Food Waste Slurry Pump / Anaerobic Digestion / Organic Matter Disposal
Reducing the cost of food waste disposal into landfill is a key performance indicator for manufacturers today. how processing food waste by removing solids and water allows manufacturers and their recycling partners to extract bio fuel. This can then be sold on to gas utilities and municipal councils.
Anaerobic digestion helps alleviate increasingly punitive Landfill Tax. The slurries are notoriously difficult to process, however Accuvon has found solutions for all types of abrasive and sludge-like mixes.
Organic matter
The facility is fed with kerbside collected food waste, food
processing waste, supermarket food waste and brewery waste
including wastefrom its own outlets. The organic matter enters into
a feed inlet at the start of the process where a rotor chopper
breaks down the raw material.
Rotary lobe pumps move the chopped slurry from holding tanks and
through a heat exchanger to raise the temperature prior to
enteringthe main anaerobic digestion facility. As the hot organic
material enters the main facility it is dosed reliably and
accurately by a Rotarylobe pumps with an inorganic pH buffer to
accelerate and maximise thebreakdown of the material.
The large mass of organic material is ‘churned’ by Rotary lobe
pumps in a plant room connected through a series of pipes to
maximise the surface area and further accelerate the process and
obtain the greatest yield of heat and biogas. The heat is recycled
back into the heat exchanger.

operating principle
• Self-priming, valveless, positive displacement pump
• Designed with two shafts with parallel axes
• The shafts move relatively to one another thanks to external timing gear
• The displacers (=rotors) roll off each other with minimum axial and radial clearance
• In every position, the rotors and casing close the suction chamber against the pressure chamber
• Gentle, low-pulsation pumping
• For viscous, solid, abrasive or shear-sensitive media
Accuvon's range of rotors –the Premium rotor
Premium profile– of biogas rotors
• Large sealing area
• Effective wiper edge
• Pressure-resistant
• Made of steel, stainless steel or plastic
axial and radial casing protection
To protect the pump casing from abrasive media and solids, we developed replaceable casing protection plates and liners several years ago.
The casing protection is replaced in a few steps, based on the MIP principle.
Easy maintenance– Maintenance in Place
• Reduced maintenance times and downtimes
• Maintenance at installation site by customer's in-house staff
