A Fully Integrated, Multi-Module System

The GN containerized system combines several purpose-built modules—including a pre-mixing tank, vibrating screen, three-phase decanter centrifuge, and chemical dosing unit—into one compact, mobile platform. Each module is precisely engineered to manage a specific stage of the treatment process, ensuring seamless and high-performance operation from start to finish.

The system employs a chemical-assisted mechanical separation process to fully treat oily sludge. Sludge is first heated and conditioned in the pre-mixing tank, then coarse solids are removed through the vibrating screen. The conditioned material is subsequently fed into the three-phase decanter centrifuge, where dewatering and precise oil-water-solid separation take place. Strategic chemical dosing further boosts oil recovery rates, ensuring that all treated output meets stringent discharge and environmental compliance standards.
