Use a supplied, engineered digester and trained installation. This guide does not provide an improvised flammable-gas vessel recipe.
- 1Measured feedstock and dilution water
- 2Engineered digester; no tank entry
- 3Treatment, condensate, isolation and relief
- 4Compatible burner and fenced digestate storage
Site and operating requirements
- Weigh available feedstock daily, record dilution water and temperature, and have the supplier approve siting and loading.
- Require trained installation, approved gas appliances, pressure relief, condensate and H₂S management, ventilation and a safe excess-gas strategy.
Tools and measuring equipment
- Owner logbook, feed/water measuring tools and the supplier’s inspection equipment; gas testing and commissioning equipment belong to trained personnel.
Output and operating conditions
Sistema 8 vendor example: 2.5 m³ biogas/day under its stated warm-climate manure conditions. Electrical kWh cannot be stated without gas composition and generator consumption.
Vendor-specific gas figure, not an electricity rating or guaranteed output for every climate/feedstock.Parts, quantities and dimensions
| Part | Quantity | Specification / dimensions |
|---|---|---|
| Engineered digester | 1 | Select the model from verified daily feedstock and water. Sistema 8 equipment dimensions in the 2026 catalogue: about 3.4 × 6.2 m; installation area is separate. |
| Gas treatment and controls | matched set | OEM pressure relief, H₂S filter, water traps, approved pipework and matched gas appliance. |
| Civil works and digestate handling | site sized | Engineered trench, drainage, exclusion area and sanitary handling; confirm all current drawing dimensions. |
Preparation and component checks
- Prepare the supplier-approved site, drainage, fencing and initial water/feedstock. Confirm trench and gas-line drawings, appliance compatibility and digestate handling before installation.
- Have trained personnel commission leak tightness, relief, gas treatment and burner operation; never leak-test with a flame or enter a tank.
- Owner operation starts after documented training. Keep permitted feed, dilution, pressure and inspection limits visible; route unexplained pressure or gas loss to service.
Procedure
- 1
Record daily feedstock, water and temperature before choosing the model.
- 2
Obtain the OEM’s installation drawings, gas-use limits and training.
- 3
Use trained installation for civil works, gas treatment, relief devices and approved end-use equipment.
- 4
Commission and leak-test under the supplier’s procedure; establish inspection and digestate-handling routines.
Safety and inspection
Biogas may contain flammable methane and toxic H₂S. No indoor gas-storage experiments; use trained professionals and local approval.
Verify the result
Do not infer electrical output from digester volume. A generator needs measured fuel use and suitably treated gas.
Measurement log
- Feed kg/day, dilution L/day, temperature, OEM pressure range, gas-use time, digestate quantity, faults, service visits and measured gas quality where required. Gas volume is not electrical kWh.
Maintenance and repeat checks
- Follow the model-specific inspection schedule for gas lines, condensate traps, H₂S treatment, relief and fencing. Isolate and call service for leaks, blocked lines or recurring relief events.
Troubleshooting
- No output, abnormal heat, noise, vibration or leaks
- Stop and isolate first. Check the documented input, load compatibility, alignment and connections; keep guards fitted and refer specialist systems to their installer.
