4 Sets Drilling Mud Tank Cleaning Waste Water Treatment Unit for Africa

Recently 4 sets of drilling mud tank cleaning waste water treatment unit are ready for delivery to Africa.
The delivery of these four units marks a significant step in supporting sustainable drilling practices in Africa. In many African oil and gas operations, environmental regulations are becoming increasingly stringent. The improper disposal of tank cleaning wastewater which often contains heavy solids, oil, and chemicals will poses a significant environmental risk.

The four units of tank cleaning waste water treatment unit being shipped are engineered to provide a comprehensive zero- discharge solution. By effectively separating solids, oil, and water, the system allows for the recycling of the water back into the drilling process or its safe disposal, while recovering valuable drilling fluids.
The automatic tank cleaning unit can be made into complete skid system and 3 part system according to the footprint of the jobsite. The main components including strainer, suction pump, chemical doing unit, static mixer, inclined plate clarifier ( IPC), electrical membrane pump, buffer tank, centrifugal pump, and explosion proof control system.

Key Features of the Treatment Units:

High-Efficiency Separation: Utilizing advanced mechanical separation technology, the units effectively remove suspended solids and oil from the wastewater.

Compact & Modular Design: Designed for ease of transport and rapid installation, these units are ideal for remote drilling sites where space and logistics are critical.

Chemical Dosing System: An integrated automated dosing system ensures optimal treatment efficiency with minimal operator intervention.

Robust Construction: Built to withstand the harsh operating conditions typical of African oilfields, ensuring high reliability and a long service life

GN Solids control is a professional manufacturer of solids control and drilling waste management equipment. With a focus on innovation and sustainability, the company provides solutions to oilfields worldwide, helping the operators to reduce their environmental footprint and improve drilling efficiency.

Tank cleaning unit and oil waste separation system

As the manufacturer of tank cleaning unit and oil waste separation system in China, GN solids control has designed and produced customized tank cleaning unit and oil waste treatment system for our client.


GN automatic tank cleaning unit is a closed loop system to clean the mud tank , oil tank, chemical tank and slurry tanks. GN tank cleaning unit can supply fresh water to the high pressure tank cleaning machine/nozzle which is mounted inside the tank to be cleaned. By the tank cleaning continuous process, it will minimize the water consumption and manpower. The high pressure pump is installed on the one skid tank cleaning unit which is used to supply the fresh water to the high pressure cleaning nozzle. We have two different design for the tank cleaning unit, one is the one skid design, all the components are installed on one skid for convenient transportation; the other one is the 3 skid design, it is composed of suction and discharged skid, treatment skid, storage skid, each skid with DNV lifting frame for operation at offshore rig platform. We can provide CNEX, ATEX and IEC EX as per project requirement.


After treated by the tank cleaning unit, the fluids can be treated by three phase decanter centrifuge separation system for oil, water, solids separation, the treated water can be also supplied to the high pressure cleaning machine, the oil can be recovery and the solids for final disposal. The three phase decanter centrifuge GNLW364 is designed for solids liquid liquid separation, with capacity 5m3/h. The max speed is 3964rpm and max G force 3200G. The screw propeller is protected by tungsten carbide tiles for longer working life. The mud distribution nozzle is protected by tungsten carbide inserts.
