Safe separation of heavy metals and complexing agents in electroplating
Electroplating companies produce large quantities of rinse and process water every day, which is contaminated with heavy metals, acids, alkalis, or complexing agents. Reliable treatment of this water is not only necessary from an environmental perspective, but also makes economic sense—especially in view of increasingly strict legal discharge limits.
With our atmospheric evaporators , we offer a proven, chemical-free solution that can be used to treat even demanding wastewater safely and efficiently – without expensive precipitating agents or complex chemical-physical processes.
Your security during government audits
Unexpected inspections by environmental authorities are not uncommon in electroplating plants. Exceeding nickel, zinc, or copper limits can quickly lead to production shutdowns or fines. Our evaporation systems ensure that you achieve consistently stable discharge limits – regardless of fluctuating wastewater composition.
atmospheric vaporization technology
's targeted evaporation of process water under atmospheric pressure allows heavy metals, complexes, and pollutants to be reliably retained in the concentrate , while the resulting distillate is virtually free of harmful components. For you, this means:
• High operational reliability with changing wastewater compositions
• Cost-efficient operation thanks to automatic control and easy maintenance
Customized solutions for your electroplating
Every electroplating process is different – from small-scale coating to fully automated production lines. MKR designs each system to be tailor-made for your business, based on:
- Type of electrolytes used
- Process sequence (rinsing, activation, pickling, etc.)
- Space requirements and wastewater volume
- Discharge specifications and reuse options
