History of Anaerobic Digesters in Northern Ireland Here!

6 Working Examples on farm wastes

 

1.1 Anaerobic Digesters for Farm Waste

We have built anaerobic digesters that have been processing the following feedstocks for up to 12 years and are still going strong:

1.2 Anaerobic Digesters for vegetable processing wastes

Special problems with large grit and irregular loading can be accommodated in designs for vegetable processing.

1.3 Anaerobic Digesters for food processing wastes

Starch, fatty wastes, rendering byproducts can all be digested in a suitably designed system or blended with other wastes to produce high grade end products and good economics.

1.4 Anaerobic Digesters for fish farm wastes

The special problems associated with fish wastes can be engineered out and our digestible ensiling products are a real solution to odour reduction and subsequent digestion.

1.5 Composting Systems

Windrow and in- box composting systems for digested fibre and undigested organic wastes.

2.0 CHP UNITS FOR BIOGAS

2.1 AJAX based low speed two stroke cogeneration( CHP) units for unrefined biogas .

Producing the lowest maintenance cost and longest life of any engine in its size range, these units are now established as the most economic and reliable systems for converting unrefined biogas into electricity and hot water. No gas clean up costs, ultra-low maintenance costs, little time lost in management, the best long term performance of any reciprocating engine. Check out the list of UK installations fuelled on unrefined biogas.

 

2.2 AJAX based, ultra reliable low speed two stroke electricity generators without heat recovery (landfill gas engines) - at design stage.

 

 

2.3 Scada systems, data aquisition and telemetry

We build access to our plc controllers for many customers requiring scada connection. However, if you are not committed to a particular system, allow us to quote for a specialised unit that will acquire data from the chp plant, digester or other sensor array , store it and transmit it to any PC on the planet via any type of telephone or cellnet /vodaphone connection.
