Mixing to maximise anaerobic digestion process

Mixing is a crucial part of the anaerobic digestion process and Huntingdon-based System Mix, which markets the Rotamix System incorp - orating the Vaughan chopper pump, is an established supplier of digester mixing systems at numerous installations across the UK.

Director, Andy Parr, says: "It is crucial to the AD process that suitable pre-conditioning of solids is carried-out prior to digestion and our system has protection technology mean significantly reduced downtime and savings on consumables, says the company. A tough stainlesssteel nozzle guard protects the printhead from possible damage, caused by impact with the boxes on the line, while remaining close enough to the packaging to ensure good print quality.

been proven to be one of the most effective in achieving this.

"The Vaughan pump prevents re-accumulation of fibrous and fatty material in the digester and this means that material continues to pass through the nozzles. This in turn ensures that digestate is adequately conditioned and actually benefits all postdigestion equipment." He concludes: "As many AD operators are now looking to maximise the sustainable credentials of their plant and equipment even further, we are confident that the benefits of our mixing systems are becoming even more important."
