Advanced Technology for Onsite Sludge Reduction and Oil Recovery
GN Solids Control has successfully shipped two GNOST-15 oil sludge treatment systems to an industrial customer in Asia. Designed for efficient oil recovery and environmental protection, each system is tailored to handle complex oily waste streams generated from tank cleaning, refinery waste, and drilling mud pits.
Full-Process Modular Solution
Each GNOST-15 system consists of seven functionally integrated modules:
-
Sludge Transfer Pump – Transfers raw sludge into the treatment line
-
Pre-Mixing Tank – Heats and blends sludge to optimize fluidity and separation
-
Vibrating Screen Module – Removes larger solid particles
-
GNLW-554 Decanter Centrifuge – Separates fine solids from the fluid phase
-
GNLWS-554 Three-Phase Centrifuge – Recovers oil, separates water, and minimizes residuals
-
Chemical Dosing System – Adds treatment chemicals for improved efficiency
-
Steam Generator – Provides heat to assist in emulsified oil breakdown
This modular system allows for continuous, automated sludge treatment with compact layout and flexible deployment. The combination of two-phase and three-phase separation technologies ensures maximum recovery of valuable oil while significantly reducing hazardous waste volumes.
The client selected GN’s system due to its proven performance, easy maintenance, and field adaptability. These units will be used in a long-term sludge remediation project in Southeast Asia.
GN continues to serve global clients in energy and environmental industries with customized, cost-effective treatment solutions that meet local regulations and ESG goals.
