ZX Series Candle Filter for Biodiesel & Fuel Oil Purification, 10-80m³/h

The ZX Series self-cleaning candle filter provides a robust, fully enclosed purification solution for biodiesel processing and fuel oil treatment. Engineered for high-temperature operation up to 150°C, it removes glycerol, soaps, catalyst residues, and particulate contaminants from biodiesel and heavy fuel oil. The system supports 24-hour continuous operation with automated intermittent backflush cycles, enabling uninterrupted production in refinery and blending facilities.

• High-Temperature 150°C Rated Design: Fully sealed system engineered for continuous operation up to 150°C, processing hot biodiesel and heated heavy fuel oil without performance degradation or seal failure.
• Glycerol, Soap & Impurity Removal: Effective removal of free glycerol, soap residues, catalyst particles, and other process impurities after biodiesel transesterification and water washing stages, helping meet ASTM D6751 and EN 14214 specifications.
• 24-Hour Continuous Intermittent Operation: PLC automation enables round-the-clock production with automated cycle management. The filter runs extended filtration phases with brief, scheduled backflush intervals, maximizing throughput while maintaining consistent product quality.
• Viscous Fluid Handling: Compound multi-layer filter candles with optimized flow channels handle fluids up to 500 cSt viscosity without excessive pressure drop, suitable for both thin biodiesel and heavy residual fuel oils.
• Filter Cake Drying Fuel Recovery: Nitrogen-purged cake drying recovers entrained fuel from the filter cake, maximizing product yield and reducing hazardous waste disposal volumes.
• Nitrogen Backflush Safety: Inert gas backflush ensures safe dry cake discharge, critical for processing fuels with low flash points in continuous operation mode.

• Biodiesel final polishing (FAME) after transesterification and washing
• Heavy fuel oil (HFO) purification before marine engine and power plant use
• Waste cooking oil pre-treatment for biodiesel feedstock preparation
• Pyrolysis oil particulate removal and contaminant reduction
• Lubricating oil re-refining and industrial oil regeneration
