Not all treatment plants are created equal. They can vary significantly based on the type of wastewater being treated, the scale of the facility, and the technology employed. Operators understand that every facility has its unique challenges and triumphs. The opportunity to tour other treatment plants provides valuable insights into different approaches, technologies and best practices. In this video, @brunswicksewerdistrict gives us a one-minute tour of their treatment plant. Collaborating and exchanging knowledge among members of the wastewater treatment community is key to enhancing our industry!

The video begins at the headworks, the initial point of entry for all of Brunswick's wastewater into the plant. Subsequently, the wastewater proceeds to the primary settling tank, where biosolids are separated from the wastewater, eliminating approximately 60% to 70% of settleable waste. Following this, the wastewater flows through the trickling filters containing biofilm, which effectively removes organic matter from the waste stream. After passing through the trickling filters, the wastewater enters the distribution box, ensuring an even distribution to the secondary clarifiers. 

The video then showcases one of these secondary clarifiers, where humus settles out of the waste stream and is then directed back to the headworks. Finally, the wastewater enters the chlorination tanks, where it is treated with hypochlorite to disinfect it. Before discharge into the Androscoggin River, the hypochlorite is neutralized using bisulphate.

In conclusion, touring different treatment plants, like the one showcased in this video, offers valuable learning opportunities for operators. By observing and understanding the diverse approaches, technologies and practices, operators can gain fresh perspectives to apply to their own plants. This exchange of knowledge leads to more efficient and effective wastewater treatment processes. As we continue to share experiences, we contribute to the advancement of our collective goal of improving public health and the environment.
