Trickling Filter at the wastewater treatment plant (utilities)
Summary
TLDRIn this informative video, Bruce the water guy explains the functioning of a trickling filter, an old but effective technology for wastewater treatment. He details how gravity-driven mechanisms distribute water over a rock media, where microorganisms thrive in a biofilm. These microorganisms play a crucial role in breaking down waste products and nutrients. After treatment, the water goes through a clarifier to settle solids before being disinfected and returned to the environment. Bruce emphasizes the system's efficiency, showcasing the importance of such technologies in maintaining clean water standards.
Takeaways
- 😀 A trickling filter is an old wastewater treatment technology that cleans water using gravity-driven distribution.
- 💧 Water is pumped to the end of rotating arms, which then distributes it evenly over a rock media.
- 🌍 The rock media, original from 1963, provides a surface for microorganisms to grow and treat wastewater.
- 🦠 Microorganisms form a biofilm that breaks down waste products, utilizing them as an energy source.
- 📏 The rock media is about six feet deep and offers approximately 11 square feet of growth area per cubic foot.
- ⚙️ After treatment in the trickling filter, the water flows to a clarifier for further processing.
- 🛠️ The clarifier allows solids and microorganisms to settle out of the water before further treatment.
- 🔄 Settled solids are pumped to a primary tank and then sent to a digester system for energy utilization.
- 💧 The end result is clean water, which is disinfected before being returned to the environment.
- 👨🔧 Bruce emphasizes the importance of older treatment systems and their role in sustainable water management.
Q & A
What is the main function of the trickling filter?
-The trickling filter is used to clean wastewater by utilizing microorganisms that break down waste products.
How does the distribution mechanism in the trickling filter work?
-The distribution mechanism operates by gravity, allowing wastewater to be pumped out and evenly distributed over the media.
What material is used as the media in the trickling filter?
-The media consists of rocks, which provide surface area for microbial growth.
When was the trickling filter built?
-The trickling filter was built in 1963.
What role do microorganisms play in the trickling filter?
-Microorganisms grow in a biofilm on the media and are responsible for breaking down waste products and utilizing nutrients for energy.
How deep is the media in the trickling filter?
-The media is about six feet deep.
What happens to the water after it exits the trickling filter?
-After exiting, the water goes to a clarifier where solids and microorganisms settle before being pumped into a primary tank.
What is the purpose of the clarifier in the treatment process?
-The clarifier allows for the settling of solids and microorganisms, ensuring that only clean water is returned to the environment.
How is energy utilized in this wastewater treatment system?
-The solids collected in the primary tank are sent to a digester system, which processes them to generate energy.
What is done to the water before it is returned to the environment?
-The water is disinfected before being released back into the environment.
