a diagram illustrating a household wastewater treatment system. It depicts how wastewater from a house is treated through a series of underground tanks and then discharged using various methods. The image uses a cutaway view to show the internal components of the treatment system.
Key Features and Components:
1. House:
* A typical house is shown with a partial cutaway view to reveal the plumbing inside (toilet, sink, etc.). This establishes the source of the wastewater.
2. Grease Trap (Trampa de Grasas):
* The initial stage of treatment.
* Labelled with "Grasas" (greases) and "Fase Liquida" (liquid phase), indicating the separation of grease from the wastewater.
* Small diameter outflow pipe
3. Septic Tank (Tanque Séptico):
* Receives wastewater from the grease trap.
* The tank is divided into three layers: "Nadas" (scum/floatables), "Fase Liquida" (liquid phase), and "Lodos" (sludge). This shows the separation of solids and liquids through settling.
* Larger diameter outflow pipe.
4. Anaerobic Filter (Filtro Anaerobio (FAFA)):
* Located after the septic tank.
* Contains a "Capa Biologica" (Biological Layer) and a "Lecho filtrante" (filter bed), indicating a biological treatment process.
* "Rotoplast" may indicate brand of the tanks.
5. Discharge Options:
* The treated wastewater can be discharged through one of four options:
* Opción 1: Riego (Irrigation): Shown as a hose connected to a tap. Implying the treated water can be used for irrigation.
* Opción 2: Campo de Infiltración (Infiltration Field): An underground system where the water is dispersed into the soil.
* Opción 3: Pozo de Absorción (Absorption Well): A pit or well where the water is discharged and absorbed into the ground.
* Opción 4: Corriente de Agua (Water Stream): Indicates the treated water can be discharged into a river or other water body.
6. Environment:
* The image is set in a somewhat rural environment, with grass, a tree, and a body of water.
Detailed Observations:
* System Flow: The image clearly shows the flow of wastewater from the house, through the treatment system, and then to various discharge points.
* Treatment Stages: The system utilizes primary (grease trap), secondary (septic tank), and potentially tertiary (anaerobic filter) treatment stages.
* Layering in Tanks: The illustration shows how settling and separation occur within the grease trap and septic tank.
* Discharge Options: The variety of discharge options demonstrates the adaptability of the system based on environmental conditions and regulations.
* Spanish Labels: The image appears to be intended for a Spanish-speaking audience, as all the labels are in Spanish.
Overall Interpretation:
The image provides a visual explanation of a household wastewater treatment system. It illustrates the treatment process, the components involved, and the different ways in which treated wastewater can be managed. The diagram is likely used for educational purposes or for explaining the system to homeowners or installers.
