ZX Series Candle Filter for Chemical Solvent & Catalyst Recovery, 0.5-100μm Filtration
ZX Series Candle Filter for Industrial Wastewater & Process Water Treatment
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).
Frequently Asked Questions
What types of industrial wastewater can the ZX Series treat effectively?
The ZX Series is optimized for medium-to-low solids content fine filtration across a range of industrial effluents: metal finishing wastewater (metal hydroxide precipitates), chemical plant process water, cooling tower blowdown, glass and ceramic grinding water, and quarry wash water. For highly corrosive streams, SS 316L or specialty alloy construction is available.
How does the optional dry cake compression system reduce sludge disposal costs?
The compression attachment applies mechanical pressure to the discharged filter cake post-backflush, further reducing moisture content. Combined with the inherent dry cake discharge (25-40% moisture vs. 95-98% for clarifier sludge), the system can achieve up to 90% sludge weight reduction, resulting in proportional savings on transportation and landfill or incineration disposal costs.
Can the treated effluent quality meet process water reuse standards?
Yes. With appropriate upstream pre-treatment (pH adjustment, coagulation/flocculation), the ZX Series produces effluent with turbidity < 5 NTU and SDI < 5, consistently meeting pre-treatment requirements for reverse osmosis feed water, cooling tower makeup, and general plant service water, enabling meaningful fresh water reduction and wastewater discharge minimization.
How does the ZX Series compare to conventional clarifiers or filter presses for this application?
Compared to clarifiers, the ZX Series requires 70-80% less footprint, produces directly dewatered cake with the optional compression system, and achieves superior effluent clarity suitable for RO pre-treatment. Compared to filter presses, it operates in continuous/intermittent mode (not batch), requires no filter cloth replacement, and reduces labor through full PLC automation.
