Waste Acid Treatment Systems
The Waste Acid Treatment System developed by Proses Makina is designed to effectively control and neutralize waste acids or bases generated at the end of hydrometallurgical operations, particularly in precious metal refining processes. The waste acid produced at the end of PGMs refining processes can pose significant environmental risks, and it is critical to treat these waste liquids to ensure compliance with national environmental regulations. The neutralization process is mandatory to bring the wastewater to safe, environmentally acceptable levels.
Key Features of the Waste Acid Treatment System
- Compliance with Environmental Standards: The system neutralizes wastewater to pH levels between 7 and 8, protecting rivers, aquatic life, and preventing corrosion-related damage.
- Materials Used: The neutralization units are manufactured from materials such as polypropylene (PP) or high-density polyethylene (HDPE), depending on the pH characteristics of the waste acid. These materials ensure durability and compliance with environmental management standards, which must be verified through testing.
System Functionality
- Automatic Feeding System: Ensures the optimum pH range is maintained during the neutralization process, automatically adjusting the feed of neutralizing agents as needed.
- Circular Economy Contribution: The system promotes sustainability by allowing for the reuse of acid/base after the neutralization process, reducing the overall consumption of chemicals.
- Excellent Integration: The neutralization system integrates seamlessly with other processes, including chemical preparation and sedimentation tanks, ensuring smooth operation.
- Gradual Sedimentation: The system provides gradual sedimentation to achieve environmental limits on the discharge of treated wastewater.
- High Separation Efficiency: The filter press system offers excellent separation rates, ensuring the effective removal of contaminants and enabling compliance with environmental discharge standards.
The Waste Acid Treatment System ensures the safe and efficient treatment of acidic waste from refining operations, contributing to sustainability, regulatory compliance, and environmental protection.
