pH Neutralization Efficiency
Solution
Containerized pH Neutralization System
Problem
The facility required an efficient, modular solution to handle wastewater with fluctuating pH levels between 2 and 12 at a flow rate of 150 gallons per minute (gpm). Regulatory compliance and environmental sustainability were critical, necessitating a solution that could accurately neutralize the pH before discharge.
Solution
Key Features:
- Prepackaged System: The pH adjustment system includes automated controls and instrumentation, minimizing installation time and ensuring reliability.
- Continuous Neutralization: Designed to process 150 gpm of wastewater with a retention time of 20 minutes, the system efficiently doses sulfuric acid and sodium hydroxide to maintain pH levels between 6.5 and 8.5.
- Advanced Controls: The system uses a PLC-controlled setup with sensors and proportional chemical dosing for accurate pH management. A recirculation pump ensures thorough mixing, while a second pH probe monitors the effluent stream.
- Reagent Dosing: Two sets of metering pumps enable fine and coarse adjustments for precise reagent dosing. This dual approach enhances the accuracy of pH control, reducing reagent waste.
- Safety Features: The containerized system provides insulation, heating, and lighting, ensuring a controlled environment. Safety features include pH sensors, float switches, and level transmitters to prevent system failure.
- Hybrid Batch Process: The system employs a hybrid batch treatment process, allowing wastewater to recirculate if out-of-spec, ensuring compliance before discharge.
Implementation
The pre-assembled system was delivered to the facility, reducing on-site assembly time. Key steps included:
- Placement of the container near the wastewater inlet and outlet.
- Connection of plumbing and wiring to the existing infrastructure.
- Calibration of pH sensors and optimization of metering pumps for proportional dosing.
Results
The implementation of the containerized pH adjustment system provided significant benefits:
- Consistent regulatory compliance, with effluent pH maintained between 6.5 and 8.5.
- Cost savings due to precise reagent usage and minimal downtime.
- Operational safety ensured by automated controls and built-in fail-safes.
