BET – Banana Sewage Treatment System

In many parts of Brazil, traditional septic tanks pose significant environmental risks. These systems often lack proper maintenance and oversight, leading to:

• Groundwater Contamination: Leaking tanks allow untreated sewage to seep into the soil, contaminating groundwater sources used for drinking and agriculture.
• Surface Water Pollution: Overflowing tanks can directly pollute rivers, lakes, and coastal areas, harming aquatic ecosystems and threatening public health.
• Odor and Health Hazards: Improperly functioning septic systems emit foul odors and can attract disease-carrying insects and rodents.

The BET Banana System: A Sustainable Solution

The BET (Bio-Evap-Transpiration) Banana Sewage Treatment System offers a promising alternative to traditional septic systems. This innovative approach utilizes the natural power of banana plants to effectively treat wastewater. It is also incredibly convenient and cheap! No more calling the trucks to haul away the sewage from an overfull septic tank.

How it Works:

1. Wastewater Collection: Wastewater from the household is collected and directed into a specially designed basin.
2. Biological Treatment: Within the basin, a complex microbial community breaks down organic matter in the wastewater, reducing pollutants like bacteria and pathogens.
3. Evapotranspiration: Banana plants are strategically planted within the basin. Their extensive root systems absorb water from the treated effluent, while their leaves release water vapor into the atmosphere through transpiration.
4. Nutrient Uptake: Banana plants efficiently absorb nutrients from the treated wastewater, further purifying the effluent and utilizing it for their own growth.

Key Advantages:

• Environmental Sustainability: Reduces groundwater and surface water contamination, minimizing environmental impact.
• Social Benefits: Provides a sustainable and affordable sanitation solution for rural and underserved communities. Relatively low construction and maintenance costs compared to conventional sewage treatment systems.
