WVO Filter VS WVO Centrifuge

First what are these two types of filtering systems?

WVO (waste vegetable oil) centrifuge:

A centrifuge is a piece of equipment, generally driven by a motor that puts WVO in rotation around a fixed axis, applying a force perpendicular to the axis. The oil entrifuge works using the sedimentation principle, where the centripetal acceleration is used to evenly distribute substances WVO of greater and lesser density. Traditional centrifuges use an electric motor to spin a “bowl” at high RPM and create a force like gravity but up to 3000 times the force of gravity. This speeds up particulate and water separation enormously. Separation levels that might take months using only gravity take less than a minute in a centrifuge. And most industrial centrifuges are continuous so dirty WVO can be fed in and clean WVO fuel exits. accumulatMost centrifuges must be stopped to remove the contaminants but some systems are available that allow automated cleaning without stopping the centrifuge.

WVO (waste vegetable oil) Filter:

A gravity or pressure filtration system, the WVO is simply poured into a filter bag placed over a container into which the WVO is collected. These filter bags come in different microns or levels of filtering capability to suit your needs.

Which issuperior well it all comes down to how much WVO you want to process, how much time you’ve to spend processing, how much money do you want to spend, and how hard do you want to work.

With WVO Filter system Oil will run through a 100 micron filter bag at 2-5 gallons per minute however, if the oil is dirty or just creamy the flow rate will deteriorate rapidly.Pre heating the oil helps as does Largerand longer filter bags.  My advice is to only use filter bags after settling. Which means time waiting for the oil to settle. Cartridge WVO filters tee strainers ECT should be used only with heated oil or heating of the filter.Waxy particles in cool oilBigspills are possible.

With WVO Centrifuge “Forced Settling” can clean WVO to sub micron levels as well as removing heavier liquid contaminants such as water.  If you are looking at having to deal with hundreds of gallons or more, a centrifuge is your only solution. WVO centrifuge is required to remove solid and liquid contaminants from the WVO regardless of size. Centrifuges have proven to be quite efficient in the cleaning of waste vegetable oil and reducing the free fatty acids in the pre processing of Biodiesel. They also have proven to remove glycerin during the processing. Contaminant particles as small as 1/10th of 1 micron are removed, all without the use of a disposable expensive filter element. There is simply no betterway to make quality biodiesel quickly. What takes many hours for gravity to separate down a centrifuge can separate instantly in seconds.
