MEI-Al Wastewater Treatment System for Aluminum Anodizing Line, Both Environmentally Friendly and High-efficiency

Guangdong ME-AL Technology Co., Ltd, a professional full-chain supplier of aluminum alloy surface treatment equipment, develops customized dedicated wastewater treatment systems supporting all types of anodizing production lines. Our equipment professionally treats acidic wastewater, alkaline wastewater, aluminum-containing wastewater, and high-COD coloring wastewater generated from degreasing, caustic etching, neutralization, anodizing, dyeing and electrophoresis processes. Fully designed to meet local environmental emission standards, the system can be integrated with your existing oxidation line without extra factory reconstruction. It effectively solves critical environmental risks including excessive discharge, environmental inspections and production shutdown caused by unqualified wastewater. It is an essential environmental supporting facility for aluminum extrusion factories and metal surface treatment workshops.

1. Alternating acid and alkaline wastewater leads to severe pH fluctuation; ordinary equipment fails to maintain stable water quality, bringing high risks of environmental penalty.
2. High-concentration aluminum ions form colloids, resulting in turbid white effluent with suspended solids and heavy metals hard to remove.
3. Dyeing & electrolytic coloring wastewater contains nickel and tin metal ions, which cannot be stably eliminated by conventional treatment technology.
4. Traditional devices rely on manual chemical dosing with high reagent consumption and large sludge output, increasing long-term operation costs.
5. Strict environmental supervision makes unqualified discharge easily lead to fines and forced production suspension.

1. Customized for Aluminum Oxidation Wastewater, Stable Standard Discharge
   Developed according to the special characteristics of anodizing wastewater, simultaneously removing acid, alkali, aluminum ions, nickel & tin heavy metals and COD. It stably meets local discharge standards, one-time pass of EIA and sewage acceptance, avoiding shutdown risks.
2. Full Anti-Corrosion Structure Adapted to Harsh Workshop Environment
   All tanks, pipelines, valves and pumps are made of UPVC, PP and stainless steel with strong acid & alkali resistance, free of leakage and rust to extend service life and reduce maintenance costs.
3. Fully Automatic PLC Operation, Low Labor Cost
   Integrated intelligent control system realizes automatic water pumping, proportional chemical dosing and automatic sludge discharge. Online pH and conductivity monitors are equipped. No full-time staff on duty is required, only regular patrol inspection needed to save labor expenses.
4. Resource Recycling & Low Operating Cost
   Cooperate with MEIAL aluminum ion stabilizer to recover sulfuric acid from oxidation tanks and reduce chemical consumption. Purified water can be recycled for workshop rinsing to cut water bills. High dryness sludge reduces hazardous waste disposal cost.
5. One-Stop Matching with All MEIAL Oxidation Lines
   Compatible with automatic horizontal anodizing lines, vertical oxidation lines, manual oxidation lines, mini parts oxidation lines and MAO micro arc oxidation lines. We provide unified factory layout planning, installation, commissioning and technical training for production lines and environmental equipment together.
6. Customized Size & Capacity for Different Factories
   Design integrated or split wastewater treatment systems according to daily wastewater volume, monthly aluminum output and plant space. Small compact models for small workshops and large complete sets for large extrusion factories are both available.

Besides wastewater treatment equipment, MEIAL also supplies three-acid mist treatment system. Acid & alkali waste gas generated from oxidation, polishing and caustic etching is collected, sprayed and neutralized to reach emission standard before high-altitude discharge. One-stop solution for both waste gas and wastewater solves all environmental acceptance requirements of your workshop.

Architectural aluminum profile automatic oxidation & coloring workshops, new energy auto aluminum component production lines, 3C electronic mini part anodizing & MAO workshops, hardware electrophoresis coating factories, small manual oxidation sampling workshops. Our equipment serves domestic aluminum industrial bases and exports to Malaysia, Indonesia, Vietnam and other Southeast Asian aluminum manufacturers.

Guangdong ME-AL Technology provides one-stop service including factory layout planning, process design, environmental equipment manufacturing, on-site installation & commissioning, operator training and lifelong after-sales maintenance. Professional water quality debugging and chemical proportion guidance are offered to guarantee stable compliant operation of your wastewater system.
