Agrico unveils novel AD plant protector at World Biogas Expo

Stand A105, World Biogas Expo 2022, NEC, Birmingham, 15-16 June

Anaerobic digestion pump specialist Agrico is using the return of the World Biogas Expo to unveil the new and improved WANGEN X-UNIT; a revolutionary one-step biogas optimisation solution that protects AD plants from damage by harmful contaminants AND increases feedstock surface area to supercharge the digestion process.

Biogas plant operators can protect their equipment and boost their yield with the X-UNIT

By preventing foreign objects from entering the AD system, the X-UNIT protects pumps, mixers, pipework and tanks from contaminant damage, while its chopping blades reduce AD feedstock to a fine, porridge-like consistency, optimising the anaerobic digestion process. This easy-to-operate, energy-efficient system extends the lifespan of valuable equipment, increases operational uptime and maximises biogas yield, boosting an operator’s bottom line.

“Having seen first-hand the considerable damage caused to downstream equipment by contaminants like bone, metal, stones and grit, I am excited to showcase the new and improved X-UNIT at the World Biogas Expo when it returns to the NEC this June,” says Agrico’s General Manager John Tame. “Not only can it play an important role in protecting biogas systems, but it helps plant operators extract the maximum gas yield from every tonne of feedstock – essential in the current climate where competition for feedstock is fierce and gas prices are at a record high.”

A modular system that can be retrofitted to the suction side of all makes of positive displacement pumps, the X-UNIT comprises two elements: the X-CUT, a high-performance chopper; and the X-TRACT, which separates contaminants from feedstock. As feedstock passes through the X-TRACT on its way to the digester tank, a reduction in velocity causes foreign objects to fall into the base of the unit, where they are caught in a settling tank and prevented from entering the wider AD system and subsequently damaging valuable downstream equipment.

Contaminants such as stones, metal and bone fall into the X-UNIT’s debris catcher, from where they can be easily removed

Without the X-UNIT to screen out debris, foreign contaminants would ultimately settle in one place – the floor of the primary digester tank. “A build-up of solids in the digester can have a severe impact on a plant’s success by reducing tank volume, resulting in reduced gas output and directly affecting profitability,” says John. “There is also the cost of removing the compacted sediment, which can reach hundreds of thousands of pounds. By preventing solids from entering the AD system in the first place, the X-UNIT protects plant operators from the risk of this expensive occurrence.”

A modular solution that can be retrofitted to any progressive cavity pump, the X-UNIT comprises the X-TRACT and the X-CUT

Featuring a maximum flow volume of 1,250 m3/h, low energy consumption, low wear costs and accessible parts for ease of maintenance, the X-UNIT is designed for longevity. “UK AD plant operators can now protect their investment and optimise their biogas output with the best of German engineering from WANGEN, backed up by on-the-ground, local sales and servicing support from Agrico,” adds John.
