KUGLER® technology for dewatering drilling mud and bentonite slurry
The KUGLER® BTC drilling mud complete solution was developed to separate drilling mud back into sturdy material and clear filtrate.
Drilling wastewater with a finely distributed solids load is very difficult to transport and dispose of, due to its high water content.
This is where Kugler’s process comes in. It was developed in order to obtain a solid medium for the disposal of the drilling mud, which can be easily transported away. In addition, a solids-free, clear filtrate is obtained that can be returned to the process.
Disposal of drilling mud / Disposal of bentonite mud
Dewatering solution for the treatment of:
✓ Drilling mud suspension
✓ Bentonite mud
✓ Sand and gravel washing sludge
Detailed process description
How it works: With the help of this KUGLER® process you avoid the costly transport and disposal of the drilling mud with suction trucks. A tailor-made solution for any drilling and bentonite suspensions – by means of flocculation/conditioning and a static dewatering you remove the water from the drilling mud until a sturdy and easily transportable material remains in the container. The following diagram illustrates the few, uncomplicated process steps of our complete solution for dewatering drilling and bentonite suspensions.
Watch our video on the complete solution from Kugler. You can find it in the “Video” tab above.
Development of the mud over time
Filling of the dewatering container with flocculated drilling mud; total filling volume with simultaneous dewatering (filtrate discharge/return) → in general within 1 to 3 h (depending on TS content) – post-dewatering of the batch (if necessary overnight) with vibrator motor (timer) – conditioned drilling mud dewaters – sturdy material (after max. 16 h), empty container and start next batch.
The following are example pictures:
Components of the complete drilling mud solution
A core component of the complete drilling mud solution is the KUGLER® BTC, a dewatering container (EWC) especially for drilling muds (see functional diagram on the right). This dewaters statically via gravity and sedimentation, which is why the drilling technology container is almost maintenance and wear-free.
The Kugler® EWC consists of an outer standard container and a removable inner basket with a robust filter fabric. The water flows off over the filter surface, then the sturdy sludge is transported in the container and simply tipped out. The dewatering process is optimised by a timer-controlled high-frequency vibration motor and an additional middle filter partition to increase the total filter area.
FlocTower®
The KUGLER®-FlocTower is a complete system for dosing a broadband polymer (flocculation aid) via the precisely coordinated, necessary energy input. Via mixing and floc-formation module for flocculation and dewatering of the sludge. FlocTower completely manufactured from V2A stainless steel incl. the entire periphery consisting of:
→ floc forming ∙ filtrate recirculation
→ Submersible pumps & peripherals (incl. hose connections and power connections)
