Como é feito o TRATAMENTO DE ESGOTO #Boravê
Summary
TLDRThis informative video takes viewers through the intricate process of wastewater treatment at a facility in Vitória, Brazil. It highlights how sewage from homes is transformed into clean water using microorganisms in a series of specialized tanks. Key stages include removing large debris, treating the water in oxygen-rich environments, and finally purifying it with ultraviolet light before it's released back into nature. The video emphasizes the importance of proper waste disposal practices and educates viewers on the critical role of treatment plants in protecting the environment.
Takeaways
- 🌊 The treatment plant processes wastewater to return clean water to nature, using a variety of natural processes.
- 💧 Wastewater contains organic matter, including human waste, that needs to be treated before being released back into the environment.
- 🔬 The treatment relies on activated sludge, a mass of microorganisms that consume waste, effectively cleaning the water.
- 🚫 Non-biodegradable waste, like plastic and dental floss, should not be disposed of in toilets as it clogs the system.
- 🧴 Chemical cleaners are generally safe, but corrosive substances like caustic soda can damage plumbing and should be avoided.
- 🍽️ Used cooking oil should be properly disposed of to prevent clogging; it can be collected and recycled instead of being poured down the drain.
- 🦠 The process involves multiple stages, including sedimentation and aeration, to break down and remove solids and pollutants.
- ⚗️ After treatment, the water is tested for quality before being released; it may not be potable without further treatment.
- 🌧️ Stormwater drains are separate from sewage systems, and mixing them can lead to contamination of clean water sources.
- 🏭 The company operates over 90 treatment stations, emphasizing the importance of proper waste disposal to protect water systems.
Q & A
What is the primary purpose of the wastewater treatment facility discussed in the video?
-The primary purpose is to treat wastewater from homes, removing organic materials and returning clean water to the environment.
What method is used to treat wastewater at the facility?
-The facility uses a process called activated sludge, which involves a mass of microorganisms that consume organic matter in the wastewater.
What are the potential issues caused by improper disposal of waste in toilets?
-Improper disposal can cause blockages in the system, leading to sewage backflow, and harmful substances can enter waterways, affecting ecosystems.
How does the facility manage odors during the treatment process?
-Odors are managed by using biofilters that contain microorganisms and materials like peat and coconut fiber to absorb and neutralize bad smells.
What types of solid waste are removed during the initial stages of wastewater treatment?
-Larger solid waste items are filtered out, including objects larger than 40 mm and smaller debris larger than 3 mm.
What happens to the sand and grit collected from the wastewater?
-Sand and grit are removed from the wastewater and disposed of at a landfill.
What are the three types of tanks used in the treatment process?
-The three types are anoxic tanks (for nitrogen removal), aerated tanks (for aerobic bacteria growth), and settling tanks (for separation of solids).
What is the significance of the final step involving ultraviolet light?
-Ultraviolet light is used to reduce the number of microorganisms in the treated water to levels that are not harmful to health before it's returned to nature.
Why is it important to keep stormwater and wastewater separate?
-Keeping them separate prevents contamination of clean stormwater with sewage, ensuring both systems function properly without causing environmental harm.
What can individuals do to help prevent problems at wastewater treatment facilities?
-Individuals can avoid flushing non-biodegradable items, dispose of cooking oils properly, and minimize the use of harsh chemicals that can damage pipes.
