Anaerobic Digestion (AD) is a complex biochemical process involving a variety of microorganisms to produce biogas. The process is by no means homogeneous. AD involves several distinct steps performed by unique microorganisms which need specific individual conditions for optimum biogas production. To facilitate this suggests a multi-stage process for the best outcome. Conversely, to carry out the process in a single stage chamber will mean that the function of the various microorganisms cannot be optimised. Our CENTRIGAS® takes nature as its model, similar to cow`s stomach, by facilitating three separate process stages. The first stage provides ideal living conditions for hydrolysis and acidification processes, followed by methane production under optimal conditions in a separate fermenter.

Solves the sand and grit problem in AD plants. Thus avoiding: reduced digester volume, reduced gas production, reduced mixing efficiency, process disruption costs, sand extraction costs, wear and tear on equipment
