Aluminum Ion Stabilizer for Anodizing Lines | ME-AL Acid Recycling Equipment

ME-AL Aluminum Ion Stabilizer is core environmental & process equipment matched with automatic, vertical, manual anodizing lines, independently developed by Guangdong ME-AL Technology Co., Ltd.

During continuous aluminum anodizing production, aluminum ions keep accumulating inside sulfuric acid tanks, raising bath conductivity resistance, causing uneven oxide film, color difference, increased power consumption and frequent bath replacement. 

The system adopts acid-resistant delivery pumps to transfer anodizing liquid into separation modules. Specialized membrane media rapidly separate aluminum ions from sulfuric acid: concentrated aluminum ion waste liquid is discharged out of the tank circulation loop, while purified sulfuric acid flows back to the oxidation tank for repeated use. It locks aluminum ion concentration within ideal process range all day long, delivering stable anodizing quality, chemical recycling and environmental emission reduction.

1. Circulation pump extracts contaminated anodizing solution from oxidation tank
2. Multi-stage pre-filter removes suspended impurities to protect separation membrane
3. High-efficiency separation membrane intercepts dissolved aluminum ions; free sulfuric acid permeates through the membrane
4. Regenerated clean acid flows back to production tank for cyclic utilization
5. Concentrated aluminum-rich waste liquid is collected separately for centralized treatment
6. PLC full-automatic circulation, real-time monitoring of permeate conductivity, no manual intervention

1. Stable Aluminum Oxide Film & Coloring Quality
   • Maintains aluminum ion concentration in optimal process range consistently
   • Eliminates oxide film thickness deviation, white spots, streaks and post-sealing discoloration
   • Provides stable bath condition for subsequent electrolytic coloring, ensures uniform bronze, black, champagne color tone
2. Significant Production Cost Reduction
   • Recycle more than 98% sulfuric acid, drastically cut new acid procurement frequency
   • Reduce bath renewal frequency, lower chemical raw material consumption
   • Lower tank liquid resistance, decrease overall power consumption of rectifier power supply
3. Environmental & Wastewater Treatment Benefits
   • Concentrate aluminum waste liquid separately, reduce total wastewater volume by over 70%
   • Lighten load of factory wastewater treatment station, save chemical dosing cost for neutralization
   • Meet strict local industrial waste emission standards, avoid environmental penalty risks
4. Low Labor & Maintenance Cost
