the thermal process
Fuel for other industrial processes
Diesel engine fuel
Oil/water separators (heater treater)
Oil treaters
Asphalt plants
Steam generation
The Brandt THOR™ system uses the Best Available Control Technology (BACT) in the “state of the art” patented THOR process.
With the addition of the thermal oxidizer equipment on the new THOR system, stack emissions are below US EPA guidelines for this process and will beat our clients’ most stringent requirements.
The US EPA has designated this technology as the Best Demonstrated Available Technology (BDAT) for remediation of hydrocarbon contaminated soils.

This drilling waste treatment of TDU is complicated than our drilling waste management, while our sludge drying system can be completed further as the Zero discharge system by making the dried waste to be the solids bricks.

Guide air seat put in within the deaerator head, higher guide air seat cavity through the vacuum waterproofing plug and gas guide seat is axially organized pores with vacuum tank consistent.

When the liquid level within the vacuum degasser is accumulated to the liquid level float up, float through the link pin drives the guide tube to move; once the guide hole pipe through the air guide seat is organized on the radial direction of the opening and also the atmosphere at identical time, decline within the thermionic valve, the liquid drop, liquid level float to guide quiesce, guide tube and outdoors atmosphere between guide gas interface is reduced or closed, to take care of the vacuum degree within the vacuum degasser.

Due to the adoption of thermionic valve higher cavity and vacuum degasser to stay the pressure balance is consistent, will create the conducting pipe interface to extend, this will increase the sensitivity of the liquid level management device.

At identical time, vacuum degree to maximise the degasser in vacuum degasser permission, in up the the initial impact, additionally to the safe operation of the solids system is bonded.

How Vacuum Degasser Works?
There ar in the main four opening(mud water, footballer port, mud outlet and waste product drain outlet) within the process tan and every one of them ar connected by pipes. The gas cut in lubricating substance is delivered by the feeding pump into the vacuum degasser tank on tangent route through the water pipe. when the collision of a series baffles specially designed and put in within the inner wall of the tank, the exposure of the mud surface is enlarged and therefore the mud flows down in an exceedingly disturbed flow condition. Meanwhile,The mud and gas finished separation. Free gas is target-hunting through the footballer port connected by pipes at the highest of the tank to the safe place, then burned by the flare ignition device. lubricating substance when gas separation can flow into the treating tank for the additional treatment by the next equipements. like sedimentary rock shaker, mud cleaner and bottle centrifuge etc. The waste product within the degasser tank flows from the drain outlet at very cheap of the tank.

Mud Cleaner in Drilling Fluid Recycling System

The drilling mud cleaner is a major equipment in drilling fluid recycling system,we can design customized cost-effective mud cleaner for customers special needs. Brightway mud cleaner can meet almost all needs for oil & gas well drilling fluids treatment system and HDD mud recycling system.


When the mud cleaner handles the weighted drilling fluid, the drilling fluid which is already handled enters into drilling fluid system from the over fall of the swirler. The drill cuttings, barite and a little liquid phase discharged from the under set and go to the highly detail screen. Because of the granularity of barite is 2~74um mostly, it will return to the drilling fluid system with the liquid phase and the drill cuttings which are smaller than the sieve mesh, the drill cuttings which are larger than the sieve mesh will be discharged from screen surface. In this way, mud cleaner cleans the drilling fluid, stabilizes the performance of drilling fluid and recycles the barite and the liquid phase.


Mud cleaner is consist of manifold, shale shaker,desander and desilter. First the drilling fluids are sucked up to 0.25Mpa ~ 0.4Mpa by centrifugal pump, and enter into the cones through the side inlet which is normally only 2-1/2″ diameter. The fluids then flow spirally inside of the cone. Effected by the centrifugal force, the heavy solids in the fluids would be throwed towards the inner wall of the cones, go down to the bottem, and discharge through the sand discharge port, while the light fluids would go up and discharge through the upper oulet. The diameter of the bottom discharge port is adjustable, and with a cover of hydrocyclone.
