With the development of the petroleum industry, oil sludge treatment has become an increasingly prominent environmental issue. Traditional treatment methods are inefficient and cause serious secondary pollution. The introduction of horizontal screw centrifuge technology provides an efficient and environmentally friendly new solution for oil sludge treatment.
Traditional horizontal screw centrifuges are mainly used for solid-liquid separation, whereas oil sludge treatment requires the separation of three phases: solid, liquid (water), and liquid (oil). Jiangsu Longdai Environmental Protection Group Co., Ltd., with strong independent research and development capabilities, has overcome this technical challenge. Our designed horizontal screw three-phase centrifuge effectively separates the oil phase, water phase, and solid phase (sludge) in oil sludge through its unique drum and screw structure, along with precise differential speed control. The separated oil phase can be recycled, the water phase can undergo further treatment for standard discharge, and the solid phase can be processed harmlessly as sludge, achieving resource recycling and significantly reducing environmental pollution.
As a company with on-site factories and production lines, we provide three-phase horizontal screw centrifuge solutions to several petrochemical companies. Our products have been exported to oil-rich countries such as Russia and Turkey, receiving high recognition. These cases fully demonstrate that we are not only experts in solid-liquid separation but also innovators in the field of three-phase separation. We continually invest in R&D, committed to providing more advanced and environmentally friendly solutions for global customers, which is our core competitiveness as a professional horizontal screw centrifuge manufacturer.
