ZX Series Candle Filter for Chemical Solvent & Catalyst Recovery, 0.5-100μm Filtration

The ZX Series self-cleaning candle filter delivers a high-capacity, fully enclosed solution for industrial wastewater treatment and process water recycling. Optimized for medium-to-low solids content fine filtration applications, it removes suspended solids, precipitated heavy metals, and fine particulate from industrial effluents. An optional dry cake compression system enables significant sludge reduction (volume decrease), while treated effluent quality meets pre-treatment standards for process water reuse (RO feed, cooling tower makeup, plant service water).

• Optimized for Medium-Low Solids Fine Filtration: Designed for wastewater streams with up to 5% suspended solids, providing efficient fine clarification as a polishing step after primary sedimentation or coagulation-flocculation treatment.
• Enclosed Zero-Emission Design: Fully sealed filter vessel prevents odor and aerosol emissions, maintaining a clean and safe workplace environment compliant with industrial hygiene standards.
• Optional Dry Cake Compression System: Available mechanical compression attachment further dewaters the discharged filter cake, achieving up to 90% sludge weight reduction compared to conventional clarifier underflow, significantly lowering transportation and disposal costs.
• Process Water Reuse Quality: Treated effluent consistently achieves turbidity < 5 NTU and SDI < 5, meeting pre-treatment requirements for reverse osmosis feed, cooling tower makeup, and general plant service water, reducing fresh water consumption and wastewater discharge fees.
• One-Pass Complete Filtration: Achieves discharge-quality effluent in a single pass, eliminating multi-stage filtration and reducing equipment footprint by 70-80% compared to conventional clarifier systems.
• PLC 24/7 Automation: Automatic cycle management including filtration, cake drying, backflush discharge, and pre-coat renewal enables continuous unmanned operation with remote monitoring capability.

• Metal finishing and electroplating wastewater fine filtration
• Cooling tower blowdown suspended solids removal for reuse
• Reverse osmosis (RO) pre-treatment for SDI reduction
• Chemical precipitation sludge dewatering and volume reduction
• Quarry, mining, and glass grinding process water recycling
