Aspects to Consider during Implementation of Biogas

 

Health Aspects/Acceptance

For direct use, the following applying conditions should be kept:

  • In some cases, especially at larger scale, further treatment of biogas is required to remove traces of water, carbon dioxide or hydrogen sulphide, before it is ready for use
  • Safety measures are needed in order to reduce the risk of explosion in case of leakages from the storage.

Operation & Maintenance

  • Condensation is likely to occur since Biogas is normally fully saturated with water vapour : 

- It is recommended that water traps be installed so that water can be easily removed when accumulated.

- this would aid in preventing blockage of pipelines and also corrosion

- The gas pipelines, fittings and appliances must be regularly monitored by trained personnel.

  • When using biogas for an engine, it is necessary to first reduce the hydrogen sulphide because it forms corrosive acids when combined with condensing water.

  • The reduction of the carbon-dioxide content requires additional operational and financial efforts: 
- CO2 "scrubbing" is only not necessary when biogas is used for cooking

Cross-contamination in Food processing Plants

Cross-contamination in food processing facilities can occur in ways that may not even be visible as  there are many unexpected ways in which bacteria can travel. Awareness of these potential causes of cross-contamination will aid in the maintenance of a sanitary food processing environment . Post-Harvest Contamination Workers that go from the area of sorting the raw material upon arrival to processing zones are susceptible to spreading bacteria from unclean hands touching food or food-contact surfaces. Cross-Contamination from Storage Bins Stacking storage bins directly onto soil or areas outside the processing facility and then bringing the containers into the facility can also bring bacteria into a clean environment.   Contamination from Footwear When employees walk in fields, compost sites, or other areas outside of clean zones, they can bring bacteria into a processing facility on their feet.    Contamination from Mobile Equipment The same challenge a...
