Are You Facing These Metallurgy Wastewater Treatment Challenges?
We deeply understand the challenges you face in your operations and provide targeted solutions.
High Treatment Costs
Traditional processes have high energy consumption and huge chemical costs, leading to persistently high operational expenses.
01
Strict Environmental Standards
National environmental policies are becoming increasingly stringent, and wastewater discharge standards continue to rise, posing compliance pressure.
02
Difficult Resource Recovery
Wastewater contains valuable resources like metals and acids, but low recovery rates lead to resource waste.
03
Unstable Equipment Operation
Equipment is prone to corrosion, scaling, and clogging, leading to unstable operation and a heavy maintenance workload.
04
Complex Process Flow
Long process routes, large footprints, and complex operations and management make automation difficult.

Facing the Challenge: Characteristics of Metallurgical Wastewater
Wastewater from the metallurgy industry is notoriously tough to treat, with difficulties stemming from these four main characteristics.
1
Wastewater contains large amounts of inorganic salts, with TDS reaching tens or even hundreds of thousands mg/L.
2
Contains various pollutants like organic matter, COD, and ammonia nitrogen, making treatment difficult.
3
Contains valuable or toxic heavy metal ions like nickel, cobalt, and zinc, requiring proper recovery.
4
Wastewater can be highly acidic or alkaline, demanding high-grade, corrosion-resistant equipment materials.
Core Solutions
We provide refined, customized solutions for the specific needs of different processes in the metallurgy industry.
Hydrometallurgy Wastewater Treatment
For high-salt, high-COD wastewater from hydrometallurgy (e.g., nickel, cobalt, copper), we use a "Pretreatment + MVR Evaporation + Crystallization" process to achieve water reuse and salt resource recovery.
✅High concentration ratio, significant volume reduction
✅High-quality crystallized salt, usable as industrial raw material
✅Near-zero liquid discharge, meeting environmental standards
Waste Acid Treatment and Resource Recovery
For waste acids from steel pickling or electroplating, we use technologies like diffusion dialysis and evaporation to recover acids and separate metal salts, turning pollutants into valuable products.
✅Acid recovery rate up to 90%+
✅Reduced hazardous waste disposal costs
✅Achieves a closed-loop acid cycle
Multi-Metal Smelting and Resource Recovery
In multi-metal smelting, we concentrate leaching solutions and raffinate through evaporation, enriching valuable metals and increasing recovery rates for subsequent purification.
✅Increases direct metal recovery rate
✅Simplifies subsequent process flows
✅Reduces overall energy consumption
Typical Wastewater Treatment Process Flow
A scientific and rigorous process design is the cornerstone of a stable and efficient system.
Pretreatment
Removes suspended solids and organic matter to protect the subsequent system.
Evaporation & Concentration
Uses MVR or multi-effect evaporators to concentrate wastewater and separate pure water.
Crystallization & Separation
The concentrated liquid enters a crystallizer to separate out high-purity salts.
Solid-Liquid Separation & Drying
Dewatered and dried to obtain the final salt product, achieving resource recovery.
