A complete wastewater treatment system manufactured by GN Solids Control has been shipped to an African oilfield to support drilling and produced-water treatment. The package integrates four major functional modules: the Pre-Mixing module, the decanter centrifuge module, the chemical dosing system, and the clean-water recovery and transfer module. This modular design ensures reliable solids-liquid separation and stable operation in demanding oilfield environments.

The process begins with the Pre-Mixing module, which homogenizes incoming wastewater containing mud, fine solids, and oil residue. Proper Pre-Mixing greatly improves downstream separation efficiency and helps maintain consistent feeding conditions for the decanter centrifuge.

The second stage features the high-speed decanter centrifuge, which generates strong G-force to remove fine and ultra-fine solids. GN’s centrifuge technology ensures continuous operation, low maintenance, and high clarity of discharged liquid.

To enhance separation performance, the chemical dosing module prepares and injects flocculants automatically. Accurate dosing helps the centrifuge capture ultra-fine particles and produce cleaner water suitable for reuse.

Finally, the clean-water recovery module collects and transfers clarified water to storage or reuse points. This reduces freshwater consumption and improves the environmental footprint of the oilfield operation.

With integrated Pre-Mixing, decanter centrifuge, chemical dosing, and water-recycling technologies, GN Solids Control continues delivering reliable solutions for global wastewater treatment challenges.
