Biodiesel quality depends on what goes into the reactor and how thoroughly the product is cleaned afterwards. Centrifuges are used on both sides of the process: to prepare used cooking oil feedstock, and to separate water and residues from finished fuel.
Where the contamination comes from
Used cooking oil feedstock carries water, food solids and free fatty acids. After reaction and washing, the fuel can still hold traces of water, soap and other residues that affect how it stores and burns.
How centrifugal separation helps
Removing water and solids from feedstock before it reaches the reactor gives the reaction a cleaner starting point. After washing, centrifugal separation helps pull out remaining water and suspended material, so less fuel sits waiting for gravity settling.
A note on safety
Biodiesel processing can involve methanol and other low-flashpoint liquids. Enclosed centrifuge models with explosion-proof motors are part of our range, but suitability always depends on your specific fluids and site. Read our guide to centrifuging low-flashpoint liquids, and talk to us before running anything flammable.
Typical uses
- Dewatering and de-solidifying used cooking oil feedstock
- Cleaning washed biodiesel
- Polishing stored biodiesel before use
