Anaerobic digestion Biogas Production – Verderflex Dura
Recovery of waste food and the production of biogas with Verderflex Dura Pump
The Verderflex Dura Flexible Impeller Pump is used in a brewery to assist in the production of biogas through the process of anaerobic digestion.
A prestigious brewery based in Norfolk, which produces fine quality real ales has installed an anaerobic digestion (AD) facility for producing biogas to be inputted into the national gas grid.
The anaerobic digestion facility is fed with kerbside-collected food waste, food processing waste, supermarket food waste, and brewery waste.
The organic matter is entered into a feed inlet at the start of the process where a rotor chopper breaks down the raw material. Verderflex pumps move the chopped slurry from holding tanks and through a heat exchanger to raise the temperature prior to entering the main AD facility.
As the hot organic material enters the main AD facility it is dosed reliably and accurately by a Verderflex Dura pump with an inorganic pH buffer to accelerate and maximize the breakdown of the material.
The large mass of organic material is ‘churned’ by Verderflex pumps in a plant room connected through a series of pipes to maximize the surface area and further accelerate the AD process and obtain the greatest yield of heat and biogas. The heat is recycled back into the heat exchanger.
Upon completion of the AD process, the digestate and wastewater is pumped from the tank by a Verderflex pump for further use as fertilizer.
The final product of biogas is then filtered and processed further ready to be inputted into the national gas grid.
