"Alfa Laval’s spiral heat exchangers are vital equipment for stable operation of our digester and overall plant economy as it saves a lot of money through heat recovery," - Lars Albak Kristensen, Plant Manager, Lemvig Biogas Plant
AGSM (Azienda Generale dei Servizi Municipalizzati) in Verona, Italy, uses an ALDRUM MegaDuo to thicken solid waste from 5% to 13% DS without using polymers. The sludge is then transferred to an anaerobic digester to produce biogas.
Pre-treatment in the biogas production process
When treating municipal solid waste in a wet system before anaerobic digestion, several steps take place, including milling, magnetic separation, pulping, inert separation, thickening, and hygienization. Thickening the pulp using Alfa Laval drum thickeners and decanter centrifuges offers benefits such as reducing the load on downstream processes, lowering energy consumption, and increasing biogas yield. The water from the pulp can also be recycled. Regulations often require hygienization and can be achieved through pasteurization using efficient spiral heat exchangers, which help maintain stable anaerobic digestion by controlling the sludge temperature closely.
Anaerobic digestion in biogas generation
Anaerobic digestion is a crucial stage in which microorganisms break down the pulp without oxygen, producing methane and carbon dioxide gas. Prior stages aim to optimize the digestion process by increasing dry solids feed, controlling temperature, and enhancing capacity and biogas yield. Post-digestion stages such as dewatering and nutrient recovery are vital for closing the loop, supporting biogas processing and sustainable energy generation, which Alfa Laval achieves through high-performance decanter centrifuges. Spiral heat exchangers can also be used for post-digestion hygienization, offering benefits similar to those in the pre-treatment stages.
Oil separation in anaerobic digestion for diversified biofuel production
Oil separation in anaerobic digestion for a diversified revenue stream
Alfa Laval is working with AD operators globally, placing the Prodec Oil Plus decanter centrifuge between the acidogenesis and acetogenesis stages of anaerobic digestion, creating ideal conditions for oil separation. The innovative decanter centrifuge near the pasteurizer allows for slurry separation without impacting the overall process. The unique operation of the decanter prevents solids from compacting within the chamber, ensuring that all oil introduced into the machine can be fully recovered.
