Biodiesel Cleanup

The biodiesel product made with low quality waste feedstock can meet ASTM specifications as a result of our membrane treatment. Below is the analytical result from the sample produced from one of our customers using the waste vegetable cooking oil/animal fats.

Our ceramic membrane filtration system installed at a biodiesel production facility is shown below. Our filter system has been used to replace the conventional adsorption based clean-up technology due to:

Reliability... Our filter is essentially a nanoporous barrier, which can be operated reliably, independent of the variability of the feedstock. In contrast, the conventional technology is based upon adsorption, which is highly dependent upon its specific surface affinity toward contaminants.

Efficiency... Our filter system is configured to operate through cross-flow filtration as opposed to the conventional dead-end filtration. Thus, a steady state operation can be achieved instead of the unsteady state operation practiced by the conventional filter.

Unattended Operation... Since our filter can be operated under steady state, our filtration system is designed to unattended operate.

Finally, our filter can be rejuvenated as a result of accidental poison or long term fouling. Due to its ceramic construction, a variety of cleaners have been used successfully to restore the membrane performance. This is an added insurance to the durability of our filtration system as opposed to conventional polymeric membrane systems.
