Tutorial definitivo BIODIGESTOR!!!

Installation of a Self-Cleaning Biodigester 1. List of Materials and Tools Materials: Self-cleaning biodigester (according to the required capacity). Sanitary PVC pipe (110 mm or 160 mm, depending on the design). PVC elbows, couplings, and fittings. PVC cement for pipe bonding. Sand and gravel for compaction. Dry sand and cement mix (6:1) for structural backfill. Concrete base (optional, if the ground is unstable). Prefabricated or on-site inspection chamber. Sludge collection chamber for annual biodigester cleaning. 50 mm PVC vent pipe. Materials for the nitrification bed in the trench: Gravel or large stones (Ø 40 mm or larger) – 40 cm thick. Perforated PVC pipe (110 mm or 160 mm, depending on capacity). Geotextile or nylon liner (200 microns). Covering soil (30 cm thick). Tools: Shovel and pickaxe for excavation. Measuring tape and spirit level. Wheelbarrow for transporting material. PVC saw or cutter. Troof and mason's trowel (if using concrete). Manual or mechanical compactor. Drill with a suitable bit for drilling pipes. --- 2. Installation Procedure Site Selection and Preparation 1. Choose a firm and accessible site with a suitable slope for effluent flow. 2. Mark the excavation area, taking into account the dimensions of the biodigester. 3. Excavate with sufficient clearance for maneuvering. Biodigester Placement 1. Level and compact the base of the excavation. 2. If the ground is soft, construct a 10 cm thick concrete base. 3. Place the leveled biodigester in the excavation. 4. Fill the biodigester with water to 50% of its capacity before continuing with the backfill (this prevents it from shifting or deforming during the process). 5. Fill the space between the biodigester and the ground with a 6:1 mix of sand and dry cement, ensuring that this space is at least 5 cm. 6. Carefully compact the material in 20 cm layers to ensure stability. 7. Connect the inlet pipe from the inspection chamber. 8. Connect the outlet pipe to the nitrification bed in the trench. 9. Install the sludge access chamber, ensuring easy access for annual cleaning. 10. Check and seal all joints with PVC cement. Ventilation Installation The vent pipe will be installed in the inspection chamber upstream of the biodigester, preventing oxygen from entering the biodigester to protect the anaerobic bacteria. It must be raised at least 50 cm above the surface and located in a safe area. --- 3. Construction of the Nitrifying Bed in a Trench This system allows for filtration and improvement of the effluent quality before it infiltrates the soil. Dimensions and Characteristics: Minimum width: 50 cm. Minimum depth: 70 cm. Length: between 15 and 20 meters (depending on the biodigester's capacity). Layers of the Nitrifying Bed in a Trench: 1. 40 cm of large-grained stone or gravel (40 mm or more) at the base. 2. Perforated PVC pipe, placed on top of the stone. 3. 200-micron geotextile or nylon sheeting to prevent the soil from coming into contact with the stones and the pipe. 4. 30 cm of cover soil over the sheeting. Drilling the drainage pipe: Drill holes in the bottom of the pipe, on both sides, at a 45° angle. The holes are spaced 5 cm apart along the entire length of the pipe. Installing the nitrifying bed in the trench: 1. Excavate the trench to the appropriate dimensions. 2. Place 40 cm of large stones or gravel at the bottom. 3. Install the perforated drainage pipe on top of the stones. 4. Cover the pipe with 200-micron geotextile or nylon sheeting. 5. Fill with 30 cm of cover soil. --- 4. Start-up and Verification 1. Fill the biodigester with water to its operating level. 2. Check all connections and ensure there are no leaks. 3. Observe the effluent flow into the nitrifying bed in the trench. 4. Monitor the system during the first few days to detect any potential problems. --- 5. Sludge Maintenance and Cleaning Annual system inspection, including sludge removal through the inspection chamber. The extracted sludge can be used as fertilizer. #biodigester #construction #architecture #gatedcommunities #construction #constructionargentina #sludgechamber #sludgeinspection #absorptionwell
