Title: The Importance of Segregating Wastewater Streams in Heavy Metals Removal Applications
Learner Objectives:
The objective of this presentation is to demonstrate why the proper segregation of waste streams is at least as important as treatment chemical selection in heavy metals removal applications.
Content/Topic Outline:
There are three main reasons for proper segregation of waste streams in heavy metals removal applications:
Each of these points will be supported with specific examples and data.
Presenter:
Chandler Mancuso will be the sole presenter.
Presentation Description:
In heavy metals removal applications, the generated wastewater comes from a variety of sources throughout the process line(s) in the facility. Each waste stream comes with a unique set of safety precautions as well as its own challenges for minimizing its impact on the consistency and effectiveness of the overall wastewater treatment operation. Therefore, it is imperative that the proper segregation of the individual waste streams is considered in conjunction with the careful selection of wastewater treatment chemistries to fully optimize the performance of the treatment process.
Safety is the primary focus when strategizing how to segregate various waste streams. Some wastewater contaminants and treatment additives have known incompatibility with chemicals that can be found elsewhere in the wastewater treatment system, so care must be taken to ensure that the process is conducted in a safe manner. Appropriate segregation and sequencing of wastewater flows is a critical tool for maintaining a safe treatment operation.
Wastewater matrices are complicated, and for a multitude of reasons, the sequence of introducing the different waste streams into the process can greatly alter the difficulty in achieving total compliance in the final effluent. Segregating the waste streams provides more opportunities to select when and how to mix various waste streams together, minimizing chemical consumption and reducing the overall complexity of satisfying treatment requirements.
The generation of wastewater from the production process is rarely consistent. While some of the wastewater is generated on a continuous basis, other sources of wastewater are generated in batches, such as scheduled process tank dumps and unexpected process interruptions. A large influx of concentrated wastewater can induce significant challenges with maintaining adequate treatment performance in the wastewater system, even if the addition sequence and treatment program have been optimized. Therefore, isolating and storing concentrated waste streams creates improved flexibility and consistency in the wastewater treatment operation by allowing for a controlled introduction of challenging wastewaters into the treatment system.
This presentation is intended to discuss these topics in more detail and support them with case examples, enhancing the audience’s perspective and providing the necessary tools to conceptualize a holistic approach to heavy metals removal applications.
